My one objection to this is that I would be pretty surprised if any CPUs were not both light and shadow CPUs. I'm not an expert in computer architecture, but my experience with fabricating transistors in a lab course is that positive and negative photoresist are often both used in different steps even in the same process for producing a single transistor. Otherwise very true though, computers are magical thinking crystals.

The problem with writing a fantasy story where they have computers that are powered by magic is that computers are already magic.

Seriously. Moreso than any other subject I know, computers are the ultimate bell-curve, where people who don't know much about how they work and people who know a lot about how they work both agree: they're magic.

Like, do you know how we make computers? We etch intricate patterns in crystals. Using light. The shape of the drawings determines how they work.

Seriously, that's how they're made. We grow super-pure crystals, cut them into wafers, cover them with acid, then shine a light on them through a mask to activate or deactivate the acid, etching away some of the silicon surface. It's called photolithography.

Only we've since decided light is "too big" and we've moved up to using x-rays, which are smaller. This lets us fit smaller drawings on our crystals!

The best part is that because some processes use light to harden the photoresist layer and some processes use light to break it down, it means some computers are made of light (because the parts of the crystal that got light on them remained behind) and some parts are made of shadow (because the parts that got light were washed away.)

Do you have a Light CPU or a Shadow CPU? You'll probably never know. This is industrial secret stuff.

And because we're making them with light, we can make them tiny and we can make lots at once. Like, I found a reference once that said that MOSFETs (a type of electrical switch) is the single thing Humanity has made the most of over our entire time on this planet.

How many have we made, exactly? It's estimated that between 1960 and 2018, we made about 13 SEXTILLION of them.

That's 13,000,000,000,000,000,000,000.

If every human alive (all 8 billion of us) lived to 70 and devoted our whole lives to making them, never sleeping, just making MOSFETs, we'd have to make 736 a second to make 13 sextillion MOSFETs.

Computers are magic. And we're very good at being wizards.

Silicon Back-End Process Episode 7: Wafer-Level Packaging

After summarising conventional package assembly, this article will be the first of two on wafer-level packaging, the other main semiconductor packaging type. Photolithography, sputtering, electroplating, photoresist (PR) stripping, and metal etching — the five core WLP processes — will be covered.

Fully intact wafer packaging

WLP precedes wafer dicing. In fan-in and fan-out wafer-level chip scale packaging (WLCSP), the wafer is intact throughout the process. WLP includes redistribution layer (RDL), flip chip, and through-silicon via1 (TSV) packaging, even though only part of their operations are done before the wafer is diced. Electroplating metal and pattern vary by package2. They all package similarly, as shown below.

After testing, wafers are dielectrically coated as needed. Photolithography exposes the chip pad again after dielectric layer testing.

A metal layer is sputtered on the wafer3. This metal layer helps the electroplated metal layer adhere and blocks metal chemical growth by blocking diffusion. It transfers electrons during electroplating and applies photoresist to create a layer while photolithography designs.

Electroplating coats metal thickly. After electroplating, PR stripping and etching remove thin metal layers. Wafers are electroplated with desired metal layers. This layout wires fan-in WLCSP, redistributes RDL pads, and bumps flip chip packaging. The following sections will examine each step.

Photolithography: Sketching Masked Wafer Pattern

Photolithography combines stone (litho) and drawing (graphy). Photolithography involves applying a photoresist to the wafer and selectively exposing it to light through a mask with a desired design. The light-exposed parts create the pattern. Process sequence is in Figure 2.

Photolithography is used in WLP to pattern dielectric, photoresist pattern electroplated, and etch diffusion layers for metal wiring.

Compare photolithography to photography to understand it.

Figure 3 illustrates how sunlight photographs an object, scene, or person. Photolithography uses a light source to transfer mask designs to an exposure instrument. Finally, film in a camera is like photolithography wafer photoresist.

Figure 4 shows three wafer photoresist application methods. Spin coating, film laminating, and spray coating. Soft baking removes solvents after photoresist application to keep the viscous photoresist on the wafer and thick.

Spin coating spreads viscous photoresist from the centre of a spinning wafer to the edges due to centrifugal force (Figure 5). The wafer photoresist is uniformly thick. If spin speed is low and viscosity is high, photoresist is thick. Thinly apply if viscosity is low and spin speed is high.

To generate solder bumps in wafer-level packages like flip chip, a photoresist layer of 30 to 100 μm thickness is required. Although a single spin coating is difficult to produce the right thickness. Some situations need lots of photoresist and soft baking. Lamination starts the film at the desired thickness, making it effective for thick photoresists. Processing without wafer waste is cheaper. However, rough wafer surfaces can hinder film adhesion, causing flaws. Spray coating uniformly thickens photoresist on rough wafers.

After coating and mild baking, photoresist is lit. The wafer’s photoresist receives the pattern from light through the mask. To remove a positive photoresist that weakens with light, the mask must have holes. A negative photoresist that hardens when exposed to light requires holes in the mask. Mask aligners4 or steppers5 are used for WLP photolithography.

Developer solution dissolves photolithography-weakened photoresist. Figure 6 shows that puddle development pours the developer onto the wafer’s centre so it spins slowly, tank development immerses multiple wafers, and spray development sprays the developer. Figure 7 is a puddle chamber. After puddle development, photolithography patterns photoresist.

Films Sputtering: Wafer Thin

By physical vapour deposition6, sputtering creates a thin metal sheet on a wafer. Under bump metallurgy is the metal layer on flip chip wafers underneath the bumps. Two or three metal film layers consist of an adhesive layer, a current carrying layer that supplies electrons during electroplating, and a diffusion barrier with solder wettability7 to prevent compounds from forming between the plating layer and metal.

Titanium acts as the adhesion layer, copper as the current carrying layer, and nickel as the diffusion barrier. UBM affects flip chip package quality and dependability. Aramid and WLCSP metal wiring layers have adhesive and current-carrying layers to promote adhesion.

Argon gas becomes plasma8 and hits a target with the same composition as the metal on which positive argon ions will be deposited (Figure 8). Collisions deposit metal particles on the wafer from the target. The direction of metal particles in sputtering is constant. Trench or vertical connection access (via) plates can affect flat plates, even though they are uniformly thick. Uneven shapes can thin the wall’s parallel to metal deposition surface below the plate’s floor.

Bonding Metal Layers Electroplating

Electroplating deposits wafer metal ions from electrolyte solution. A reduction reaction with exogenous electrons does this. Electroplating coats WLP wire and electrical bumps with thick metal. Figure 9 shows how the anode oxidises a metal to create an ion and release electrons to the external circuit. Metal ions oxidised at the anode or in solution receive electrons and reduce to metal.

The cathode plate becomes a wafer with WLP electroplating. The anode plate uses an insoluble electrode like platinum and metal to be plated. Metal ions are dissolved and dispersed from the anode plate to maintain solution ion concentration. A wafer-plated insoluble electrode needs periodic metal ion replenishment to maintain ion concentration. The cathode and anode electrochemical reactions are shown in Figure 10.

The wafer’s side faces down and the anode is below the solution when electroplated. Solution flows towards the wafer and hits it hard, electroplating. Photoresist patterns on the wafer to be plated can now contact the solution. Electrons from electroplating equipment at the wafer’s edge encounter metal ions in the solution at patterned areas. Patterns mix with metal ions in the solution to reduce and create metal wiring or bumps.

Photoresist Removal: PR Stripping and Metal Etching

After using photoresist, PR stripping must remove it. PR stripping uses a chemical stripper to develop puddles, tanks, or sprays. The sputtering coating must be removed because electroplating creates metal wiring or lumps. The wafer will short circuit if the metal film is not removed. Acid-based wet etching dissolves metal coatings. As wafer metal patterns become finer, puddle development and PR stripping become more popular.

About Positive Photoresist Material

The photoresist developer can dissolve the portion of the photoresist exposed to light in a positive photoresist. Following that, the developer solution washes away the exposed resist, leaving only windows of the underlying material visible. Positive photoresists can maintain their size and pattern because the photoresist developer solvent does not permeate the areas that have not been exposed to UV light. Positive Photoresist Material has a chemical structure that allows portions exposed to light to develop quicker than sections that are not. Phenol-formaldehyde novolak resins are used to make positive photoresists.

There are so many different methods of printmaking, each with their own character and charms. Linocut prints producing patchy and carefree prints, etching specialising in tone and monoprints creating one-of-a-kind pieces each time. I am personally most inspired by screen printing, also known as silkscreen printing. Screen printing is a form of printing using a screen made of stretched fabric and a frame1. The artist creates a stencil by applying glue, film/paper or photoresist to the areas of the screen that they don’t want printed, then smears ink through the untouched parts of the screen to create a print. This method is primarily used on paper and fabric; however, it is possible to print on other materials such as wood and metal if using specific inks. Screen printing is wildly popular due to its ability to print bright and even colours regardless of the surface2. Screen printing works similarly to a reduction print, creating multidimensional art using layers rather than tone and shading. It is also praised for its ability to produce identical prints in little to no time, making it a key method in the mass production for the likes of posters. Screen printing started being used in the 1920’s for advertisements, even though the method dates all the way back to 221 AD China3, and was being used by artists only 10 years later. By the 1950’s, screen printing had become a widely appreciated media amongst artists. During the 1960’s, screen printing boomed in popularity after pop artists such as Andy Warhol and Keith Harring used it for their designs4. Screen printing was the prime medium for the pop art movement because of the ease at which you could create colourful block shapes and patterns, as well its ability to mass produce designs.  Screen printing has a long and diverse history, but not one that is going to end anytime soon. The method is still wildly popular today amongst printmakers, with its charming characteristic and accessibility maintaining its popularity as strong as ever.  

Ben Rider

Ben Rider is an illustrator and prink maker based in London. Rider is known for his messy neon prints with punk undertones. His work is created using a screen print to bring his illustrations alive, usually in a psychedelic pop art style. One of my favourite pieces of his would be ‘Pleasure Thyself.

This print includes a hand holding to smiley faces, as well as the name of the piece, ‘Pleasure Thyself’. This print is fairly simple; however, I feel as though there's a lot of depth to it. At first glance, it simply seems to be a print about looking after yourself and your mental health. The description of the piece states, ‘In these strange days it's good to be reminded to just be kind to ourselves too!’. I feel as though there could also be a comparison drawn between this piece and drug culture. The hand seems to be holding two smiley faces, which at first reminded me of pills. The slogan of, ‘Pleasure Thyself’ could also relate to the act of getting high or taking an upper. I feel as though the colour pallet helps strengthen this analysis. The piece includes bright pink and yellow, creating a psychedelic feeling. There are also a bunch of lines coming out of the faces, making them the main focus point of the piece. I feel that this also adds emphasis to the pill like shapes. However, some may say that these lines were included to replicate a sun. It could also be argued that this print was inspired by addiction. Many people fall into a dark hole and use drugs as a form of escapism, using the euphoric feeling of being under the influence as a stimulant during hard times. Over all, I feel that this piece was created with this double entendre in mind. It could simply be enjoyed as a print about looking after yourself and staying positive, but on the other hand, could also be viewed as a piece inspired by drug culture. With many of Rider’s pieces having a sense of social commentary to them, I don’t doubt that this was his intentions.  

Steven Wilson

Steven Wilson is an artist, designer and animator based in Brighton. Born in London, Wilson currently works for his own self-titled business alongside Pedro Cardoso. The company works in both analogue and digital methods to create unique and colourful pieces of art. Steven Wilson has found a great deal of success since launching his company in 2001, creating work for big names such as: Nike, The Oscars, Virgin and the New York Times, amongst many others.6

‘Krunk Melts’ is a screen print, made using 3 layers, by Steven Wilson. It includes a bear, with a rather unpleased look on its face, melting away. I really liked this print because of the bright colours and unusual subject matter. Many of Steven Wilson’s work has a huge pop art style to it, and you can definitely see the correlation in this piece. The print uses a lot of bright colours, creating a cartoon style. The bear is outlined with a dark blue rather than a black, softening the piece all together. I feel that this makes the print feel a lot more comforting, compared to creating a stark contrast between the bright colours and a solid black outline. However, this carefree style is contradicted with the expression on the bear’s face. It has a very disapproving look on its face, as opposed to the stereotypical cheery smile cartoons are often given. This changed the feeling of the piece completely. The look on the bear’s face, along with the fact that it is melting, created a more sombre feeling to the print. This is strengthened with the fact that the bear itself is blue, a colour often used to convey sadness. I really liked the contrast this created. The use of bright colours in a piece that feels rather negative confuses the viewer. The art that, at first, seemed so cherry and carefree now has a sense of melancholy that was not initially obvious. I feel that this depth, mixed with the simplicity of the design, created a really interesting and effective print. After closely inspecting the piece, you are almost left not knowing how to feel about it, highlighting how powerful an image it is.  

Andy Warhol

Andy Warhol was an American artist who explored a huge selection of media such as: painting, printing and sculpture as well as photography and film. Warhol was best known for his screen prints that explored the relationship between advertisement and celebrity culture. His art boosted him to fame during the 60’s, leading to him being considered a leading artist of the pop art movement with pieces such as, ‘Campbell’s Soup Cans’ and ‘Shot Mrilyns’. 8

Giant Panda 295 is a screen print done by Andy Warhol in 1983. The piece was done as a commission by Ron and Freyda Feldman, and was one of ten pieces created inspired by endangered animals. The print included a red panda with a thin blue outline and pink and yellow details. I really liked this piece as I felt it was instantly obvious why it was created. The red and yellow together somewhat mimics a fire, creating a sense of danger and anxiety. The use of a blue outline really helps the piece stand out more, especially against the red. This choice was especially effective in the eyes of the panda. There isn't really much detail, however I feel that this colour choice makes them look a lot more unnatural. The blue against the red really helps the eyes stand out. I feel that this was done to make the view feel like the panda is looking right at them, almost as if the panda is shaming you for not helping. This small detail, along with the intense colour pallet creates a sense of urgency, almost pushing you to help the cause. I think that this was a highly successful piece, managing to capture so much emotion in such a simple print. Even without looking into the background of the piece, you can hazard a good guess as to why it was created. Proving just how powerful a print this is, highlighting Warhol’s talent as a whole.  

Screen printing inspires me for many reasons, and I feel that the more artists I research that explore the medium, the more passionate I feel about it. I really love that every artist that uses screen printing does it in their own way, with every artist’s work looking wildly different from each other's. Yet, the use of bright colours and layers ties them all together. I think throughout my journey as a printmaker, I want to experiment with screen printing more, taking into consideration how I can use both colour and layering to enhance my work.

Skinny Movie Deposition For Lift Off: Critical Basic principles

Skinny Movie Coatings are at times applied to entire surfaces of substrates, "wall to wall" so to converse, in a ongoing unbroken movie. But numerous situations the ultimate variety of no matter what specific content is currently being used is patterned so that it is coated in selected distinct parts and bare in other folks. There are two principal approaches to reach this outcome: 1. Subtractive, or Etch Back system - the overall area is coated, and then choose parts are taken off, leaving the ideal sample. The pattern generating step ordinarily entails some sort of bodily masking agent and then an suitable type of etching to take out what need to be taken off and not damage something else. 2. Additive, or Carry Off procedure - the sample creating action, which once more will generally contain some sort of actual physical masking agent, will come first. This is adopted by the coating procedure, which is comparable to using a stencil. Only the ideal sample will get applied by way of the openings in the mask on to the precise substrate. The excessive finishes up on top of the mask and is taken off when the mask is lifted off. This type of Carry Off Slim Movie Deposition course of action will be the subject of this write-up. A main consideration for deciding on a Actual physical Vapor Deposition (PVD) course of action for Carry Off is the pattern specification. If the pattern proportions and tolerances are comparatively large, a physical mask such as a slender sheet metal stencil can do the job and the process can be effectively any form. But for smaller dimensions, sharper line resolution, and tighter tolerances, the mask will most likely have to be photoresist. To accomplish thoroughly clean traces, this photoresist is generally uncovered and created to generate a destructive slope, an "overhanging" edge so that the deposition can be shadowed beneath it leaving a little gap between the edge of the coated line and the photoresist protection. There are also unique twin layer photoresists for this purpose, providing a step overhang instead of a slope. And to just take authentic edge of the capability so afforded, which can give fantastic final results in micron or lesser proportions, the deposition vapor stream should have a very long imply absolutely free path and impinge on the masked substrate perpendicular to its floor. The previous needs lower chamber pressure, typically down below 10-four torr. And the latter commonly requires a fairly lengthy throw - the length from supply to substrate. When you loved this informative article and you would like to receive more details relating to Alta definizione 2020 i implore you to visit the website. For both of these motives, Thermal Evaporation is typically the PVD method of selection. The resource is normally located in the heart of the base of a vertical cylindrical chamber. The substrate holder (usually named tooling) is a dome rotating about a vertical axis centered above the resource at a standard distance of eighteen inches or more. The dome is frequently curved, a portion of a sphere with some radius of curvature. For Elevate Off, this radius of curvature ought to be equal to the toss distance, which is the supply to substrate (dome) length. If the source ended up a genuine mathematical level resource, it would consequently be positioned at the centre of an imaginary sphere of radius R, with the real dome remaining the topmost part of claimed sphere. With process pressure normally in the ten-5 to ten-6 torr selection, the suggest no cost route - the regular distance an evaporated atom or molecule will vacation in a straight line prior to colliding with an additional gas atom or molecule - will be at minimum equivalent to R. And with the vapor particles all touring in straight strains to all factors on the dome, every a person is on a immediate radial line and will strike the surface of the dome perpendicular to the plane that would be tangent to the floor at that stage. This condition provides perpendicular incidence on the curved dome surface area, which is needed for best pattern precision - a vapor stream coming in at an angle will not deposit particularly in the center of the photoresist (mask) opening as was supposed. But substrates are virtually generally flat, which is a deviation from this excellent curved floor and thus a deviation from totally perpendicular incidence. A fantastic rule of thumb for superior precision Elevate Off patterns is to hold this angular mistake, the deviation from perpendicular vapor stream impingement on the substrate, to fewer than five levels. And, for substrates these kinds of as semiconductor wafers in typical tooling domes, the vapor stream is perpendicular at the centre of the wafer (zero angular error) and will increase toward the edges, with the utmost error becoming dependent on the wafer diameter in relation to the throw distance.
