Industry First: UCIe Optical Chiplet Unveiled by Ayar Labs

Ayar Labs has unveiled the industry’s first Universal Chiplet Interconnect Express (UCIe) optical interconnect chiplet, designed specifically to maximize AI infrastructure performance and efficiency while reducing latency and power consumption for large-scale AI workloads.

This breakthrough will help address the increasing demands of advanced computing architectures, especially as AI systems continue to scale. By incorporating a UCIe electrical interface, the new chiplet is designed to eliminate data bottlenecks while enabling seamless integration with chips from different vendors, fostering a more accessible and cost-effective ecosystem for adopting advanced optical technologies.

The chiplet, named TeraPHY™, achieves 8 Tbps bandwidth and is powered by Ayar Labs’ 16-wavelength SuperNova™ light source. This optical interconnect technology aims to overcome the limitations of traditional copper interconnects, particularly for data-intensive AI applications.

“Optical interconnects are needed to solve power density challenges in scale-up AI fabrics,” said Mark Wade, CEO of Ayar Labs.

The integration with the UCIe standard is particularly significant as it allows chiplets from different manufacturers to work together seamlessly. This interoperability is critical for the future of chip design, which is increasingly moving toward multi-vendor, modular approaches.

The UCIe Standard: Creating an Open Chiplet Ecosystem

The UCIe Consortium, which developed the standard, aims to build “an open ecosystem of chiplets for on-package innovations.” Their Universal Chiplet Interconnect Express specification addresses industry demands for more customizable, package-level integration by combining high-performance die-to-die interconnect technology with multi-vendor interoperability.

“The advancement of the UCIe standard marks significant progress toward creating more integrated and efficient AI infrastructure thanks to an ecosystem of interoperable chiplets,” said Dr. Debendra Das Sharma, Chair of the UCIe Consortium.

The standard establishes a universal interconnect at the package level, enabling chip designers to mix and match components from different vendors to create more specialized and efficient systems. The UCIe Consortium recently announced its UCIe 2.0 Specification release, indicating the standard’s continued development and refinement.

Industry Support and Implications

The announcement has garnered strong endorsements from major players in the semiconductor and AI industries, all members of the UCIe Consortium.

Mark Papermaster from AMD emphasized the importance of open standards: “The robust, open and vendor neutral chiplet ecosystem provided by UCIe is critical to meeting the challenge of scaling networking solutions to deliver on the full potential of AI. We’re excited that Ayar Labs is one of the first deployments that leverages the UCIe platform to its full extent.”

This sentiment was echoed by Kevin Soukup from GlobalFoundries, who noted, “As the industry transitions to a chiplet-based approach to system partitioning, the UCIe interface for chiplet-to-chiplet communication is rapidly becoming a de facto standard. We are excited to see Ayar Labs demonstrating the UCIe standard over an optical interface, a pivotal technology for scale-up networks.”

Technical Advantages and Future Applications

The convergence of UCIe and optical interconnects represents a paradigm shift in computing architecture. By combining silicon photonics in a chiplet form factor with the UCIe standard, the technology allows GPUs and other accelerators to “communicate across a wide range of distances, from millimeters to kilometers, while effectively functioning as a single, giant GPU.”

The technology also facilitates Co-Packaged Optics (CPO), with multinational manufacturing company Jabil already showcasing a model featuring Ayar Labs’ light sources capable of “up to a petabit per second of bi-directional bandwidth.” This approach promises greater compute density per rack, enhanced cooling efficiency, and support for hot-swap capability.

“Co-packaged optical (CPO) chiplets are set to transform the way we address data bottlenecks in large-scale AI computing,” said Lucas Tsai from Taiwan Semiconductor Manufacturing Company (TSMC). “The availability of UCIe optical chiplets will foster a strong ecosystem, ultimately driving both broader adoption and continued innovation across the industry.”

Transforming the Future of Computing

As AI workloads continue to grow in complexity and scale, the semiconductor industry is increasingly looking toward chiplet-based architectures as a more flexible and collaborative approach to chip design. Ayar Labs’ introduction of the first UCIe optical chiplet addresses the bandwidth and power consumption challenges that have become bottlenecks for high-performance computing and AI workloads.

The combination of the open UCIe standard with advanced optical interconnect technology promises to revolutionize system-level integration and drive the future of scalable, efficient computing infrastructure, particularly for the demanding requirements of next-generation AI systems.

The strong industry support for this development indicates the potential for a rapidly expanding ecosystem of UCIe-compatible technologies, which could accelerate innovation across the semiconductor industry while making advanced optical interconnect solutions more widely available and cost-effective.

Use this trick to Save time : HDL Simulation through defining clock

Why is this trick useful? Defining a clock in your simulation can save you time during simulation because you don't have to manually generate the clock signal in your simulation environment. Wanted to know how to define and force clock to simulate your digital system. Normally define clock used to simulate system with clock input. But I am telling you this trick for giving values to input ports other than clock. It will help you to save time in simulation because you do not need to force values to input ports every time. Lets brief What we did - gave some clock frequency to input A, like we gave 100. Than we made Half the frequency of clock to 50 and gave it to Input B. In similar way if we have 3rd input too we goanna half the frequency again to 25 and would give to next input.

Final manifestations for Book 7?

I'm trying REALLY hard not to build up any solid expectations, because I wanna go in ~fresh~! they're already so far away from anything I thought would happen (not in a bad way, I'm just accepting that I'm on Miss Yana's Wild Ride at this point and we're seeing this thing through 'til the end, by gum). so it's nothing too major, but:

they've been handing new crying expressions out like candy lately, I want to see some delicious Malleus tears.

honestly I want everyone to cry buckets. their tears sustain me. the more Silver angst specifically I get the happier I am.

SILVER!!!! 👏 VANROUGE!!!! 👏

just let him have this. the poor boy's been through so much. let him have his big "I'm proud of you, son" moment with Lilia.

I'm 100% expecting Grim's arc (and probably whatever's going on with Crowley) to be its own episode, but a nice hook to leave us hanging on would be good!

a nice hook though, please, I don't think I can take another "Grim is attacking us! now wait eight months to find out what happens :)" cliffhanger...

some Meleanor? as a treat? just a little bit, a tiny quick flashback or something, please Twst I just, I just want to see her again. let her have a little ghost cameo like Dawnathan Knight got. Lilia and his kids are all having their big group hug or whatever and she can gently fade in to be all like

(turning asks off until I'm done playing, SEE YOU ON THE OTHER SIDE Y'ALL)

ETHO - BDUBS - GEM Designs for Season 10!

They be pirates :]

Every new smp/series I come across- i like to assign an overarching theme to it and this hc season is no different:

The mainland of Season 10 is riddled with pirates and cowboys. Each hermit is wanted of some charge, for one reason or another. As initiation, losing a life will remove that bounty and that hermit can start fresh. But becoming the last survivor, that hermit will be gifted the Treasure of the Island (whatever the reward Grian says it is 😭)

MIT engineers grow “high-rise” 3D chips

New Post has been published on https://thedigitalinsider.com/mit-engineers-grow-high-rise-3d-chips/

MIT engineers grow “high-rise” 3D chips

The electronics industry is approaching a limit to the number of transistors that can be packed onto the surface of a computer chip. So, chip manufacturers are looking to build up rather than out.

Instead of squeezing ever-smaller transistors onto a single surface, the industry is aiming to stack multiple surfaces of transistors and semiconducting elements — akin to turning a ranch house into a high-rise. Such multilayered chips could handle exponentially more data and carry out many more complex functions than today’s electronics.

A significant hurdle, however, is the platform on which chips are built. Today, bulky silicon wafers serve as the main scaffold on which high-quality, single-crystalline semiconducting elements are grown. Any stackable chip would have to include thick silicon “flooring” as part of each layer, slowing down any communication between functional semiconducting layers.

Now, MIT engineers have found a way around this hurdle, with a multilayered chip design that doesn’t require any silicon wafer substrates and works at temperatures low enough to preserve the underlying layer’s circuitry.

In a study appearing today in the journal Nature, the team reports using the new method to fabricate a multilayered chip with alternating layers of high-quality semiconducting material grown directly on top of each other.

The method enables engineers to build high-performance transistors and memory and logic elements on any random crystalline surface — not just on the bulky crystal scaffold of silicon wafers. Without these thick silicon substrates, multiple semiconducting layers can be in more direct contact, leading to better and faster communication and computation between layers, the researchers say.

The researchers envision that the method could be used to build AI hardware, in the form of stacked chips for laptops or wearable devices, that would be as fast and powerful as today’s supercomputers and could store huge amounts of data on par with physical data centers.

“This breakthrough opens up enormous potential for the semiconductor industry, allowing chips to be stacked without traditional limitations,” says study author Jeehwan Kim, associate professor of mechanical engineering at MIT. “This could lead to orders-of-magnitude improvements in computing power for applications in AI, logic, and memory.”

The study’s MIT co-authors include first author Ki Seok Kim, Seunghwan Seo, Doyoon Lee, Jung-El Ryu, Jekyung Kim, Jun Min Suh, June-chul Shin, Min-Kyu Song, Jin Feng, and Sangho Lee, along with collaborators from Samsung Advanced Institute of Technology, Sungkyunkwan University in South Korea, and the University of Texas at Dallas.

Seed pockets

In 2023, Kim’s group reported that they developed a method to grow high-quality semiconducting materials on amorphous surfaces, similar to the diverse topography of semiconducting circuitry on finished chips. The material that they grew was a type of 2D material known as transition-metal dichalcogenides, or TMDs, considered a promising successor to silicon for fabricating smaller, high-performance transistors. Such 2D materials can maintain their semiconducting properties even at scales as small as a single atom, whereas silicon’s performance sharply degrades.

In their previous work, the team grew TMDs on silicon wafers with amorphous coatings, as well as over existing TMDs. To encourage atoms to arrange themselves into high-quality single-crystalline form, rather than in random, polycrystalline disorder, Kim and his colleagues first covered a silicon wafer in a very thin film, or “mask” of silicon dioxide, which they patterned with tiny openings, or pockets. They then flowed a gas of atoms over the mask and found that atoms settled into the pockets as “seeds.” The pockets confined the seeds to grow in regular, single-crystalline patterns.

But at the time, the method only worked at around 900 degrees Celsius.

“You have to grow this single-crystalline material below 400 Celsius, otherwise the underlying circuitry is completely cooked and ruined,” Kim says. “So, our homework was, we had to do a similar technique at temperatures lower than 400 Celsius. If we could do that, the impact would be substantial.”

Building up

In their new work, Kim and his colleagues looked to fine-tune their method in order to grow single-crystalline 2D materials at temperatures low enough to preserve any underlying circuitry. They found a surprisingly simple solution in metallurgy — the science and craft of metal production. When metallurgists pour molten metal into a mold, the liquid slowly “nucleates,” or forms grains that grow and merge into a regularly patterned crystal that hardens into solid form. Metallurgists have found that this nucleation occurs most readily at the edges of a mold into which liquid metal is poured.

“It’s known that nucleating at the edges requires less energy — and heat,” Kim says. “So we borrowed this concept from metallurgy to utilize for future AI hardware.”

The team looked to grow single-crystalline TMDs on a silicon wafer that already has been fabricated with transistor circuitry. They first covered the circuitry with a mask of silicon dioxide, just as in their previous work. They then deposited “seeds” of TMD at the edges of each of the mask’s pockets and found that these edge seeds grew into single-crystalline material at temperatures as low as 380 degrees Celsius, compared to seeds that started growing in the center, away from the edges of each pocket, which required higher temperatures to form single-crystalline material.

Going a step further, the researchers used the new method to fabricate a multilayered chip with alternating layers of two different TMDs — molybdenum disulfide, a promising material candidate for fabricating n-type transistors; and tungsten diselenide, a material that has potential for being made into p-type transistors. Both p- and n-type transistors are the electronic building blocks for carrying out any logic operation. The team was able to grow both materials in single-crystalline form, directly on top of each other, without requiring any intermediate silicon wafers. Kim says the method will effectively double the density of a chip’s semiconducting elements, and particularly, metal-oxide semiconductor (CMOS), which is a basic building block of a modern logic circuitry.

“A product realized by our technique is not only a 3D logic chip but also 3D memory and their combinations,” Kim says. “With our growth-based monolithic 3D method, you could grow tens to hundreds of logic and memory layers, right on top of each other, and they would be able to communicate very well.”

“Conventional 3D chips have been fabricated with silicon wafers in-between, by drilling holes through the wafer — a process which limits the number of stacked layers, vertical alignment resolution, and yields,” first author Kiseok Kim adds. “Our growth-based method addresses all of those issues at once.” 

To commercialize their stackable chip design further, Kim has recently spun off a company, FS2 (Future Semiconductor 2D materials).

“We so far show a concept at a small-scale device arrays,” he says. “The next step is scaling up to show professional AI chip operation.”

This research is supported, in part, by Samsung Advanced Institute of Technology and the U.S. Air Force Office of Scientific Research.
