Semiconductor Design Industry- The History and Trends 2023

The semiconductor industry is witnessing tremendous advances in digital, and analog, tools, manufacturing technology as well and materials. Chip development requires highly sophisticated and complex processes at every level, from design to manufacturing. Going forward, this process will require significant changes, from architectural design to sustainable materials and end-to-end manufacturing, to meet the growing demand for semiconductors. To achieve this, the industry is adopting the latest technologies that increase efficiency and produce highly advanced process nodes. 

Semiconductors- the heart of IoT

We are seeing significant advances in the Internet of Things (IoT), smart devices, and, more recently, 5G. To understand where these innovations are taking us and what we should expect from them, we need a basic understanding of the underlying technologies that are helping to create this new wave of innovation. With the rise of the Internet of Things (IoT) and 5G driven by semiconductor technology, the development of AI will be faster than ever. The development of semiconductor technology has been the driving force behind the increase in computing power over the past 30 years.

Semiconductors are said to account for about 50% of computer hardware costs. Based on semiconductor technology, the integration of AI computing devices into society will be more seamless and widespread. Self-driving cars are an example that use a common advanced mobile computing system with complex algorithms to process and analyze driving data.

Based on 5G communications infrastructure, artificial intelligence (AI) and machine learning use computer vision to understand surrounding situations, then plan and execute safe driving movements. This makes traveling safer, smarter and more efficient. IoT devices can turn almost any product into a smart device, from watering systems to clothing. Retail, healthcare, life sciences, consumer products, and industrial IoT are all in high demand. Future innovations will also make custom chips more accessible and make chip manufacturing more efficient and, more importantly, more sustainable.

The Internet of Things (IoT) is important to the semiconductor industry as connected devices become more and more popular over time. As the smartphone industry stagnates, the semiconductor industry must find other avenues to exploit its growth potential. Despite the challenges, IoT remains the most affordable option for the industry. IoT applications cannot function without sensors and integrated circuits, which is why all IoT devices require semiconductors.

The smartphone market, which has fueled the semiconductor industry's growth for years, has begun to stabilize. The IoT market can generate new revenue for semiconductor manufacturers and keep the semiconductor industry growing at a compound annual growth rate of 3-4% for the foreseeable future.

Process nodes in semiconductor technology measure the size of transistors and other components on the chip. The number of nodes continues to increase over the years, leading to a corresponding increase in computing power. Nodes often involve different generations of circuits and architectures.

In general, the smaller the technology node, the smaller the feature size, making smaller transistors both faster and more power efficient. This trend has allowed us to develop more powerful computers and devices in smaller form factors. There is a relationship between process nodes and CMOS transistor performance

Frequency, power, and physical size are all affected by the choice of processing node. This is why it is important to understand how the semiconductor process evolves over time. The history of semiconductor technology nodes dates back to the 1970s, when Intel released the first microprocessor, the 4004. Since then, we have seen exponential growth in power computing thanks to advances in the size of nodes in semiconductor technology. This has allowed us to create ever smaller and more powerful devices like smartphones, tablets and wearables

The Apple A15 bionic is currently at the heart of most of Apple's latest products using 7nm node technology and has nearly 4 billion functional transistors. Semiconductor nodes are a key factor in determining the performance of a microcontroller. As technology advances, the number of nodes in each microcontroller increases. This trend has been observed over the past few years and is expected to continue in the future.

A technology node (also called a process node, process technology, or simply a node) refers to a specific semiconductor manufacturing process and its design rules. Different nodes usually mean different circuit generations and architectures. In general, the smaller the technology node, the smaller the feature size, the smaller the transistor, the faster the speed, and the more energy efficient. Historically, the process node name referred to various characteristics of the transistor, including gate length and M1 half step. More recently, the number itself has lost the precise meaning it once had due to various marketing moves and disagreements between foundries.

Newer technology nodes, such as 22nm, 16nm, 14nm, and 10nm, refer only to specific generations of chips manufactured using specific technologies. This does not correspond to the length of the gate or the half step. However, the naming convention is still followed, which is how the major foundries call the buttons. Early semiconductor processes had arbitrary names, eg, HMOS III, CHMOS V.

Later, each next-generation process was called a technology node or process node, representing the gate length in terms of size. Minimum feature size of nanometer (or previously 1 micron) transistor processing, such as "90 nm process". However, things have changed since 1994 and the number of nanometers used to name process nodes has become a marketing term that has nothing to do with actual feature size or shadow density semiconductor (number of transistors per square mm).

The evolution of the technology node process: Basically, the technology node corresponds to the size of the physical characteristics of the transistor. Initially, every microcontroller was made from transistors, which are essentially switches that control the flow of electricity and allow the microcontroller to perform its logic function. Technology nodes such as 28nm or 65nm refer to the minimum data graphics specification that can be drawn on the array (half step or gate length). However, there is no standardization in naming technology nodes. The node's name like 28nm or 65nm actually comes from the minimum gate length of the transistor, as shown in a typical planar MOSFET configuration.
