What is Chiplet?

Chiplets are a new type of chip that paves the way for designing complex SoCs. Chiplets can be regarded as a high-tech version of Lego bricks. A complex function is broken down into small modules, and then there are Chiplets that can perform a single specific function very efficiently. Therefore, an integrated system using a Chiplet can include: data storage, signal processing, computation, and data flow management, building up a “Chiplet”.

A Chiplet is part of a package architecture, which can be defined as a physical piece of silicon that packages IP (intellectual property) subsystems with other Chiplets using a package-level integration approach. Chiplet technology integrates multiple electrical functions in a single package or system.

History of Chiplet

The concept of chips has been around for decades, but has gained more attention in recent years as a way to address the challenges of shrinking traditional monolithic ICs. With the continuous advancement of Moore’s Law, the size and complexity of monolithic ICs have increased significantly, resulting in higher costs and greater difficulty in manufacturing. Chiplet-based design offers a potential solution to these challenges, allowing companies to use smaller, more specialized Chiplets that can be easily combined and assembled into a complete system.

History of Chiplet

The term “Chiplet” is relatively new, having only been used for about five years or so. It was originally created by researchers and scientists at the University of Michigan when they began investigating ways to improve the design, efficiency, and functionality of computer chips. The word is a combination of “chip” and “petite”, which can be translated as “small”. So, a Chiplet is a very small computer chip used in high-tech equipment that can perform more complex tasks than traditional CPU chips. It has grown rapidly over the past few years, and many experts believe it will begin to replace traditional chipsets in consumer devices due to its enhanced capabilities.

Market prediction about Chiplet

The Chiplet market is expected to experience significant growth in the coming years. According to a report published by MarketsandMarkets, the market is expected to be worth $5.7 billion by 2025. This represents a compound annual growth rate (CAGR) of 18.9% from 2020 to 2025.

According to a report published by Transparency Market Research, the chip market is expected to be worth $47.2 billion by 2031. This represents a CAGR of 23.9% from 2021 to 2031. The forecast takes into account the growing demand for high-performance computing and data analytics, as well as the growing trend towards modularity and customization in electronic design.

These data indicate that the Chiplet market is expected to witness promising growth in the coming years. Chips are small modular chips that can be combined into larger, more complex systems-on-chip (SoCs). They offer many advantages over traditional monolithic chips, including increased performance, cost savings, and design flexibility. These factors, coupled with the growing demand for high-performance computing and data analytics, are likely to drive the growth of the chip market over the next few years.

Benefits of Chiplet and why are Chiplet better?

Chiplets offer several important advantages over traditional monolithic processor designs. They can be customized and upgraded quickly and easily, reducing development time and costs. But most importantly, Chiplets boost performance through the use of specialized processing elements optimized for specific tasks. For example, if the AI application in your device requires high processing power, you can replace the traditional CPU with a Chiplet designed for AI tasks.

In addition to these performance advantages, Chiplet can also reduce the processor’s size and power requirements. By consolidating multiple separate functions into a single unit, they eliminate the need for much of the wiring, cooling infrastructure and other components required by conventional chips. This reduces manufacturing costs and allows for smaller device designs, ideal for mobile devices such as smartphones or AR/VR headsets.

The flexibility offered by Chiplet also provides important design and development advantages. Since they can be easily customized and upgraded, Chiplets allow manufacturers to quickly adapt to changing market conditions or new technological developments. They also simplify the production process by reducing the steps required to design and manufacture a custom SoC.

Chiplet technology allows manufacturers to use smaller, more specialized Chiplets instead of individual monolithic chips for certain tasks, helping to increase yields and reduce costs. This helps improve yields because it reduces the complexity of the chip manufacturing process, which can reduce the number of defects that arise and increase the overall yield of usable chips. In addition, since the Chiplet can be individually designed and manufactured, it is easier to optimize the manufacturing process for each specific Chiplet, further increasing yield.

Another way Chiplet helps reduce costs is by allowing manufacturers to use a mix-and-match approach to creating SoCs. Instead of designing and manufacturing a new chip from scratch for each new product, manufacturers can use a combination of existing Chiplet to create the SoC they need, which can be faster and more cost-effective. This is especially useful for companies that need to bring products to market quickly and need to be able to quickly change their SoCs to meet changing market demands.

Challenges of Chiplet

Chiplets technology faces the following challenges:
The first challenge is to ensure the low cost and high reliability of the Chiplet model, which is based on advanced packaging technology. Packaging technology is the focus of Chiplets.

The second challenge is to maintain good product quality at an economical production rate. Although Chiplet is a certified product, there are still yield issues. If a problem is found in one Chiplet silicon chip in a SiP, the cost of the entire Chiplet system will be higher.

Another outstanding challenge is test coverage. Since multiple Chiplets are embedded together, each Chiplet can be connected to a limited number of pins. Some Chiplet became inaccessible outside of the pins, which caused problems with chip testing.

Standard of Chiplet

While Chiplets pose many challenges, especially in terms of commercial application and scalability, they offer a promising solution to some of today’s most pressing chip design problems. With Chiplet technology gaining momentum, it’s only natural that many of the biggest players in the industry are getting involved. GlobalFoundries and Samsung are two major companies at the forefront of this trend, each working to develop their own solutions to the chip challenge. Intel, AMD, Qualcomm, Arm, TSMC, and Samsung are collaborating to define a new standard for Chiplet-based CPUs. This gave birth to UCIe.

The promoters of UCIe (Universal Chiplet Interconnect Express) are quite large, including AMD, Arm, Intel and Qualcomm, chip factories TSMC and Samsung (and Intel), chip packaging company Advanced Semiconductor Engineering, and cloud computing providers Google, Microsoft, and Meta.

Chiplet standardization efforts have been developed to help address issues related to the performance of these connections. These include improved thermal management, lower power consumption, and reduced latency. They can also help improve the efficiency of chip-to-chip communication and integration by increasing the data traffic flowing through these connections.

One of the biggest challenges in Chiplet standardization is ensuring chips can be designed to work with a variety of interposer designs and standards. There has been some progress in this direction, including efforts by multiple organizations to write standardized specifications for the chip interface. However, as more companies adopt these types of technologies, ensuring compatibility can become increasingly difficult. Companies interested in implementing these technologies need to keep a close eye on the current state of Chiplet standardization efforts to maximize their chances of success.
