[News] Chip Supply in Shortage, SEMI Calls for Standardization in Back-end Processes

As TSMC and other major chip manufacturers compete for AI business opportunities, chip production capacity is unable to keep up with demand. Industry sources cited in a report from NIKKEI claimed that the slow expansion of high-end chip production capacity is due to different packaging and testing technologies used by various companies and calls for the industry to standardize as soon as possible.

Jim Hamajima, President of the Japan office of the Semiconductor Equipment and Materials International (SEMI), recently stated in an interview with NIKKEI that leading chip manufacturers like Intel and TSMC should adopt international standards for back-end processes to effectively and quickly increase production capacity.

Hamajima further noted that each company is trying to apply unique solutions in back-end processes, with TSMC and Intel using different technical standards, which leads to inefficiencies.

Semiconductor manufacturing is divided into two major parts: front-end and back-end processes. While the photolithography technology used in front-end processes widely adopts international standards set by SEMI, packaging and testing in back-end processes vary among manufacturers. For example, TSMC uses CoWoS technology for advanced packaging, while Samsung Electronics uses I-Cube technology.

In recent years, chip manufacturers have actively invested in the development of advanced packaging technologies, primarily because front-end processes face technical bottlenecks, making back-end processes the key to gaining a competitive edge.

Hamajima believes that the current state of back-end processes in the semiconductor industry is “Balkanized,” with each company adhering to its own technologies, leading to a fragmented industry. He warns that this issue will start to impact profit margins as more powerful chips are produced in the future.

Hamajima stated that if semiconductor manufacturers adopt standardized automated production technologies and material specifications, it will be easier to acquire manufacturing equipment and upstream material supplies when expanding production capacity.

Hamajima is a director of a recently launched consortium led by Intel and 14 Japanese companies to jointly develop automated systems for back-end processes. The collaborating companies include Japanese companies such as Omron, Yamaha Motor, Resonac, and Shin-Etsu Polymer, a subsidiary of Shin-Etsu Chemical Industry.

Hamajima noted that Japan, with its numerous automation equipment and semiconductor material suppliers, is an ideal location to test international standards for back-end processes.

He also acknowledged that currently, Intel is the only multinational chip manufacturer in the alliance, which might lead to the development of technical standards that favor Intel. However, he emphasized that the alliance welcomes other chip manufacturers to join, and the research outcomes will serve as a reference for future industry standard-setting.
