Summary of TSMC

Taiwan Semiconductor Manufacturing Company, Ltd. (TSMC) is the world’s largest semiconductor foundry headquartered in Taiwan. As a specialized foundry manufacturer that only manufactures semiconductors, TSMC is responsible for the manufacture of semiconductors for device manufacturers around the world.
In 1987, Morris Chang, the founder of TSMC, established TSMC, the industry’s first dedicated foundry, at the request of the Taiwanese government. At the time, the semiconductor industry was dominated by vertically integrated device manufacturers (IDM), in which a single company handled everything from design to manufacturing and sales. However, the huge capital investment required to build a semiconductor manufacturing plant (fab) in this IDM structure stifled innovation by engineers with great ideas for circuit design and advanced architecture. Mr. Chang recognized this problem and decided that by separating the design and sales of chips from the manufacturing of chips and making each a specialized business (horizontal division of labor), he could develop both these companies and the semiconductor industry. Thus, TSMC became a pioneer in the horizontal division of labor as a foundry specializing in manufacturing, and became a central player in the now mainstream business model of the horizontal division of labor in semiconductors.
 TSMC manufactures 12,302 products using 291 different technologies for 535 customers as of 2021. Its customers include many of the world’s leading logic IC manufacturers, such as Qualcomm, AMD, and Nvidia, and Japanese companies Sony and Renesas have also outsourced the manufacture of some of its products. TSMC’s high level of manufacturing technology has not allowed other foundry manufacturers to follow suit, with TSMC alone accounting for 53% of the foundry market share in fiscal year 2021.

TSMC’s connection with Japan

TSMC’s ties to Japan began with the establishment of its Japanese subsidiary in 1997, and the company has established various bases up to the present. The names of the bases and the year of establishment are as follows

1997年:TSMC Japan, a Japanese subsidiary, is established.
2019年:TSMC Japan Design Center and TSMC Design Technology Japan Corporation established
2019年:Established the System Design Center (a.k.a. d.lab) in partnership with the University of Tokyo
2021年:TSMC Japan 3DIC R&D Center established
2021年:Japan Advanced Semiconductor Manufacturing eatablished
2022年:Establishment of Osaka base office of TSMC Japan Corporation (planned)

 Takuya Yasui, the director of the TSMC Japan Design Center, commented on the role played by the TSMC Japan Design Center.

TSMC Design Technology Japan is located in the Minato Mirai district of Yokohama and was established in January 2020. The role of the company is to support customers using 5nm, 3nm and beyond state-of-the-art processes by working as one team with the Taiwan headquarters and 7 design centers around the world. Specifically, the role will be to contribute to the development of design platforms by taking charge of block design using standard cells, SRAM memory, and the latest automated placement and routing tools, as well as the creation of design environments.

 The mission of the System Design Center (a.k.a. “d.lab”) is described in the University of Tokyo’s news release accompanying the establishment of the center as follows

A dedicated area-specific chip, in which unnecessary circuits are eliminated to focus on a specific area, can improve energy efficiency by an order of magnitude compared to a general-purpose chip. This is why IT companies around the world are embarking on the development of their own semiconductors. It is necessary to design the entire system and then translate this into an advanced semiconductor device.
However, it is not uncommon for the development of a specialized, domain-specific chip to take more than a year and involve several hundred people. Therefore, it is necessary to change chip development from the traditional capital-intensive approach to a knowledge-intensive approach. Creating knowledge-intensive chip design methods is an important mission of d.lab.

Background of JASM Establishment

Attraction of TSMC by the Japanese Government

Our modern lives are supported by digital services and industries such as AI, robots, smartphones, PCs, and cloud computing. In such a society, semiconductors are key components that can be regarded as its heart.
 The shortage of semiconductors caused by various factors in recent years has had a major impact on manufacturing in industries that use semiconductors. This has made the stable procurement of semiconductors a challenge. In addition, the growing importance of semiconductors as a strategic material, essential in a wide range of industries, against a background of national conflicts, has led to calls for the strengthening of the domestic semiconductor supply chain from an economic security perspective.
 The semiconductor supply chain consists mainly of the manufacturing equipment, materials, and device industries. Japan is strong in the manufacturing equipment and materials industries and boasts a high global market share. On the other hand, in the device sector, there are still players in Japan that can compete in the global market in memory, sensors, and power devices, or foreign companies already have manufacturing bases in Japan, but Japan lags behind in logic semiconductor manufacturing technology. Most of Japan’s logic semiconductor manufacturing technology is pre-40nm process technology and does not have the capacity to manufacture advanced logic semiconductors in the 20nm range and beyond. In other words, the supply chain can be made more robust by filling in the missing manufacturing base for advanced logic semiconductors in Japan’s domestic semiconductor industry.
 However, manufacturing advanced semiconductors requires not only specialized equipment but also manufacturing process know-how, and building this know-how requires considerable time. This is why we decided to attract TSMC, which already has mature manufacturing technology and know-how in advanced logic semiconductors, with government assistance.

 The above is a brief summary of items related to the attraction of TSMC in the semiconductor strategy of the Ministry of Economy, Trade and Industry’s Semiconductor and Digital Industry Strategy Study Council.

Certified Specific Semiconductor Production Facility Development Plan; Ministry of Economy, Trade and Industry

 The “Certified Specific Semiconductor Production Facility Development Plan” was established by the Minister of Economy, Trade and Industry for the purpose of providing subsidies and other new measures to certified businesses that produce specific semiconductors. Logic semiconductors and memory semiconductors fall under the category of specified semiconductors, and the following specific conditions are set. In addition, the plan to be certified requires continuous production for 10 years or more and increased production when demand is tight.

 The grants will be made from a specific semiconductor fund totaling 617 billion yen placed at the New Energy and Industrial Development Organization (NEDO). Of this amount, a maximum of 476 billion yen will be granted to JASM, with the remainder of 92.93 billion yen going to the joint venture between Kioxia and Western Digital, and 46.47 billion yen to Micron Memory Japan.

Sony’s Investment and Aim

 On February 15, 2022, TSMC and Sony Semiconductor Solutions Corporation (“SSS”) jointly announced that they will acquire less than 20% of JASM by investing approximately US$500 million (approximately 57 billion yen*) in capital. Mr. Terushi Shimizu, President and CEO of SSS, commented on the announcement:

As the global semiconductor shortage continues, we hope that this partnership with TSMC will contribute to the stable procurement of logic wafers not only for our company, but for the entire industry. We believe that further strengthening and deepening our partnership with TSMC, which possesses the world’s most advanced semiconductor production technology, will be of great significance to the Sony Group.

 Mr. Shimizu, CEO of SSS, cited three objectives for the investment in JASM: “stable procurement of logic semiconductors,” “strengthening technical collaboration with TSMC,” and “contribution to strengthening the supply chain in Japan.
 The stacked CMOS image sensor (hereinafter referred to as “CIS”), SSS’s mainstay product, consists of two layers: a pixel section that captures light and converts it into electrical signals, and a logic circuit section that converts the electrical signals into digital information and processes the information. The investment in JASM and the production of CISs are expected to solve the problem of “stable procurement of logic semiconductors”. The investment in JASM and its manufacturing are believed to be aimed at solving the issue of “stable procurement of logic semiconductors.
