From Low-Price Dumping to a Fall from Grace

Top 10 Semiconductor Manufacturers and Their Value Changes[2]

Living Off Past Glory in Materials and Equipment

The Global Semiconductor Market Pattern by Field[17]
-
Silicon wafers: High investment in production lines, high depreciation costs, volatile gross profit margins, and many long-term supply agreements (LTA). Shin-Etsu Chemical and Sumco together have maintained a market share of over 50%;[19] -
Photomasks: 45nm is a watershed; wafer fabs with processes more advanced than 45nm generally produce their own photomasks, while mature processes tend to opt for third-party photomask products for better cost. DNP, Toppan Photomask, and Hoya are three Japanese companies with significant market dominance, with SKE holding a 20.2% market share in photomasks for flat-panel displays;[20] -
Electronic special gases: These gases require extremely high purity. Taiyo Nippon Sanso holds 18% of the global market. In terms of electronic gases for semiconductor use in China, companies like Kanto Chemical, Central Glass, and Showa Denko exhibit strong dominance;[21] -
CMP materials: In CMP polishing liquids, Hitachi Chemical and Fujimi together have maintained a market share of over 20%. In CMP polishing pads, U.S. DuPont has long held over 80% market share, while Japan’s Fujibo and JSR occupy single-digit shares;[22] -
Photoresists: These are high-tech barrier materials, with complex processes and high purity requirements, and a certification cycle of 2-3 years. Tokyo Ohka Kogyo, JSR, Fujifilm, Shin-Etsu Chemical, and Sumitomo Chemical are mainstream manufacturers, and currently, only Japanese companies can produce EUV photoresists besides U.S. DuPont;[23] -
Wet chemicals: These are used in various downstream applications, have high technical barriers, rapid updates, strong functionality, and strong added value. Japanese companies hold 27% of the global market share, including Kanto Chemical, Mitsubishi Chemical, Kyoto Chemical, and Sumitomo Chemical;[24] -
Target materials: Among all industries, the target materials for semiconductors have the highest purity requirements. Nippon Mining’s market share reaches 30%, while Tosoh’s market share is 20%. In 2021, Japan’s target materials accounted for 16% of the semiconductor capacity in mainland China.[25]

Top 15 Semiconductor Equipment Suppliers in 2021[49]

Major IC Companies in Japan, Table compiled by Guokey Hard Technology

Domestic Chips Should Not Follow Japan’s Old Path
Japan’s semiconductor industry, now in the shadows, will find it challenging to regain its former glory. Experts analyze that, given Japan’s current development situation, returning to the level of the 1980s would require an investment of at least $78 billion to make up for more than 20 years of investment shortfalls, and there is no other way out.[55]
However, contrary to this, Japanese companies have always been very conservative, especially in semiconductors. Many companies have experienced severe failures, so even when receiving a large number of orders, they are reluctant to expand production, instead pursuing the goal of becoming “small and beautiful” companies.[56]
With the current downward trend in overall semiconductor demand, Japanese companies’ advantages in equipment and materials have begun to gradually weaken, and relying solely on past glories is no longer feasible. The Semiconductor Equipment Association of Japan (SEAJ) data shows that as of February 2023, Japan’s semiconductor equipment sales have declined for five consecutive months, and SEAJ predicts that Japan’s semiconductor equipment sales will drop to nearly 3.5 trillion yen this year, a decline of 5%, marking the first decline in four years.[57]
Moreover, the operational efficiency of Japanese companies has gradually declined. In the 2022 IMD World Competitiveness Yearbook, Japan’s overall competitiveness dropped from 25th in 2018 to 34th (out of 63 countries and regions). Over the past 20 years, Japanese companies’ rankings in international competitiveness have fallen from the 20s to the 30s, with operational efficiency indicators all ranking below 40.[58]

Japan’s World Competitiveness Related Data[58]
In fact, Japan’s past predicament is very similar to that of domestic semiconductors: a short-term rise followed by unreasonable suppression by the U.S. Although we cannot avoid foreign restrictions from the source, we can learn from the experience:
-
Japan lacked sensitivity to changes in production models, stubbornly adhering to a vertical production model in R&D and production, making it difficult to meet market demand. Over time, the market eliminated these Japanese products;[59]
-
Japan failed to seize market trends, not only neglecting the importance of microprocessors (CPUs), cellular mobile technology, and smartphones but also facing bottlenecks in the Japanese-style technology supremacy, leading to an increasing inability of Japanese companies to keep pace with market developments;[9]
-
Japan’s industrial chain system lacks resilience, with insufficient high-end process manufacturing capabilities, only able to produce low-end products at 40nm, creating a duality paradox with upstream competitive advantages;[3]
-
Development through closed-door methods cannot produce advanced technology; only “bringing in and going out” can enhance competitiveness;
-
The clause in the U.S.-Japan Semiconductor Agreement stating that “foreign products must account for 20% of the Japanese market share” became a lethal weapon for the U.S., continually demanding Japan to open its market, and China should also take this as a warning, recognizing the harm of related clauses and remaining vigilant against U.S. schemes.[59]
Regardless, Japan’s days of living off past glories are long gone, and domestic semiconductors should seek new strategies.
