The competition pattern is relatively stable. Although the share of Japanese enterprises in the semiconductor equipment industry is decreasing, Japanese enterprises still maintain a dominant position in some other segments of semiconductor industry and semiconductor materials. The main producers in DRAM field are Samsung, Hynix and micron (including the original Japanese Elpida acquired); the NAND field is Toshiba (a four day factory jointly invested with SanDisk), Samsung and micron; the semiconductor manufacturing equipment is Tel, screen, Hitachi high tech, etc.; the semiconductor materials are JSR, tok, shinyue, etc.; the wafer has shinyue, sumco, etc.


 
Two, the development status of semiconductor material industry in Japan
There are 19 kinds of necessary materials needed to produce semiconductor chips, and most of them have very high technical barriers. Therefore, semiconductor material enterprises play an important role in the semiconductor industry. And Japanese enterprises occupy 50% or more shares in 14 important materials, such as silicon wafer, synthetic semiconductor wafer, mask, photoresist, pharmaceutical industry, target material, protective coating film, lead frame, ceramic plate, plastic plate, tab, COF, welding wire, packaging material, etc. the Japanese semiconductor material industry has maintained an absolute advantage in the world for a long time.

As the world's largest semiconductor material producer, in 2014, Japan's domestic semiconductor material consumption accounted for 22%, and Japan is also the world's leading semiconductor material exporter. Most semiconductor materials are exported to other countries in the Asia Pacific region. At present, although the semiconductor industry has started the third transfer, and gradually transferred to China based areas with more production advantages, the production capacity of supporting semiconductor materials in China needs to be improved.

3、 Development history of major Japanese semiconductor material enterprises
Semiconductor materials provide raw materials for chip manufacturing and packaging testing in the semiconductor industry chain. According to its position in the industrial chain, it can be divided into two categories: wafer manufacturing materials and packaging materials. In 2015, the total output value of the global semiconductor market was US $43.4 billion, and the materials for wafer manufacturing and packaging were US $24.1 billion and US $19.3 billion, respectively. According to the industrial chain process, semiconductor materials can be divided into wafer manufacturing materials and packaging materials.

1. Representing the development process of advanced silicon industry in Japan
As a model of "domestic technology" of Japanese silicone industry, shinyue chemical also represents the development of the whole Japanese silicon industry. Specifically, the development of sinyue chemistry mainly includes four stages.
 
The first stage: basic research and industrialization (1941-1953)
After the Second World War, Japan began to contact the organosilicon industry in the United States. Toshiba, sinyue chemical and Shimadzu started to develop the industrial technology of organosilicon. In 1952, Xinyue Chemical Co., Ltd. completed the monomer model test by the direct method of powder contact and mixing. The silicone products began to enter the market, and the Japanese silicone industry began to transition to industrialization.
 
The second stage: high speed development stage (1953-1966)
In 1953, Xinyue chemical obtained the use right of direct law patent holder & mdash; General Electric Company (GE) of the United States; in 1954, the company obtained the subsidy of silicon rubber industrialization from Japan's Ministry of general industry; in 1957, the company signed a special use right agreement with DC company for related products; in 1960, the company began to produce 1960 high-purity silicon, vinyl acetate monomer, polyvinyl alcohol, the company has Silicon machine business is on the right track. With the aid of the government's industrial subsidies, the company vigorously carried out research and development work, independently developed new silicone rubber products such as polyurethane vinegar foam stabilizer with new structure, addition molding liquid silicone rubber and so on, which improved the company's market share. In March 1960, the sales volume of organosilicon products of Xinyue chemical company exceeded 100 million yen for the first time. Since then, Xinyue chemical company's organosilicon monomer productionAt present, photoresist is the core material representing the development level of the whole semiconductor industry, which has the index function.

4、 Inspiration from the development of semiconductor materials industry in Japan to China
（1） Research on national basic research through the integration of industry, government and learning
In the early stage of development, China's semiconductor material industry can be overtaken by introducing foreign advanced technology, but in the long run, it is still necessary to learn the principle of independent research and development and independent production of Japanese semiconductor enterprises. Led by the government, all enterprises and research institutions jointly research, tackle large-scale basic research projects, develop key technologies, expand the proportion of semiconductor materials with independent intellectual property rights, and provide a platform for the development of enterprises in the industry. After each enterprise cooperates to develop key technologies, each enterprise will be commercialized.
 
（2） Identify core products with high added value to avoid product dispersion
In terms of the current global semiconductor industry, DRAM is the main product in South Korea, while American companies focus on MPU, DSP or MCU products, while Japanese companies generally produce 4-6 major products, lacking competitive core products. In terms of the semiconductor material industry, Japan's well-developed semiconductor material enterprises are basically their own fist products. After years of continuous investment in research and development of these products, the technical level of the industry is leading, ensuring the market share and market position of each enterprise.
 
（3） Actively carry out overseas R & D and cooperative R & D
In the 1980s, Japanese semiconductor manufacturers set up R & D bases in foreign countries, and established a good trust relationship with large users in the United States through joint development. However, in the late 1990s, with the decline of industry prosperity, Japanese semiconductor enterprises began to integrate and withdraw foreign R & D bases. On the one hand, the technology level began to be overtaken by emerging markets, on the other hand, the trust relationship with major customers in the United States was also damaged, which further reduced the international market share of Japanese semiconductor enterprises. However, Japanese semiconductor material enterprises have always maintained the fine tradition of overseas R & D and cooperative R & D, maintained the technological leadership and trust relationship, so Japanese semiconductor material enterprises still occupy a large share of the international market.
 
（4） Timely transformation of business model
Japanese semiconductor companies used to adopt IDM mode in the past, but after entering the 1990s, fabless + foundry mode is more suitable for the development of semiconductor industry in the world, while Japan did not transform from traditional IDM mode to light-duty mode in time.
Figure 24 development process of semiconductor business model

&Japan's semiconductor enterprises have a long industrial chain, which not only includes complete machine production and equipment production, but also involves the production of supporting components and parts. Although this mode has the advantages of supporting production, meeting the diversified needs of customers has become the focus of competition, and the specialization of semiconductor industry has become the development trend. After entering the 90s, the traditional IDM can not quickly respond to customer needs, showing a competitive disadvantage. Therefore, China's semiconductor enterprises should fully learn from the experience of Japan in the s, find a suitable business model, and carry out a thorough and powerful business model transformation in time with the development of the times.
