On the mainland, the annual output of small standard 4-6 inch silicon wafers (including polished wafers and epitaxial wafers) is about 52 million, which is basically self-sufficient. However, the self-sufficiency rate of 8-inch and 12-inch silicon wafers is still very low, and there are almost no 12-inch silicon wafers. At present, the mass production of 8-inch silicon wafers and epitaxial wafers includes Zhejiang Jinruihong, Kunshan Zhongchen (Taiwan Province wafer world), Beijing Research Institute, Hebei Puxing, Nanjing Guosheng, China Electronics 46 and Shanghai Xinao, with an estimated monthly production capacity of 233,000 wafers. At present, the mainland’s demand for 8-inch monthly is about 800,000 pieces, and it is estimated that it will reach 7.5 million to 8 million pieces in 2020. Almost all 12-inch silicon wafers are imported, because there is still a shortage of self-restraint. At present, the monthly demand in mainland China is 500,000, and it is estimated that the monthly demand will reach 1.1 million to 1.3 million in 2018.
Under the normal situation of shortage and price increase, the wafer factory, which is the leading position in the shopping mall, has grabbed the silicon wafer production capacity in a colorful way, and the silicon wafer supplier is also giving priority to ensuring these big customers. For example, TSMC and UMC grabbed the silicon wafer production capacity, signed short-term and medium-term contracts with two major Japanese silicon wafer suppliers, and even heard that TSMC had negotiated a contract with the silicon wafer factory for the next two years to ensure supply, during which the increase reached 20% in 2018; Meguiar’s, Intel, Gexin, etc. have already signed contracts early to package production capacity and so on.
With regard to the new capacity offered by mainland customers in the next three years, the silicon wafer factory requires the price to jump from US$ 135, and requires to pay a large amount of guarantee money in advance. In addition to raising the business threshold for mainland semiconductor factories, it also establishes the bottom line for other semiconductor factories. If they are unwilling to accept the price of US$ 110~120, many land factories are willing to pay a higher price to package the capacity. Such a silicon wafer shopping mall with oversupply and oligopoly, the outstanding contradiction between supply and demand will force the localization of silicon wafers. The meaning of investing in building a large silicon wafer project to China’s semiconductor industry is that the upstream (raw material side) is self-controllable.
Capital contribution of silicon wafer fab in China
Different from wafer foundry, it takes at least 100,000 wafers to build a new silicon wafer factory, and the cost is 400-500 million dollars. After the silicon wafer sample comes out, it needs to be inspected and certified by light industrial chains such as wafer factory and sealing and testing factory. It is estimated that it will take 1.5~2 years to adjust the mass production after the factory is built and certified, but whether it is necessary to invest 12 inches or 18 inches now is also the key for manufacturers to consider.
According to the incomplete statistics of the micro-grid, there are at least nine silicon wafer projects in China, including Shanghai Xinsheng, Chongqing Super Silicon, Ningxia Yinhe, Zhejiang Jinruihong, Zhengzhou Hejing, Yixing Zhonghuan Jingsheng Project and Xi ‘an High-tech Zone Project. It is estimated that the planned investment exceeds 52 billion yuan, and the monthly production capacity of 12-inch silicon wafers under planning has reached 1.2 million, which can alleviate the shortage of silicon wafers in the long run. It is estimated that new players will still participate in the big silicon wafer operation in the next few years.
