Since the beginning of this year, the price of silicon wafers, one of the key materials in the semiconductor industry, has been rising, and the price increase trend is rapidly spreading from 12-inch wafers to 8-inch and 6-inch. According to another report, leading companies such as TSMC and UMC have signed short-term and medium-term contracts with major suppliers of silicon wafers such as ShinEtsu and SUMCO, and the 12-inch wafer signing price has been increased to The film is $120, up 60% from $75 at the end of last year. Silicon wafers have always been a shortcoming in China's semiconductor industry chain. At present, domestic enterprises can only meet the performance requirements of 4-6 inch silicon wafers, and supply a small amount of 8-inch market. The 12-inch silicon wafers are basically blank. At a time when the market supply is sufficient, this state may not have a major impact on the entire downstream industry. However, once supply and demand are unbalanced, some new domestic wafer fabrication companies or small and medium-sized fabs in the future may fall into the embarrassing situation that capacity is available but no wafers are available. Therefore, it is imperative to increase the localization rate of silicon wafers. The gap between supply and demand will continue to expand. The chip is fabricated on the basis of silicon wafers. Therefore, the silicon wafer industry is not the foundation of the integrated circuit industry. However, the supply of wafers around the world has continued to be tight this year, and there has been a continuous rise in prices for eight years. According to the silicon wafer industry analysis report released by SEMI, the global wafer shipment area in the second quarter of this year was 2978 million square inches, and the shipments for five consecutive quarters reached a record high. Zhao Rongxiang, deputy general manager and spokesperson of Taiwan-based silicon wafer manufacturer Taishengke, whose parent company is SUMCO, said that this year, silicon wafers will be in short supply and prices will continue to rise, and the supply and demand situation of the market will be predicted from 2018 to 2019. Will be even more nervous. As the capacity of new fabs in mainland China will be opened, demand is expected to rise further. With the simultaneous increase in silicon wafer capacity, supply will be tighter than it is now. Zhao Rongxiang expects that the wafer wafer market will grow by 4.3% to 5.4% from 2017 to 2020, with NAND FLASH and logic wafers being the main drivers. The main reasons for the continued rise in silicon wafer prices in recent months: First, the silicon wafer industry has experienced many years of low tide, and excess capacity has been digested. At present, the production capacity of the world's major silicon wafer manufacturers has been fully opened but still unable to To meet the demand for orders, production capacity continues to be tight. Secondly, China has vigorously supported the development of the semiconductor industry, and the process of localization of chips has accelerated. Under the guidance of the policy, the investment in the 12-inch fab has surged. The current monthly production capacity is about 460,000 pieces, and the capacity under construction is about 630,000 pieces. In the future, China's 12-inch factory will have a monthly production capacity of 1.09 million units, which will deepen the supply and demand gap of silicon wafers. In addition, the increase in shipments of consumer electronics such as smartphones has led to further recovery of the semiconductor industry downstream of silicon wafers, which is the underlying cause of this shortage of silicon wafers. In response to the above situation, Liang Junwu, an academician of the Chinese Academy of Engineering and a researcher at the Institute of Semiconductors of the Chinese Academy of Sciences, pointed out at the "China Qujing First Silicon Crystal Materials Forum" held recently that integrated circuits and power semiconductors are strategic industries in which advanced powers compete, and electronic grade polysilicon is Develop the foundation of the integrated circuit industry. Although China has become a major producer of solar grade polysilicon, China's strength in electronic grade polysilicon is still insufficient. Therefore, the next stage of China's main task is to complete the electronic grade polycrystalline silicon-single-crystal silicon that meets the needs of IC and power electronic device industry with high quality, and vigorously promote the development of China's domestic silicon wafer industry with all links of its related industry chain. There is no time to delay. 12-inch silicon is basically blank. From a global perspective, the silicon wafer industry has a high monopoly. More than half of the world's production capacity is concentrated in Japan, and the larger the size and purity of the silicon wafer, the more serious the monopoly situation. According to statistics, the top two global semiconductor wafer sales in 2015, Shin-Etsu and Sumco are Japanese companies. Among them, Shin-Etsu’s sales in 2015 exceeded US$2.1 billion, Sumco’s sales reached nearly US$2 billion, and the two Japanese companies’ market share totaled more than 50%. Germany's Siltronic (ranked third in the world) had sales of nearly $1.05 billion in 2015, and SunEdison Semiconductor, LG Siltron and Global Wafer, ranked fourth to sixth, had sales between $700 million and $800 million. Other companies have sales below $300 million. From this set of data, we can see that the monopoly of the entire industry is high. The sales share of the top six factories reached 92%. In comparison, the gap in China's silicon wafer industry is still very large. According to Yuan Tong, executive deputy secretary-general of China Electronic Materials Industry Association, in 2016, domestic enterprises produced about 52 million pieces of 4-6 inch silicon wafers (including polished sheets and epitaxial wafers), which can basically meet domestic 4-6. Inch wafer requirements. With the production capacity of 8-inch silicon wafers and epitaxial wafers, Zhejiang Jinrui, Kunshan Zhongchen (Taiwan Universal Wafer Subsidiary), Beijing Research Institute, Hebei Puxing, Nanjing Guosheng, China Electronics 46 and Shanghai Xinao, total The monthly production capacity is 233,000 pieces/month. In 2016, the domestic 8-inch wafer production (including polishing and epitaxial wafers) totaled 1.2 million. At present, the domestic demand for 8-inch silicon wafers is about 800,000 pieces. From 2020, the monthly demand is about 7.5 million to 8 million pieces. The gap between supply and demand is enormous. As for 12-inch silicon wafers, they have always relied on imports. At present, the total domestic demand is about 500,000 pieces/month, and the total demand is expected to be 1.1 million to 1.3 million pieces/month after 2018. At present, China does not have the production capacity of 12-inch silicon wafers. In this regard, Yuan Tong further pointed out: "In 2016, the situation of serious surplus of low-end products in the main material industry of integrated circuits has been improved, and medium and high-end products have begun to emerge. However, how to promote the mass production of high-end products and improve the quality stability of products. Consistency with batches is a common problem faced by the industry. Concentrating industry forces to overcome the technical difficulties of 12-inch silicon wafers and realizing industrialization is imminent. " Promoting the overall coordinated development of the industrial chain " The main reason why China's 12-inch silicon wafers have been dependent on imports At present, there is no high-purity large-wafer technology for large-scale mass production of IC integrated circuits in China. The technical obstacles for manufacturing high-purity large silicon wafers are mainly the purity of silicon and the yield of large-size silicon wafers. The semiconductor monocrystalline silicon wafer needs to have a purity of 11 or more (ie, 99.999999999%), which is currently not possible in China. At the same time, large-sized silicon wafers require high processing methods such as chamfering and precision grinding, and there is no domestic Master the technical ability of high yield." Yuan Tong told reporters. Therefore, the development of the silicon crystal industry should start from the upstream, starting from the electronic grade polysilicon material, to achieve high purity of the product, and then promote the coordinated development of the industrial chain of silicon crystal materials, crystal pulling, slicing, cleaning, polishing and so on. According to the data, there are 4 to 5 enterprises engaged in the research and development of electronic grade polysilicon materials in China, mainly including the new energy company of Qinghai Yellow River upstream electronic grade polycrystalline hydropower development Co., Ltd., Yunnan Metallurgical Yunxin Silicon Material Co., Ltd., Jiangsu Xinhua Semiconductor Materials Technology Co., Ltd., Luoyang Zhongsi High-tech Co., Ltd., etc. The Yellow River Hydropower and Cloud Silicon Materials have a production capacity of 2,200 tons and a production capacity of more than 200 tons. At present, only the Yellow River hydropower and cloud core silicon materials have entered the certification and trial of silicon materials, but the quality of electronic grade products has not fully reached the international high-end product level, and the product quality stability needs to be further improved. The cost of electronic grade polysilicon remains to be seen. Further decline. However, according to Bai Ronglin, chairman of Yunnan Metallurgical Cloud Core Silicon Co., Ltd., the localization of electronic grade polysilicon is facing a rare development opportunity. "At present, the demand for silicon materials for integrated circuits in China is expanding. The number of 6-inch to 12-inch wafer production lines under construction or planned to be built in China will reach 44. After the whole production, the annual demand for domestic electronic grade polysilicon will increase to about 6,000 tons. This has provided a market foundation for the development of the industry. In the past ten years, through the introduction, digestion, absorption, integration and innovation of foreign technology, Chinese enterprises have also formed mature knowledge of hydrogenation, rectification, reduction and tail gas recovery. The technology of property rights has trained a large number of professionals, and the key equipment for polysilicon production such as reduction furnace, hydrogenation furnace and straight pull furnace has been localized. These have laid a solid foundation for improving the quality of electronic grade polysilicon and reducing manufacturing costs. Cloud core silicon products meet the requirements of 3 inch to 6 inch silicon wafers, and the performance has reached the level of imported raw materials. It has achieved continuous and stable supply, and 8 inch to 12 inch silicon wafers are being tested," Bai Ronglin said. With the breakthrough in the localization of electronic grade polysilicon, China has made progress in the field of large silicon wafers. It is reported that Shanghai Xinsheng Semiconductor expects to complete the first phase of production at the end of 2017. It plans to produce 150,000 pieces of 12-inch silicon wafers per month. By 2020, the second phase of production will be put into production, with a planned monthly production of 300,000 pieces. China's silicon wafer industry is in the process of overall promotion. In order to achieve breakthrough progress, it is necessary to promote the overall synergy of the industry chain.
