National Silicon Industry Group

National Silicon Industry Group, commonly abbreviated as NSIG, is a Chinese semiconductor materials company headquartered in Shanghai. Its principal business is the development, manufacture, and sale of semiconductor wafers, placing it in the upstream portion of the integrated-circuit supply chain. Semiconductor wafers are the highly engineered silicon substrates on which integrated circuits and other semiconductor devices are fabricated, so wafer suppliers are strategically important to chip manufacturers even though they do not generally design or produce finished chips themselves. NSIG was established in December 2015 with support from government-related and industry institutions, including the Shanghai Municipal People's Government, the China Integrated Circuit Industry Investment Fund, and Semiconductor Manufacturing International Corporation. Its formation reflected China's broader effort to strengthen domestic capabilities across the semiconductor supply chain and reduce dependence on imported materials and equipment. The company subsequently pursued international expansion rather than limiting its activities to the mainland Chinese market. A major early step was the 2016 acquisition of Okmetic, a Finnish producer of silicon wafers. The transaction gave NSIG access to an established overseas wafer business and expanded its technical and manufacturing footprint in Europe. In the same year, NSIG acquired a 14.5% interest in Soitec, a French semiconductor-materials company. NSIG later reduced that holding, but the investment demonstrated its interest in strategic international relationships within advanced semiconductor materials. NSIG became a publicly traded company on 20 April 2022, when it completed an initial public offering on the Shanghai Stock Exchange's STAR Market. The offering raised approximately $341 million according to the cited reference material, and the company's shares rose by more than 180% on their first trading day. The listing provided a public financing platform during a period in which semiconductor materials were receiving substantial policy and investor attention in China. In May 2022, NSIG announced plans to invest approximately $408.6 million in a production plant in Finland, with Okmetic responsible for the project. The planned investment reinforced the group's international manufacturing strategy and its reliance on Okmetic as an important operating subsidiary. NSIG's business scope is therefore best understood as semiconductor wafer production and related silicon-material activities, supported by a combination of Chinese state-linked capital, public-market financing, and overseas operating assets. The available reference material identifies NSIG as China's largest domestic producer of semiconductor wafers. It does not provide enough information to establish a complete current executive roster, detailed product specifications, revenue history, or a current corporate website. NSIG is treated here as an active, partially state-owned corporate brand whose principal identity is its role in semiconductor wafer manufacturing and the development of China's semiconductor-materials capabilities. National Silicon Industry Group (NSIG), known in Chinese as 沪硅产业 or 硅产业集团, is a commercial group focused on the semiconductor silicon-materials industry and its ecosystem. Its official website identifies the company as 上海硅产业集团股份有限公司 and describes its ambition to build a global semiconductor-materials group and an internationally competitive, one-stop semiconductor-materials service platform. The company says it intends to combine organic growth with investment, mergers and acquisitions, and international cooperation to strengthen the competitiveness of China’s semiconductor silicon-wafer industry and support the foundations of the integrated-circuit sector. The group’s portfolio and industrial layout include large-diameter silicon wafers, SOI wafers, and customized silicon wafers. Its website presents Shanghai Xinsheng as having achieved scaled sales of 300 mm wafers, with some products certified by major domestic semiconductor customers. Xinao focuses on SOI and the development of a high-end domestic SOI production line. Okmetic is described as a major global supplier of MEMS wafers, specializing in customized, high-value-added products and possessing 200 mm wafer mass-production capability. The site also identifies Soitec as an equity-investment and strategic-cooperation partner, rather than presenting it as a wholly owned subsidiary. The official site lists subsidiaries including Shanghai Xinsheng, Taiyuan Jinke, Okmetic, Xinao Technology, Xinao Xinyi, and Xin Silicon Polymer, as well as participating companies including Soitec, Jicaiyuan, and Xinruiguang. These names indicate a portfolio spanning wafer manufacturing, specialized materials, and related semiconductor activities. The company’s stated global orientation and its international cooperation are reflected in the presence of Okmetic and its strategic relationship with Soitec. The company’s official leadership page identifies Jiang Haitao as chairman from August 2025, Qiu Ci Yun as director and president, and other group executives responsible for operations, finance, and subsidiary businesses. The supplied official-site material does not establish a founding date, headquarters address, ownership structure, or stock-listing details, so those particulars are not asserted here. NSIG became a publicly traded company on 20 April 2022, when it completed an initial public offering on the Shanghai Stock Exchange's STAR Market. The offering raised approximately $341 million according to the cited reference material, and the company's shares rose by more than 180% on their first trading day. The listing provided a public financing platform at a time of heightened policy and investor attention to China's semiconductor materials sector. In May 2022, NSIG announced a plan to invest approximately $408.6 million in a new production plant in Finland, with Okmetic designated to take responsibility for the project. The group's portfolio and industrial layout include large-diameter silicon wafers, SOI wafers, and customized silicon wafers.

The homepage's latest-news area reports a globalization initiative and an investment of nearly RMB 3 billion to accelerate capacity expansion for 200 mm specialty silicon wafers. The company's official leadership page identifies Jiang Haitao as chairman from August 2025, Qiu Ci Yun as director and president, and describes other group executives responsible for operations, finance, and subsidiary businesses. Qiu Ci Yun has served as group president since April 2020. Kai Seikku has been president and a director of Okmetic since 2010, became a group executive vice president in March 2019, and is described as serving as a Soitec director since 2019. Li Wei became group executive vice president and board secretary in March 2019, then group executive vice president in September 2024. Chen Taixiang became group executive vice president in September 2024. Li Wei is also described as having served as vice president from the establishment of Shanghai Silicon Industry Investment Co. in December 2015. NSIG is described in the reference material as China's largest domestic semiconductor-wafer producer. Its development has therefore combined state-linked founding support, acquisitions of overseas wafer and materials businesses, strategic equity investment, and public-market financing. The available material does not establish a detailed chronology of production volumes, a complete list of wafer types, or the identities of all current and former senior executives. Those areas remain open for further verification.

National Silicon Industry Group was founded in December 2015 as part of China's effort to develop a stronger domestic semiconductor industry. The company was established with participation from government-related entities and major industry institutions, including the Shanghai Municipal People's Government, the China Integrated Circuit Industry Investment Fund, and Semiconductor Manufacturing International Corporation. Its core business became the development and sale of semiconductor wafers, an upstream activity essential to integrated-circuit production. NSIG pursued an international growth strategy soon after its formation. In 2016, it acquired Okmetic, a Finnish semiconductor-wafer producer. The acquisition expanded NSIG's manufacturing and technological presence outside China and gave the group an established European operating platform. During the same year, NSIG acquired a 14.5% stake in Soitec, a French semiconductor-materials company. NSIG subsequently reduced its ownership interest in Soitec, but the investment formed part of the group's early international semiconductor-materials strategy. The company later entered China's public capital markets. On 20 April 2022, NSIG completed its initial public offering and became listed on the Shanghai Stock Exchange STAR Market. The cited reference material states that the offering raised approximately $341 million and that the company's shares increased by more than 180% on their first day of trading. The listing occurred amid heightened policy and market focus on domestic semiconductor supply chains and materials. In May 2022, NSIG announced a plan to invest approximately $408.6 million in a new production plant in Finland, with Okmetic designated to take responsibility for the project. This announcement indicated that the group intended to continue expanding its international manufacturing base while using its Finnish subsidiary as an important part of its wafer operations. NSIG is described in the reference material as China's largest domestic semiconductor-wafer producer. Its development has therefore combined state-linked founding support, acquisitions of overseas wafer and materials businesses, strategic equity investment, and public-market financing.
