Shenzhou Semiconductor Completes IPO Guidance, Supplies International Semiconductor Giants Intel and SMIC Appear on Shareholder List

《Science and Technology Innovation Board Daily》April 2 News (Reporter Chen Junqing) The CSRC disclosure platform shows that Jiangsu Shenzhou Semiconductor Technology Co., Ltd. (hereinafter referred to as “Shenzhou Semiconductor”) has updated its guidance status to guidance acceptance.

The guidance work completion report shows that Shenzhou Semiconductor plans to apply for an IPO and list on the STAR Market. It is reported that the company submitted its IPO guidance filing to the Jiangsu Securities Regulatory Bureau on December 17, 2025, and the guidance period lasted about 3 and a half months.

Public information shows that Shenzhou Semiconductor is a provider of semiconductor production-line power system services. It is located in the Weiyang Economic Development Zone, Yangzhou City, Jiangsu Province. In the company’s early days, it started with RF power supply maintenance for DVD equipment, and later moved into the semiconductor Fab customer segment; afterward, it overcame key components through independent R&D and then transitioned into a provider of plasma system solutions, undertaking national Torch Program projects. Today, its business spans across Asia, with offices in multiple cities at home and abroad.

Shenzhou Semiconductor’s main business is the R&D and production of core components for semiconductor equipment, focusing on the high-precision and highly specialized sub-segment of plasma generation systems. Its products include remote plasma source generation systems (RPS), plasma radio-frequency power supplies (RF), and other key components.

According to its official website, Shenzhou Semiconductor has more than 400 employees, more than 260 engineers, and 50 simulation testing lines. It has built maintenance and testing platforms such as DC, RF, microwave, network matchers, and remote plasma generators. It is the undertaking unit for the Ministry of Science and Technology’s national Torch Program project “Construction of the Plasma Power Supply R&D and Application Platform.”

As of now, Shenzhou Semiconductor’s products cover 7-nanometer advanced processes, and have achieved breakthroughs in deep etching at above 300 layers. The company’s customers include leading domestic equipment makers such as Weihaiwei Company, Tuojing Technology, and North Huachuang, as well as wafer fabs such as Semiconductor Manufacturing International Corporation and Yangtze Memory. It has also entered the supply chains of international giants such as Intel, Samsung, and Applied Materials(AMAT).

For its 2026 development plan, Shenzhou Semiconductor’s founder and chairman Zhu Peiwen revealed in a media interview that, on the one hand, it will further increase investment in R&D of independently developed advanced-process products. On the other hand, it will comprehensively upgrade the technical support service network. Technical support services and independently developed business are mutually reinforcing and complementary collaborative businesses. The “explosion” of independently developed products in the future will also bring about more demand for technical support services.

The guidance filing shows that Zhu Peiwen is the controlling shareholder and the actual controller of Shenzhou Semiconductor, directly holding 23.29%, and controlling 49.94% of the voting rights through limited partnership entities and acting-in-concert relationships. Zhu Peiwen, in total, controls 71.21% of the voting rights.

As introduced, Zhu Peiwen founded Shenzhou Technology in Yangzhou, Jiangsu in 2001. He initially engaged in RF power supply maintenance for optical disc DVD production equipment, and later expanded the business to customers such as panel factories and semiconductor Fab factories. In 2008, Zhu Peiwen led the team to research RF power supplies and remote plasma generators. In 2016, Jiangsu Shenzhou Semiconductor Technology Co., Ltd. was officially established, focusing on semiconductor production line power systems.

Besides Zhu Peiwen, according to the business information, the shareholder list of Shenzhou Semiconductor also includes Intel Asia-Pacific R&D Co., Ltd., National Integrated Circuit Industry Investment Fund II Co., Ltd., Shanghai Pucheng Private Equity Investment Fund Partnership (Limited Partnership), Yixing Gaoyi Venture Capital Partnership II (Limited Partnership), Shanghai Yanquan Technology Co., Ltd., and Micro Semiconductor (Shanghai) Co., Ltd. The shareholding ratios are 9.47%, 5.26%, 2.37%, 2.08%, 1.96%, and 1.5%, respectively.

Shenzhou Semiconductor has gone through 4 rounds of financing. Investors include industry partners such as Intel Asia-Pacific R&D Co., Ltd. and Micro Semiconductor (Shanghai) Co., Ltd., well-known state-owned capital such as National Integrated Circuit Industry Investment Fund II Co., Ltd., Hubei Integrated Circuit Industry Investment Fund, Shanghai Pucheng Private Equity Investment Fund Partnership (Limited Partnership), and industry capital such as Zhiwei Capital, Zhiwei Panfeng Fund, and international venture capital institutions including Guofang.
