Changsha Shaoguang Core Material Technology Co., Ltd. (hereinafter referred to as "Shao Guang Xincailiao" or "the Company") originated from a major national science and technology project approved in 1980, dedicated to manufacturing photomask substrates for domestic integrated circuit chip production. The Company is the pioneer in producing photomask substrates in China.
The company was established as an independent legal entity in August 2003 and registered in Changsha. It successfully underwent restructuring in March 2011. After the restructuring, the company gradually developed from scratch into a private high-tech enterprise specializing in the research, development, and production of photomask substrates and optical components. In August 2022, the company began introducing external institutional investors and utilized multiple rounds of market-oriented venture capital funds to advance the layout of its high-end quartz photomask substrate business. Meanwhile, under the guidance of key domestic clients, its ultra-precision optical business continuously achieved technological breakthroughs, entering a phase of rapid growth.
In May 2025, the company established its wholly-owned subsidiary in Shanghai—Shao Guang Xin Cai (Shanghai) Technology Co., Ltd.—aimed at expanding the ultra-precision optical business from optical components to modular and integrated products, striving to provide core clients with one-stop optical solutions. In June 2025, the company invested in and acquired a stake in Shanghai Gaoguang Micro Semiconductor Technology Co., Ltd., entering the photomask protective film business and offering another upstream core key material for photomask customers.
The company currently employs over 400 staff, with a technical team exceeding 100 members, including several overseas experts specializing in semiconductor-grade material R&D and production for more than 15 years. It has also established industry-university-research collaboration partnerships with multiple universities and research institutes. After years of development, the company has successively established R&D and production bases in Changsha, Liuyang, and Shanghai, forming a business framework system of "three core businesses + four production bases." Additionally, the company has obtained nearly 100 patent authorizations, earning it the title of National-level Specialized and Sophisticated "Little Giant" Enterprise, as well as recognition as a National-level High-tech Enterprise.After over forty years of vicissitudes, the company has deeply realized that enterprise development is closely intertwined with the nation's destiny. Shaoguang Semiconductor Materials will continue to focus on its core business, delving into the critical materials and components for chip manufacturing. Driven by technological innovation, it will optimize its product structure, capture the high-end market, and establish a platform of materials and components spanning the semiconductor and display industries, becoming a key supplier in this field domestically.
