Changsha Shao Guang Core Materials Technology Co., Ltd. was established in August 2003. It was formerly a project funded by the state for the production of optical mask substrates. It is a national-level key specialized and innovative "small giant" enterprise and an industry manufacturing single-item champion in Hunan Province. The company focuses on the research, development, production and sales of optical mask substrates and precision optical components. It is the only domestic enterprise that masters the core technologies of the entire process of quartz optical mask substrates and has achieved large-scale production. It has undertaken the national major project on advanced process mask substrates. Its products cover the semiconductor and general display fields. At the same time, it has also entered the business of ultra-precision optical components, and its technical strength and shipment scale are both at the leading level in China. 

Currently, the photomask substrate (Blank mask) is the core foundational material in the chip manufacturing process. It has high technical barriers and a prominent strategic position in the supply chain. The high-end market has long been monopolized by foreign manufacturers, and there is an urgent need for domestic substitution. Shaoguang Ceramics has achieved full-process control over the grinding and polishing of quartz substrates, magnetron sputtering coating, and photomask coating. It has formed a complete product range covering I/G-line, KrF, and ArF nodes. It has been the first to achieve mass supply to leading mask factories and wafer factories in China. Relying on advanced processing technology and precise process flow, the company's photomask substrate products meet international standards in terms of performance and reliability, and its technical level is leading domestically. Its market share has steadily increased. At the same time, the company's ultra-precision micro-nano optical component business, with its unique micro-nano structure design, has deeply integrated with domestic leading semiconductor equipment manufacturers and is widely used in high-end fields such as microelectronics, optical communication, and biochips. It forms a dual-drive with the photomask substrate business, and has broad growth potential. 

Shangqie Capital's investment team stated that mask substrates are one of the key links in achieving China's independent control over the semiconductor industry chain, and there is a strong demand for domestic substitution. Shaoguang Materials, as a scarce domestic company with full-process independent production capabilities, has significant advantages in technological research and development, product certification, customer introduction, and capacity layout. The company, leveraging its profound technical accumulation and innovation capabilities, is gradually breaking the monopoly of foreign enterprises and promoting the domesticization process of semiconductor materials, contributing to the development of Chinese chips.
