About Us

QS Diamond

Qiansheng Superhard Materials (Dongguan) Co., Ltd. is a diamond materials technology company built around MPCVD (microwave plasma chemical vapor deposition). Our business covers in-house development of core equipment, scalable diamond materials production, and application solutions development. The business focuses on thermal management for advanced semiconductors, high-power electronic devices, and aerospace. The products cover both industrial-grade and gem-grade diamond. Diamond offers ultra-high thermal conductivity, an ultra-wide bandgap, extreme hardness, and outstanding chemical stability. It is regarded as one of the key materials to overcome the extreme heat-removal faced by next-generation high-power semiconductor and electric devices and has the irreplaceable value in advanced manufacturing area.

Around this materials value, QS Diamond builds integrated capability across equipment–process–materials–applications, continuously promotes the process of engineering and industrialization of diamond materials in critical area.
