About Kempur / 科华微电子

Beijing Kehua Microelectronics Materials (Kempur) operates as a critical supplier of advanced materials to the semiconductor industry. Established in 2004 as a Sino-US joint venture, the company has positioned itself as a key domestic producer of photoresists, materials essential for the photolithography process in chip manufacturing. Kempur integrates research and development, production, and sales of its specialized products.

The company's business model is centered on B2B sales of high-purity chemical materials to manufacturers of integrated circuits (ICs), light-emitting diodes (LEDs), micro-electromechanical systems (MEMS), and other discrete semiconductor devices. Revenue is generated through the direct sale of its photoresist products and supporting reagents. Kempur serves some of the leading names in China's semiconductor sector, including SMIC, Shanghai Huali Microelectronics, and Yangtze River Storage, indicating its role as a stable partner in the regional supply chain.

Kempur's product portfolio covers a range of photoresists required for different lithography processes, including KrF (248nm), I-line, G-line, and UV broad spectrum types. These materials are used to transfer circuit patterns onto semiconductor wafers. The company has established significant production capabilities, including a 100-ton 248nm photoresist production line and larger capacity lines for G/I line positive photoresists and other supporting chemicals. A notable asset is its ownership of an ASML exposure machine, a sophisticated piece of lithography equipment used for testing and development, which distinguishes it among domestic photoresist companies.

The company's foundation and growth have been supported by national initiatives aimed at reducing China's reliance on imported high-grade photoresists. Kempur undertook the "248nm photoresist development and industrialization" project as part of the National Science and Technology 02 Major Project launched in 2010. This strategic focus has attracted multiple rounds of financing from investors such as Woyan Capital, Jiangsu Shengshi Investment, and Nata Optoelectronics, enabling the expansion of its R&D and production capacity.
