Wanhua Electronic Materials, a company based in Yantai Huang-Bohai New Area, has received major strategic investment from Sinopec Capital, indicating State-backed support for the city's rapidly growing semiconductor industry.

The firm specializes in electronic specialty gases for semiconductors, display panels, and photovoltaic products, and excels in producing high-purity disilane. In 2025, it achieved large-scale mass production through its proprietary magnesium silicide process, increasing the disilane synthesis yield to above 30 percent. Its products reach a purity of 99.99 percent, and the company operates the world's largest disilane production unit, with an annual capacity of 50 metric tons.

Sinopec Capital, the investment branch of the State-owned energy giant Sinopec, focuses on new energy, advanced materials, high-end manufacturing, and artificial intelligence. It has previously invested in major industry players, including Ruihong Suzhou and Wanrun.

Driven by AI's rise globally, demand for advanced chips, such as 3D NAND and FinFET, has surged, making disilane an essential semiconductor raw material. Wanhua's domestic advancement significantly furthers China's drive for semiconductor material localization.

Under its hydrogen energy fund, Sinopec Capital will work with Wanhua to integrate technology, capital, and industry resources, further accelerating the high-quality development of China's semiconductor sector.
