Jingge Semi (晶格半导体) is an enterprise deeply engaged in the field of semiconductor-grade silicon materials, focusing on the research, development, production and application of silicon materials.

The company’s team has nearly two decades of profound experience in research, development, production and management in the field of silicon materials, and has successfully mastered the world’s leading and unique full-melting ingot technology and purification Czochralski single crystal technology.

In addition, the company has the complete processing capabilities for silicon materials, covering all aspects such as cutting, drilling, grinding, polishing and cleaning, and is committed to providing customers with customized semiconductor-grade silicon material products and solutions.

At present, Jingge Semi is capable of mass-producing ultra-large diameter semiconductor-grade single crystal silicon materials with a maximum diameter of Φ470㎜ (19 inches) at a high yield rate. The resistivity covers specifications such as 70-80Ω·cm, 1-4Ω·cm and <0.02Ω·cm, which can meet customers’ needs for various high, medium and low-resistance products. In addition to providing single crystal silicon rods, Jingge Semi also has certain subsequent processing capabilities for silicon rods, and can provide products such as silicon cylinders, silicon wafers and silicon ring wafers. Almost all of the company’s products are exported to mainstream customers in countries such as Japan, South Korea and the United States.
