JZSG Semiconductor Materials Technology was founded in July 2003.
The company focuses on the R & D, production and sales of single crystal silicon materials for integrated circuit etching. With high-quality products and perfect after-sales service, JZSG has established a good reputation in the field of monocrystalline silicon materials for integrated circuit etching. The international advanced semiconductor material industry chain system has established its position in the industry.
After years of technology research and development and accumulation, pursuing excellence in craftsmanship and continuously climbing the peak of the industry, JZSG has broken through and optimized a number of key technologies. The company's non-magnetic field large-diameter single crystal silicon manufacturing technology, solid-liquid coexistence interface control technology, thermal field size optimization process and other technologies are all at the international advanced level.
JZSG can mass-produce ultra-large diameter semiconductor grade silicon single crystal material with a maximum yield of Φ475㎜ (19 inches), with resistivity covering 70-80Ω · cm, 1-4Ω · cm and <0.02Ω · cm etc. specifications, which can meet Customers' demand for all kinds of high school, low resistance products.
In particular, JZSG's semiconductor etching machine mass-produces 19-inch silicon single crystal technology with a 28-inch thermal field without magnetic field, reaching the international advanced level and breaking through the international monopoly.
In addition to providing silicon single crystal rods, JZSG also has the ability to process subsequent crystal rods, and can provide products such as silicon cylinders, silicon disks, and silicon ring wafers. Almost all of the company's products are exported to mainstream customers in Japan, South Korea and the United States. The global market share in the field of etching single crystal silicon materials is about 13% -15%.
The company's main customers include Mitsubishi Materials, SK Chemicals, CoorsTek, Hana, Silfex, Trinity, Wakatec, WDX, etc.
In 2019, the company will invest in 8-inch semiconductor-grade silicon single crystal polishing wafer production and construction projects and R & D center construction projects, totaling 1.102 billion yuan. Among them, after the 8-inch semiconductor-grade silicon single-crystal polished wafer production and construction project is completed, the company will have an annual capacity of 1.8 million 8-inch semiconductor-grade silicon single-crystal polished wafers and 360,000 semiconductor-grade silicon single-crystal companion wafers.
