Zhangjiakou to build the country's largest germanium silicon alloy single crystal wafer base

A total investment of 120 million yuan of "silicon germanium alloy single crystal wafer and project recently in Zhangjiakou Xuanhua City Development Zone construction. After the completion of the project, Xuanhua will become the country's largest and Asia's largest single crystal silicon germanium and wafer production base.

Xuanhua District of Zhangjiakou City SiGe alloy single crystal wafer and the project is the Hebei provincial development and Reform Commission approved the project of high technology industrialization demonstration project focus. The total investment of the project is 120 million yuan. Currently, the project has been included in the city's 11th Five-Year plan. Relying on Xuanhua Xuanhua 701 factory has high-tech product core technology and human resources, information industry cluster advantages, domestic and foreign markets, and actively create a national and even Asia's largest silicon germanium alloy single crystal and wafer production base.

In order to facilitate the further development of enterprises, Xuanhua district will build engineering silicon germanium alloy single crystal wafer and project as a key project of the next year. The first phase of the project investment of 61 million yuan, after the completion of the project can produce SiGe alloy and single crystal wafer, semiconductor grade silicon single crystal wafer, and FZ Silicon wafer, and solar grade silicon single crystal wafer, and germanium single crystal wafer, and silicon germanium antimony alloy single crystal, lithium niobate single crystal and other seven kinds of products. The product has a broad market in the developed countries and regions as well as the domestic market. After the completion of the first phase of the project, the annual sales income of 57 million 436 thousand yuan, profits and taxes of $28 million 624 thousand. After the completion of the project, to achieve the annual production capacity of silicon, germanium semiconductor material more than 1 million 70 thousand kg, to achieve sales revenue of more than 19.52 yuan, profits and taxes to achieve more than 560 million yuan, earning $780 million, accounting for the domestic market share of 60%.

Xuanhua 701 factory was founded in 1959, is the national military products fixed-point production of semiconductor materials factory. Since 1960 put into production, R & D and production of high purity germanium dioxide and two metal germanium, germanium crystal, germanium, polycrystalline silicon, monocrystalline silicon and other semiconductor materials, has made an important contribution to the construction of national defense and electronic industry development in China, is the key enterprises in Hebei province and the national production of rare metal semiconductor materials. In recent years, due to fierce market competition, the enterprise is also facing difficulties. After efforts to improve the ability of independent innovation, the plant and the Hebei University of Technology, the germanium silicon alloy single crystal and wafer, a new type of information materials research and development, and success. The results in the domestic leading level, filling the domestic blank. At present, the 701 plants have mastered the core technology of single crystal melting, single crystal pulling and so on.
