Lianwei: SMIC is the company's second largest customer for semiconductor silicon wafer business

On November 17, Lianwei said on the interactive platform that the company's main customers for semiconductor silicon wafer business include China Resources Microelectronics, SMIC, Shenzhen Shenai Semiconductor Co., Ltd., Shanghai Advanced, Silan Microelectronics, etc. SMIC is one of the company's important customers, selling silicon epitaxial wafers and silicon polished wafers. According to preliminary statistics, it is currently the second largest customer for the company's semiconductor silicon wafer business.

It is understood that Liangwei is involved in three major business segments: semiconductor silicon materials, semiconductor power devices, and integrated circuit manufacturing. Among them, semiconductor silicon materials are one of Liangwei's core business segments. As early as the end of 2016, Liangwei invested in the construction of its second semiconductor silicon wafer production base in Quzhou, Zhejiang, in addition to Ningbo, and successively established Jinruihong Technology (Quzhou) Co., Ltd. and Jinruihong Microelectronics (Quzhou) Co., Ltd.

According to a previous report by Jiwei.com, Lianwei's 12-inch silicon wafer project has passed product verification by several customers and has achieved mass production and sales. It is continuing to expand production and is expected to reach an annual output of 1.8 million pieces after the project is completed by the end of 2021.

In addition, the "6-inch GaAs microwave RF chip project" of Lianwei has currently built an annual production capacity of 30,000 pieces, passed product verification by several customers, and achieved mass production and sales. It is currently implementing capacity expansion and is expected to expand to an annual production capacity of 70,000 pieces by the end of June 2021. The products are widely used in 5G wireless communications, face recognition, optical devices, Bluetooth headsets, WIFI, etc.
