About Us

SiEn (QingDao) Integrated Circuits Co., Ltd. is China s first semiconductor company based on a Commune IDM (CIDM) model, with a total investment of about 15 billion RMB. The first stage investment is around 7.8 billion RMB, from Qingdao International Economic Cooperation Zone, Qingdao West Coast New Area, Qingdao Aucuma Group Co. Ltd, and SiEn Semiconductor Corporation. The project s target is to build mass production fabs of both 8-inch and 12-inch manufacturing lines, including a photomask shop for integrated circuit manufacturing.

The project is slated to start full-line manufacturing by the end of 2019 and reach full production in 2022.

This project will establish a breakthrough development of vertical integration of semiconductor IC manufacturing in Qingdao West Coast New Development Area, and will explore the viability of replicating and promoting the CIDM model. This also will provide innovation and advanced semiconductor manufacturing capability for Shandong Province and China, for major industries such as home appliances and automobile electronics. 


Many specialized chips have long been monopolized by leading international semiconductor manufacturers. As a result, China s core products are severely deficient. This has led to over US$200 billion worth of semiconductor integrated circuits imported into China over the years.

Dr. Richard Chang and his team will install a CIDM (Commune Integrated Device Manufacturer) model suitable for the development and expansion of China s semiconductors, namely, the creation of a company with shared resources for manufacturing, chip design, research and development, packaging and testing, to provide end customers with high-quality, high-efficiency products. Using the co-sharing model, IC design companies, end application companies, and IC manufacturers jointly invest and integrate multiple parties through the establishment of a joint IDM company. This model enables IC design companies to have exclusive production capacity and technical support for chip manufacturing. At the same time, the IC manufacturers can enjoy and share the market potential, resources, and risk.

SiEn (Qingdao) has a team of world-class professional and management talents specializing in semiconductor technology R&D, management, manufacturing, operations, and investment activities.

Dr. Richard Chang, a semiconductor industry leader, has more than 30 years of experience in semiconductor manufacturing and R&D. He worked at Texas Instruments for 20 years and he successfully created and managed more than 10 wafer fabs in the United States, Japan, Singapore, Italy, Taiwan, and China. Dr. Chang is the founder of SMIC and Shanghai Shineray Semiconductor Technology Co., Ltd. The teams have extensive experience from various world-class semiconductor companies. They have published more than 200 papers in international journals and magazines, and have more than 1,000 semiconductor-related patents, many of which are with core technical and manufacturing values.

SiEn will be the first company to introduce the CIDM model in China. With world-class manufacturing capabilities, it has attracted a host of advanced semiconductor application companies from local and abroad to participate in the exciting adventure, including smart home appliances, communications, as well as automotive electronics.
