Jul 31, 2018 (China Knowledge) - Beijing Duet Microelectronics will invest RMB 1 billion to build China’s first advanced process technology production line of GaAs MMIC chip with large-scale mass production capacity in Beijing E-Town, and conduct. Foundry services are expected to be put into production in early 2019. GaAs is the acronym of gallium arsenide which is compound of the elements gallium and arsenic. It is a III-V direct bandgap semiconductor with a Zinc blende crystal structure, according to Wikipedia.

After the project is commenced, the 6-inch GaAs MMIC chip foundry will have a designed capacity of 20,000 pieces per month, according to a director of Beijing Duet Microelectronics.

Since the mid-1990s, GaAs MMIC has become an indispensable IC component in the wireless communications industry, replacing the low-performance silicon-based integrated circuits in the RF and microwave fields.

Since the process of manufacturing gallium arsenide devices is much more difficult than silicon-based devices, there is still no Chinese that is able to produce gallium arsenide MMIC chips. The gallium arsenide MMIC chips required by mobile phone manufacturers all rely on imported products.

The ultimate goal of the project is to become the world's leading supplier of microwave integrated circuits (MMICs), to meet the urgent demand for gallium arsenide MMIC chips in domestic market, and to reverse the unfavorable situation that domestic gallium arsenide MMIC chips are 100% imported products.

Beijing Duet Microelectronics Technology Co., Ltd. is a technology startup company that develops new solutions for the challenges of the 5G and IoT millimeter wave market, providing high performance RF components.

Currently nearly 100 upstream and downstream player along value chain of IC industry are located in Beijing E-Town. According to estimates, these companies on aggregate can contribute RMB 50 billion industrial output with RMB 16 billion profit and RMB 1.6 billion taxes to Beijing E-Town.
