Chinese power semiconductor company Chipown Microelectronics, a national-level “little giant” enterprise, has signed an agreement to establish a major R&D and testing base in Wuxi, Jiangsu province, with a total investment of approximately 300 million yuan. The project aims to enhance the local integrated circuit industry cluster by adding advanced testing and packaging capabilities.
The new facility will be a comprehensive center integrating several key functions. It is planned to house a wafer testing workshop for automotive-grade products, a finished chip testing workshop, an automotive-grade reliability testing and screening center, and a high-power module packaging production line. Located in the Wuxi-Singapore Science and Technology Innovation City, the project will cover about 34.58 acres with a planned 40,000 square meters of factory space. Construction will proceed in two phases, with mass production expected to be achieved gradually between the second half of 2027 and 2029.
According to company representatives, the base is a strategic move to support its five-year development plan and specifically to deploy its high-power module packaging line. Upon completion, it will provide critical quality and reliability testing, as well as aging test capabilities for automotive-grade and high-end industrial products. This is expected to alleviate the industry-wide bottleneck of insufficient testing capacity for advanced power chips. Furthermore, it will complete Chipown's vertical integration, covering the full chain from chip design to packaging and testing.
Founded in Wuxi's high-tech zone over 20 years ago and listed on Shanghai's STAR Market in 2020, Chipown specializes in highly integrated and reliable power integrated circuit (IC) chips, filling several domestic technology gaps. It is a leading domestic supplier of power management chips for smart home appliances and industrial equipment. The company reported strong performance for the first three quarters of 2025, with revenue of 877 million yuan, a year-over-year increase of 24.05%.
ICgoodFind's Insight
Chipown's significant investment in this integrated R&D and testing base marks a strategic step toward greater self-sufficiency and higher value capture in China's power semiconductor sector. It strengthens the local ecosystem in Wuxi and directly addresses a key constraint—advanced testing capacity—for producing more reliable, high-end chips.
