Recently, Suzhou Oriental Semiconductor Co., Ltd. (hereinafter referred to as “Oriental Semi”) held a grand groundbreaking ceremony for its R&D and Production Headquarters Base Project in Suzhou Industrial Park. Members of the Standing Committee of the Suzhou Municipal Party Committee, leading officials of Suzhou Industrial Park, and the senior management team of Oriental Semi attended the ceremony.

This marks a milestone step for the company in capacity expansion, technological upgrading and long-term development strategy. The groundbreaking of the new base is not only a new monument in the company’s development journey, but also a key strategic layout for it to further delve into the high-performance power semiconductor industry and strengthen its core competitiveness.

Strategy Anchored, Core Momentum Empowered

As a leading enterprise in China’s high-performance power device sector, the construction of the new headquarters base represents a pivotal strategic layout of Oriental Semi based on its long-term development roadmap. The project has advanced efficiently from decision-making to implementation. Supported by the “land acquisition followed by immediate commencement” policy of Suzhou Industrial Park, the project has progressed smoothly and achieved compliant and efficient launch.
