[Semiconductor_Foundry] PSMC: Falling Behind the Major Taiwanese Foundries, but Demonstrating Strong Competence in Legacy Processes

[Posting: 2025.04.26] Taiwan’s PSMC (Powerchip Semiconductor Manufacturing Corporation) , which excels in legacy processes, operates both 200mm and 300mm FABs . The company is expanding specialty processes such as Power IC BCD (Bipolar-CMOS-DMOS) , embedded NVM (Non-Volatile Memory) for MCU application and CIS into the automotive sector . Its major clients include prominent IDMs and fabless companies like Infineon and ON Semiconductor , which together account for approximately 30% of its revenue , indicating PSMC's strong process competitiveness. PSMC possesses mass production capabilities for planar transistors (up to the 28nm technology node ) within its legacy processes, suggesting stable future revenue growth in the automotive sector. Currently, there is a strong trend among fabless companies to seek NCNT (Non-China, Non-Taiwan) foundry options to mitigate geopolitical risks. This factor is expected to significantly influence PSMC’s future sales. I will cont...
