What PSK does
PSK Inc. is a South Korean semiconductor capital equipment manufacturer focused on wafer cleaning and stripping process tools. The company builds and sells four primary product platforms: the SUPRA series for dry strip processing (in which PSK claims the No. 1 global market share), the INTEGER series for dry cleaning of high-aspect-ratio contacts, the OMNIS series for new hard mask (NHM) stripping with high selectivity, and the PRECIA series for wafer edge cleaning. All four platforms target precision, throughput, and lowest cost of ownership at advanced semiconductor nodes, with PSK marketing the SUPRA and PRECIA lines on smallest-footprint, highest-throughput, and lowest-CoO economics versus conventional tools.
PSK generates revenue through direct enterprise sales of capital equipment to global semiconductor manufacturers. Its customer base is described generically as global semiconductor fabs, with sales coverage across 25 regions and dedicated networks in Korea, North America, China, broader Asia, and Japan. Pricing is quote-based under multi-year enterprise contracts, and the company maintains investor relations, ESG reporting, and active participation in industry events such as SEMICON Taiwan. The company is publicly listed on the Korea Exchange (KOSDAQ) under ticker 036030, reports under a group structure with wholly-owned subsidiaries PSK Holdings and SEMIgear, and discloses a CY2025 revenue of 457,213 KRW Million with a stated strategic goal of reaching USD 1 billion in revenue by 2030. Group headcount stands at 726 employees across headquarters in Seongnam-si, an additional office in Hwaseong-si, and an R&D center in Yongin established in 2022.
