- WOT Co., Ltd. is a South Korea-based technology company specializing in the design, engineering, and manufacturing of ultra-precision environmental control systems for semiconductor and display manufacturing processes. Founded in 2004 and headquartered in Hwaseong-si, Gyeonggi-do, South Korea, the company operates within the semiconductor equipment sector, delivering high-reliability hardware and solutions that regulate microscopic environmental parameters in critical cleanroom and fabrication workflows.
The company's core product and service offerings comprise: Temperature and Humidity Control (THC) systems, which provide ultra-precise microclimate regulation within semiconductor photolithography and track equipment; Temperature Control Units (TCU), designed to maintain consistent thermal conditions across etching, advanced packaging, and display manufacturing stages; Fan Filter Units (FFU), which filter cleanroom air, regulate air currents, and eliminate airborne microparticles; Chemical Handling Modules (CHM) and chemical filtration units, providing automated chemical supply management and gas filtration; and comprehensive post-installation support services, including semiconductor equipment maintenance, system retrofitting, calibration, and replacement component provisioning.
WOT Co., Ltd. primarily serves major global memory and logic manufacturers as well as equipment integration partners, including Samsung Electronics, SK Hynix, and SEMES. While the company maintains its primary manufacturing and research facilities in South Korea, it distributes its products across key semiconductor manufacturing hubs in East Asia, including Taiwan and mainland China.
In recent operational and strategic developments, WOT Co., Ltd. has completed its public listing on the KOSDAQ market (Ticker: KRX:396470) and expanded its equipment portfolio to address high-growth artificial intelligence semiconductor segments. The company has successfully developed and qualified advanced THC equipment for High Bandwidth Memory (HBM) stacking processes and Extreme Ultraviolet (EUV) photolithography lines for major Korean chipmakers. Additionally, WOT has expanded its TCU portfolio to include HBM debonding applications and high-precision printed circuit board (PCB) processing equipment, while advancing energy-efficient environmental control technologies and actively pursuing global customer diversification across Asian semiconductor fabrication markets.
