Thermal process equipment,
built and serviced in Korea.
Furnace, Spin Rinse Dryer and Software — three pillars of thermal processing for semiconductor and MEMS fabs.

01Diffusion Furnace & LP-CVDVertical and horizontal furnaces for 100 to 300 mm wafers — from atmospheric oxidation and annealing to LP-CVD nitride, poly-Si and TEOS, plus R&D furnaces for labs.View products

02Spin Rinse Dryer150 to 300 mm spin rinse dryers in single or dual stack, with carriers and rotors built in-house.View products

03SoftwareSTOS replaces legacy furnace controllers on Tempress, BTU, Kokusai and TEL systems, and FTOS drives vision lens sorting.View products
