ULCOAT is located in Chichibu-city, Saitama prefecture, the perfect environment blessing with full of pure water and air that require to produce world's highest level of semiconductor products. The core is the coating technology = sputtering techonology that the company is named after. Sputtering in the electronics field has its stage in the world of micron = μm (micrometer, 1/1,000mm) or even nanometer = nm (1/1,000,000mm). Chrome sputtering for photomask blanks requires 5 nm uniformity within a plate. ULCOAT meets such severe specification with cutting-edge sputtering systems and inspection tools. We are leading the fields of photomask blanks and FPD in the world as well as responding to customers' requests and expectation.
