Lasertec develops optical inspection and measurement equipment. Its semiconductor products inspect photomasks, mask blanks and wafers for defects, supporting quality control in advanced chipmaking.
History and development
Lasertec began as Tokyo ITV Laboratory in 1960 and adopted its present name in 1986. Imaging and optical technology developed into precision inspection, including systems for masks used in semiconductor production. Its role is defect-detection equipment rather than semiconductor manufacture.
