Mask Blanks

Mask Blanks/Photomasks for Semiconductor Manufacturing

Mask blanks and photomasks are essential in the production of semiconductor chips. They are the master plates used to transfer the minute, highly complex circuit patterns for semiconductors onto the wafers that become IC chips.

A photomask is a glass plate onto which a circuit pattern is drawn.

A mask blank is a substrate for a photomask. HOYA has several strengths in this field, including: (1) the superb technologies it uses to precisely polish glass substrates and then lay down homogeneous metallic films on those substrates; (2) the ability to develop new products that exactly meet client needs; and (3) excellent production capabilities, which allow the company to offer a stable supply of finished mask blanks and photomasks to the market.
