How is a Photomask Used?

Photomask Usage

300x300-PRODUCT02The photomask image consists of a binary pattern accurately replicating the original design.  While photomasks have a variety of applications, the majority are used to support the customers  microlithography process as an intermediate step between design and manufacture of IC, photonics, and MEMS devices.

This binary pattern modulates the intensity of light in the lithography tool being used to ‘print’ the design on to the silicon wafer or other substrate being used.
