Description

Photo Mask is like film of photo.

As multiple photos can developed with one film, numerous circuits and patterns can be transcribed by using Photo Mask.

Photo Mask is mainly used in the process required of photolithography.

That is used for LSI, LCD, PWB, etc.

Photo Mask used in the photolithography process is master mask for making the semi-conductor chip, LCD, etc. so that it may be

ultra-precise core part and the most important raw material which is the basis of semi-conductor technology, FPD(Flat Panel

Display) and package technology.
