350mm × 300mm Quartz Photomask Substrate For FPD Use

Applications

The fields of photolithography process, such as integrated circuit chip manufacturing, FPD (Flat Panel Display),

MEMS (Micro Electro Mechanical Systems), etc.

Working Principle

Mask is a graphic master mask commonly used in photolithography of micro-nano fabrication. The graphic structure

is formed on a transparent substrate by an opaque photomask, and then the graphic information is transferred to the

product substrate through an exposure process.
