What is a glass mask?

glass mask

Emulsion glass mask realizing highest resolution and dimensional stability.


FPD(LCD/OLED), Electronic Parts, Package etc.


  • High dimensional stabilty (Glass substrate)
  • High accuracy on exposure (Thin emulsion layer)
  • Support detailed order from data editing.
  • High resolution of emulsion, corresponds to 20μm line fine pattern.

Pattern less than 20 μm is acceptable depending on the conditions.
