What is a chrome mask?
The core of photo masks meeting for high-precision pattern.By selecting quartz glass as substrate, it is possible to stabilize the dimensions under the temperature changes during exposure.Corresponds to the minimum pattern width of 2μm.
MEMS、FPD（LCD/OLED）、WLP、Thin fime chip products etc.
- No fringe, suitable for ultra high-resolution image-formation.
- By selecting quartz glass as substrate, it is possible to stabilize the dimensions under the temperature changes during exposure.
- Excellent transcription performance with its thin light-shielding film.
- Corresponds to the minimum pattern width of 2μm.
