Photomask plasma etching: a review
WebMar 23, 2024 · Mask making is a fabrication process where a computer-aided design (CAD) is transferred to a thin (80-100 nm) layer of metal in a glass or fused silica substrate, known as mask or photomask. The metal works as an absorption layer for light at different wavelengths. The standard photomasks use Chromium as absorption material for i-, g- … Webcritical dimension (CD) change of as much as 0.02 µm. For photomasks, it was determined that a hot plate bake (HPB) of 10 minutes was required at 105 o C to activate the acid …
