Physical display of glass photomask lithography products

crafting process:

(1) Draw a mask reticle layout file (GDS format) that can be recognized by the generation device

2) Use a maskless lithography machine to read the layout file, perform non-contact exposure (exposure wavelength 405nm) on the blank reticle with glue, and illuminate the required pattern area on the  reticle to make the photoresist in this area. (usually positive glue) undergoes a photochemical reaction

3) After developing and fixing, the photoresist in the exposed area dissolves and falls off, exposing the underlying chromium layer

4) Use chromium etching solution for wet etching, etch the exposed chromium layer to form a light-transmitting area, and the chromium layer protected by the photoresist will not be etched, forming an opaque area. In this way, plane pattern structures with different light transmittances are formed on the  reticle.

5) If necessary, use wet or dry methods to remove the photoresist layer on the  reticle, and clean the reticle.
