01 | Cross section of a photolithography mask |
||
02 | Laser exposure | Heidelberg DWL200, Laser lithography system |
The laser beams on the surface of the photoresist. By doing so, it imprints the pattern of the design on the PR. |
03 | Developing of the mask | DV10 Mask and Thick positive resist developer |
A chemical treatment is used to remove the PR that was exposed by the laser in the previous step, creating the ‘holes’ on the photoresist |
04 | Etching of the chrome | Coillard Gravure |
The chrome is removed at the sites where the resist layer is missing, using an acid bath. |
