How is a Photomask Made? We outline the process here
How is a Photomask Made? We outline the process here

A photomask is made by exposing, or writing, the designer’s pattern onto a resist coated chrome ,mask, blank. The latent image in the resist is then developed to form the required pattern. This resist image acts as a ,mask, during the etching process. The pattern is transferred into the chrome film when the resist layer is removed.
