WebA 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 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.
