What is a photomask?
A glass plate coated with an opaque surface, which can be etched with highly detailed patterns.
The most common type of photomasks are quartz glass plates with an opaque chrome layer.
Less common types with opaque layers are iron oxide or photographic emulsion.

A photomask is an opaque plate with holes or transparencies that allow light to shine through in a defined pattern. They are commonly used in photolithography.
