Term (Index) Definition
photomask  mask used in photolithography to block resist exposure to UV radiation in selected areas; consists of chrome opaque areas supported by high quality quartz plate transparent to UV radiation.
blank  part of the mask transparent to radiation featuring given wavelength; different blanks are used in photolithography and X-ray lithography.
X-ray mask  mask used in X-ray lithography; uses gold as an opaque material; gold pattern (defined using e-beam lithography) is supported by a thin membrane made out of material transparent to X-rays of given wavelength, e.g. Si3N4, SiC and others.
photoemulsion  material acting as an opaque (nontransparent to UV radiation) part of the masks used in photolithography; inferior to chrome, used for the same purpose, due to lower optical density (thicker film needed to block off UV radiation) grainy structure (not as sharp edges as in the case of chrome) and softness making it vulnerable to mechanical damage.
