Photronics is a company that manufactures and sells photomasks. It offers photomasks, which are high precision photographic quartz plates containing microscopic images of electronic circuits for the use in the manufacture of semiconductors and flat panel displays (FPDs), as well as that are used as masters to transfer circuit patterns onto semiconductor wafers and flat panel display substrates during the fabrication of integrated circuits, FPDs, and other types of electrical and optical components. The company sells its products to semiconductor or FPD designers, manufacturers, and foundries.
