Photomasks

A photomask, also known simply as a mask or reticle, is a key component in the photolithography process used in semiconductor manufacturing and other areas of microfabrication. It is a high-precision plate or glass substrate that carries a pattern of opaque and transparent regions. Photomasks are crucial for transferring intricate patterns onto semiconductor wafers during the photolithography process.
