A photomask (also simply called a mask) is an opaque plate with transparent areas that allow light to shine through in a defined pattern. Photomasks are commonly used in photolithography for the production of integrated circuits (ICs or "chips") to produce a pattern on a thin wafer of material (usually silicon ).
Simply put, a photomask is an image-transferring tool. Photomasks are comprised of a solid, transparent substrate, such as glass or fused silica, showing an opaque coating on one of the surfaces where a microscopic pattern has been etched, leaving some regions transparent and others opaque.
Dec 13, 2022 · A photomask is basically a “master template” of an IC design. A mask comes in different sizes. A common size is 6- x 6-inch. A basic and simple mask consists of a quartz or glass substrate. The photomask is coated with an opaque film. More complex masks use other materials.
Jul 29, 2023 · The meaning of PHOTOMASK is a pattern of opaque material used to shield selected areas of a surface (as of a semiconductor) in deposition or etching (as in producing an integrated circuit) : mask.
A photomask is a quartz or glass substrate, coated with an opaque film in to which is etched the design of the device being manufactured. The photomask plays a critical role in the microlithography process used by our customers for the manufacture of integrated circuits (ICs), photonic devices, and micro-electro-mechanical systems (MEMS).
Nov 18, 2022 · 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.
In electronics manufacturing, a photomask is a special stencil which is used in photolithography to create a printed circuit board or integrated circuit. When light is shone through the photomask, certain parts where the light hits the unused circuit board are strengthened, much like what toothpaste does to the hard surfaces your teeth.
