fotolitoplate

Fotolitoplate is a term sometimes used to refer to a photomask or reticle used in photolithography. Photolithography is a process used in semiconductor manufacturing and microfabrication to pattern a thin film or the bulk of a substrate. It involves the use of light to transfer a geometric pattern from a photomask to a light-sensitive chemical called a photoresist, on the surface of a substrate. The photomask itself is a plate, often made of glass or quartz, containing the desired pattern. This pattern is typically opaque in some areas and transparent in others, allowing light to selectively expose the photoresist. When the term fotolitoplate is used, it is generally referring to this critical component of the lithographic process. The accuracy and defect-free nature of the fotolitoplate are paramount for the successful creation of integrated circuits and other microelectronic devices. Specialized equipment is used to create and inspect fotolitoplates to ensure the fidelity of the patterns they hold.
