In integrated circuit manufacturing, photolithography or optical lithography is a general term used for techniques that use light to produce minutely patterned thin films of suitable materials over a substrate, such as a silicon wafer, to protect selected areas of it during subsequent etching, deposition, or implantation operations. Typically, ultraviolet light is used to transfer a geometric design from an optical mask to a light-sensitive chemical (photoresist) coated on the substrate. Th… A photomask 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). Several masks are used in turn, … See more For IC production in the 1960s and early 1970s, an opaque rubylith film laminated onto a transparent mylar sheet was used.

WebOptical lithography (also known as photolithography) is a technique based on transferring a pattern from a mask to a surface using a radiation source, such as visible UV light or X-rays. For this process, a photosensitive material is exposed through a photomask and the exposed areas suffer a change on its chemical properties. WebThe photolithography used in microcircuit fabrication sequences, also called lithography and microlithography, is an image formation and transfer process, which evolved from that used in the printing industry for about 200 years. The word lithography actually means “writing on or with a stone.”.
