Web20 jun. 2024 · History of Lithography. Lithography became a popular way for artists in France to express themselves. Prominent figures like Theodore Gericault, Francisco de Goya, and Eugene Delacroix used lithography in the 1820s. The lithograph revival was later associated with the works of Degas, Odilon Redon, and Henri Fantin-Latour. 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. T…
