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.”. WebIn the case of semiconductor lithography, our stones are silicon wafers and our patterns are written with a light-sensitive polymer called photoresist. To build the complex structures that make up a transistor and the many wires that connect the millions of transistors of a circuit, lithography and pattern transfer steps are repeated at least 10 times, but more …
