WebbThe word lithography (Greek for the words stone [ lithos] and to write [ gráphein ]) refers to the process invented in 1796 by Aloys Senefelder, who inked Bavarian limestone and … WebbPhotolithography, also called optical lithography or UV lithography, is a process used in microfabrication to pattern parts on a thin film or the bulk of a substrate (also called a wafer). It uses light to transfer a geometric pattern from a photomask (also called an optical mask) to a photosensitive (that is, light-sensitive) chemical photoresist on the …

WebbBasic Principles of Photolithography. Figure 1 illustrates a typical photolithography process used to define shallow trench isolation features. Such a process consists of the following steps: Substrate cleaning and preparation. Form layers of thermal oxide and deposit a layer of silicon nitride on the clean substrate. WebbPhotolithography has been a practical technique for microstructure fabrication. The ability of parallel process is the key issue for the large-scale production. Because the minimum …
WebbPhotolithography is a process used in microfabrication to transfer geometric patterns to a film or substrate. Geometric shapes and patterns on a semiconductor make up the complex structures that allow the dopants, electrical properties and wires to complete a circuit and fulfill a technological purpose.
