Photolithography is a patterning process in chip manufacturing. The process involves transferring a pattern from a photomask to a substrate. This is primarily done using steppers and scanners, which are equipped with optical light sources. Other forms of lithography include direct-write e-beam and nanoimprint.

In the case of semiconductor lithography (also called photolithography) our stones are silicon wafers and our patterns are written with a light sensitive polymer called a photoresist.

Photolithography is the most common method for the semiconductor fabrication of integrated circuits ("ICs" or "chips"), such as solid-state memories and microprocessors. It can create extremely small patterns, down to a few nanometers in size. It provides precise control of the shape and size of the objects it creates.

2021年12月13日 · What is Semiconductor Lithography? Semiconductor lithography or photolithography is a fabrication process that transitions from highly complex circuit patterns drawn on a photomask made of a large glass plate to a reduced version of ultra-high-performance lenses and exposed onto a silicon substrate which is usually known as a wafer.

Lithography is the process of transferring patterns of geometric shapes in a mask to a thin layer of radiation-sensitive material (called resist) covering the surface of a semiconductor wafer. Figure 5.1 illustrates schematically the lithographic process employed in IC fabrication.

For over 30 years, semiconductor lithography has yielded a broad spectrum of photoresist polymers that implement novel chemical designs and concepts for patterning in two dimensions, which may inspire new approaches for AM in three dimensions [213–215].

The fabrication of an integrated circuit (IC) requires a variety of physical and chemical processes performed on a semiconductor (e.g., silicon) substrate. In general, the various processes used to make an IC fall into three categories: film deposition, patterning, and semiconductor doping.
