In computing, lithography is the process of imprinting patterns onto semiconductors to use in circuits.
Photolithography is used to transfer a pattern from a photomask to the surface of a substrate.
The first stage is the imposition of a structure on the beam of light, which is passed through a mask and projected onto the silicon wafer.
The ‘resist’, which is a coating on the wafer, undergoes chemical changes when exposed to light. The solubility of the material is modified and formed into a stencil through the application of a solvent.
What’s the next stage?
Standard Definition Exists?
A method analogous to lithography, used in making printed circuits.
