prelayer
A prelayer is a thin film or coating applied to a substrate before the main functional layer is deposited. The purpose of a prelayer is to improve the adhesion, compatibility, or performance of subsequent layers. It can act as a buffer, a primer, or a diffusion barrier.
In semiconductor manufacturing, prelayers are commonly used to promote the adhesion of photoresist materials to silicon
The composition of a prelayer depends heavily on the specific application. It can range from simple organic
The deposition techniques for prelayers are diverse and include methods such as sputtering, chemical vapor deposition,
