What is Etching? Etching is the pattern transfer step in microfabrication Simply put, it s about "printing " the pattern from the photoresist onto the underlying material layer

Photolithography, simply put, is the process of "drawing circuits " on a wafer It s like developing a photograph—the photomask acts as the negative, and the photoresist on the wafer surface acts as the photo paper By precisely controlling light
