Lithography in wafer fabrication
Web12 nov. 2024 · For lithography, in particular, these steps are the coating, pre, and post bake process. Cleaning and Photoresist Coating Before you can expose a wafer to light, you must coat the wafer in a photoresist film. To do so you have to first clean the wafer, and then “pre-bake” the wafer to remove the water. WebThere are three basic pattern transfer approaches: subtractive transfer (etching), additive transfer (selective deposition), and impurity doping (ion implantation). Etching is the most …
