1. Overview of Electronic Wafer Fabrication

Electronic wafer fabrication is a complex procedure that involves several steps to transform raw silicon wafers into functional microchips. The process includes:

1. Wafer Preparation: The process begins with the selection of high-purity silicon and cutting it into thin slices.
2. Oxidation: A silicon dioxide layer is grown on the wafer's surface to protect the silicon.
3. Photolithography: This is where UV lithography plays a pivotal role. Light-sensitive photoresist is applied to defined patterns on the wafer.
4. Etching: Unprotected areas of the silicon are removed to create the desired circuit patterns.
5. Deposition: Various materials are deposited on the wafer to form multiple layers of electronic components.
