The photolithography process in chip manufacturing includes the following steps:

1. Wafer Cleaning: This is the initial step where the silicon wafer is cleaned to remove any dust or impurities. This is crucial to ensure the smooth application of the photoresist material in the next step.

2. Application of Photoresist: In this step, a light-sensitive material called photoresist is applied to the wafer. This material will form the pattern of the circuit on the wafer.

3. Etching: After the photoresist is exposed to light and develops the circuit pattern, the exposed areas are removed by a process called etching. This process uses chemicals to remove the unwanted material, leaving behind the desired circuit pattern.

The steps Doping and Ion Implantation are not part of the photolithography process. They are separate processes used in chip manufacturing.

Doping is a process where impurities are intentionally added to the semiconductor to change its properties.

Ion Implantation is a process used to implant ions into the semiconductor material. This is done to change the physical, chemical, or electrical properties of the semiconductor.
