Sputtering Process Overview:

Sputtering involves bombarding the target material (arsenic telluride in this case) with high-energy particles, which eject atoms from the target. These atoms then deposit onto a substrate, forming a thin film.

This process is performed in a vacuum chamber, and various parameters such as temperature, pressure, and sputtering power can be adjusted to achieve the desired film properties.
