CC2

The Varian CC2 is a deposition system used in semiconductor manufacturing for thin-film deposition. The Varian CC2 belongs to the class of physical vapor deposition equipment that creates thin films by ejecting material from a target. Such systems are typically employed in cleanroom environments for depositing conductive, insulating, or semiconducting layers.

The process is controlled by adjusting the gas pressure, applied power, and substrate temperature. Many systems can deposit multiple materials sequentially or simultaneously using multiple targets. Substrate rotation is often used to improve film uniformity across the wafer.

Sputter deposition systems are used in the metallization and dielectric deposition steps of semiconductor fabrication. The process typically follows surface cleaning or patterning steps and precedes subsequent lithography or etching steps. The deposited films serve as conductive interconnects, contact layers, diffusion barriers, or optical coatings.

In a typical process flow, a sputter deposition step may be used to deposit a metal seed layer for electroplating or to form the gate electrode material. The system can also deposit compound films when reactive gases are introduced into the plasma chamber.

The system is suitable for research and low-volume production environments where flexibility in material choice and process conditions is important. Films can be made with controlled composition and thickness for specialized device structures.
