Sputtering
Sputtering is a technique for depositing a variety of materials onto a substrate. This is achieved by bombarding a material with argon causing the atoms on the surface of the material to vaporize and coating everything inside the vacuum chamber. This technique can deposit materials at a rate of up to 0.1 [nm/s].

|---|---|
| Base Pressure | The base pressure is an important process parameter. The trace gases are characterized for the AJA ATC-2200. |
| Uniformity | The deposition uniformity is an important process parameter to control to ensure homogenous material properties across an entire wafer. The uniformity depends on the gun angle, gun position and throw distance. The uniformity is characterized for the AJA ATC-2200. |
| System Geometry | The sample to target distance is an important, yet often overlooked parameter when specifying a sputtering process. It affects the sputtering rate and sometimes the material properties. The standard process target to sample distance is approximately 17 cm. |
