Specific Process Knowledge/Thin film deposition/Deposition of Chromium
Chromium can be deposited by e-beam evaporation. It should be noted that Chromium does not melt but evaporates directly from the solid phase. Chromium can be sputter deposited aswell. In the chart below you can compare the different deposition equipment.
