Nickel deposition
Nickel can be deposited by e-beam evaporation or electroplating. In the chart below you can compare the different deposition equipment.
E-beam evaporation (Temescal) | E-beam evaporation (Wordentec) | E-beam evaporation (Physimeca) | Sputter deposition (Lesker) | Sputter deposition (Cluster-based sputter system) | Electroplating (Electroplating-Ni) | |
