Nickel deposition
Nickel can be deposited by e-beam evaporation, sputtering or electroplating. In the chart below you can compare the different deposition equipment.
E-beam evaporation (Temescal) | E-beam evaporation (Wordentec) | Sputter deposition (Lesker) | Sputter deposition (Sputter-system Metal-Oxide (PC1) and Sputter-system Metal-Nitride (PC3)) | Electroplating (Electroplating-Ni) | |

General description | E-beam deposition of Nickel | E-beam deposition of Nickel | Sputter deposition of Nickel | Sputter deposition of Nickel | Electroplating of Nickel |
Pre-clean | Ar ion bombardment | RF Ar clean | RF Ar clean | None | |
Layer thickness | 10 Å to 1 µm * | 10 Å to 1 µm * | 10 Å to 5000 Å ** | 10 Å to 5000 Å ** | ~ 20 µm to ~ 1000 µm |
Deposition rate | 2-10 Å/s | 10-15 Å/s | Depends on process parameters, about 1 Å/s | Depends on process parameters, at least ~ 4 Å/s, see conditions here | ~ 10-250 Å/s |

* To deposit a cumulative thickness above 600 nm permission is required from metal@nanolab.dtu.dk to ensure enough material is present in the machine
** To deposit a cumulative thickness above 200 nm permission is required from metal@nanolab.dtu.dk to ensure enough material is present in the machine
