Copper can be deposited by e-beam evaporation. In the chart below you can compare the different deposition equipment.


E-beam evaporation (Alcatel) Sputter deposition (PVD co-sputter/evaporation)
Batch size
  • Up to 1x4" wafers
  • smaller pieces
  • 4x6" wafers or
  • 4x4" wafers or
  • 4x2" wafers
Pre-clean RF Ar clean
