Deposition of silver

Silver can be deposited by e-beam evaporation, by sputtering and by thermal evaporation. In the chart below you can compare the different methods on the different deposition equipment.

Sputter deposition of silver

Thermal deposition of silver



Comparison of Deposition Equipment for Silver

E-beam evaporation (E-beam evaporator (Temescal) and E-beam evaporator (10-pockets)) Thermal evaporation (Thermal Evaporator) Sputter deposition (Lesker) Sputter deposition (Sputter-system Metal-Oxide (PC1) and Sputter-system Metal-Nitride (PC3))
General description E-beam deposition of Ag (line-of-sight, very good thickness uniformity) Thermal deposition of Ag (line-of-sight) Sputter deposition of Ag (some step coverage) Sputter deposition of Ag including pulsed DC and HiPIMS
Pre-clean Ar ion etch (only in E-beam evaporator Temescal) none RF Ar clean RF Ar clean
Layer thickness 10Å to 1µm* 10Å to 0.5µm ** 10Å to about 2000Å 10Å to ?
Deposition rate 1 to 10Å/s 5Å/s Dependent on process parameters. Dependent on process parameters.
Batch size
  • Up to 4x6" wafers or
  • Up to 3x8" wafers
or
  • smaller pieces
  • Up to 1x8" wafer or 1x6" wafer
  • Up to 3x4" wafers
  • smaller pieces
  • 1x6" wafers or
  • 1x4" wafers or
  • smaller pieces
  • up to 10x6" wafers or
  • up to 10x4" wafers or
  • many smaller pieces
Allowed materials
  • Almost any as long as it does not outgas if you plan to use substrate heating. See cross-contamination sheets in Labmanager.
  • Almost any as long as it does not outgas. See cross-contamination sheet in Labmanager.
  • Almost any that does not degas at your intended substrate temperature. See cross contamination sheets for PC1 and PC3
Comment Pumpdown approx 20 min. Possible to tilt the wafer to achieve tunable step coverage. Pumpdown approx 15 min. Load and transfer < 10 minutes Load and transfer approx. 12 minutes
