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

	E-beam evaporation (Alcatel)	E-beam evaporation (Wordentec)	Sputter (Lesker)	Sputter coater Hummer	Sputter coater Balzer
Batch size	Up to 1x4" wafers smaller pieces	24x2" wafers or 6x4" wafers or 6x6" wafers	up to 1x6" wafer	1x4" wafer Several smaller samples	1 large sample (< 4" wafer) Several smaller samples
Pre-clean	RF Ar clean	RF Ar clean	RF Ar clean
Layer thickness	10 Å to 5000Å*	10 Å to 5000Å*	10 Å to
Deposition rate	2 Å/s to 10 Å/s	1 Å/s to 10 Å/s		Not measured	Not measured

* For thicknesses above 200 nm permission from ThinFilm group (thinfilm@danchip.dtu.dk) is required.
