This electron-beam evaporation system is the newest of the lab for metal deposition. This system is a bell-jar type system and has the capability to do up to 10-4” wafers in a lift-off configuration and up to 24-4” wafers in a sidewall coverage configuration. Rotational motion in combination with baffling is used for lift-off and provides roughly 5% uniformity across a 4” wafer. The sidewall coverage fixturing uses full planetary motion to provide coverage over all sidewalls. The system also an 8-pocket e-beam source and an Inficon IC/5 deposition controller that allows for programming of fully automated multiple layer depositions. The metals available for deposition are Al, Ti, Au, Pt, Ni, Pd, Ag, Ge, Fe, NiCr, NiFe and Cr. This system is used for n-type ohmic contact metalization to compound semiconductors, Schottky contacts to semiconductors, bond pads, and other general metalizations. The maximum deposition thickness during a run is limited to 1.0 microns.

About

This electron-beam evaporation system is a bell-jar type system and has the capability to do up to 9-4” wafers in a lift-off configuration and up to 18-4” wafers in a sidewall coverage configuration. Rotational motion in combination with baffling is used for lift-off and provides roughly 5% uniformity across a 4” wafer. The sidewall coverage fixturing uses full planetary motion to provide coverage over all sidewalls. The system also an 8-pocket e-beam source and an Inficon IC/5 deposition controller that allows for programming of fully automated multiple layer depositions. The metals available for deposition are Al, Ti, Au, Pt, Ni, Pd, Ag, Ge, Fe, NiCr, NiFe and Cr. This system is used for n-type ohmic contact metalization to compound semiconductors, Schottky contacts to semiconductors, bond pads, and other general metalizations. The maximum deposition thickness during a run is limited to 1.0 microns.
