Deposition System Angstrom Quantum
Description
Superconducting materials deposition, sputtering and evaporation.
Manufacturer and Model
Angstrom-Quantum series
Technical specifications
- A three-chamber deposition cluster with a sputtering, an evaporation and an oxidation chamber
- Automated sample transfer across all chambers under vaccum
Base pressure < 5x10-9 Torr
The sputtering and evaporation chambers feature a sample heating up to 800°C and rotation
The evaporation chamber has sample tilt capability for liftoff JJ process
Can accommodate samples holders up to 200 mm wafer
This is a superconducting materials dedicated deposition tool, carrying Nb, Ta, Ti, and Al.
Exemples of available processes
Sputtering chamber : there are four targets inside the tool, and three different power sources for each. Targets can be operated using, a HIPIMS, DC-pulsed, or an RF power source.
The oxidation chamber allows, dynamic and static oxidation processes. And it has a turbo pump.
Evaporation chamber; the shadow evaporation lift-off process for Josephson junction fabrication is a great example that uses the tilt and rotation tool specifications
