FAB

VTT Aluminum Junction Process

Description

This process allows for fabrication of coplanar structures on a high-resistivity silicon substrate, like resonators with quality factors of about one million. Aluminum junctions (Manhattan style) fabricated via electron-beam lithography can be used to make transmon qubits.

CMC offers this process as part of a multi-project wafer (MPW) service.
