VTT Niobium SWAPS Junction Process


This two-layer process allows for the fabrication of Niobium side-wall passivated junctions via an Nb-Al-AlOx-Nb tri-layer, alongside an Nb wiring layer on top. 

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

  • Nb-Al-ALOx-Nb trilayer junctions 
  • High-resistivity silicon substrate
  • Nb wiring layer on top

The process provides 20 copies of the designs.


  • Josephson junctions
  • SQUIDs
  • JPA (Josephson parametric amplifier)
  • Low-temperature electronics
  • Resonators
  • Qubits


  • Design kits
  • Design-rule checking services
  • CMC engineering support
