Foundry · Custom wafer runs

Your design, our process, a full wafer of your own.

Dedicated wafer runs for teams who need their own layout, process choices and timeline. For prototyping on a shared wafer, see Q-MPW.

How a run works

From GDS to chips

  1. Scope call

    You tell us what you're building; we tell you what's realistic and what it costs. Pricing is based on the process steps your design needs.

  2. NDA and design hand-over

    GDS files, design notes, target parameters.

  3. Design review

    We check manufacturability and flag risks before anything is patterned.

  4. Fabrication

    In the Chalmers or DTU cleanroom.

    Standard lead time: 12–16 weeks

  5. Test and delivery

    Junction data and test results with every delivery.

    Included: room-temperature junction-resistance map and a delivery report

Your design stays yours

We sign an NDA before you send a single file. Only your team and our foundry see your design. Wafer previews show your chips and nothing else, and design data is handled on a need-to-know basis.

Shipping and export control

Our quantum devices are EU dual-use items (category 3A001). Every order needs a signed End-User Statement before shipping. Within the EU, and to Australia, Canada, Iceland, Japan, Liechtenstein, New Zealand, Norway, Switzerland, the UK and the US, no individual licence is needed. Anywhere else needs an export licence, which adds time, so tell us your destination early and we'll start the paperwork with you.

Send us what you're building.

A short description is enough to start. Attach a GDS file if you have one.
