What It Is
A multi-project wafer service lets several designs share one wafer run. SkyWater’s page, reviewed on 25 October 2026, describes that service for prototyping, IP verification, and device characterization, and it names S90LN and RH90 shuttle programs. The same company also has a separate RH90 process listing. The shuttle is the fabrication service. RH90 is the process. Neither listing is a piece of fabrication equipment.
The SkyWater page tells a user to discuss the project, download a PDK, and submit GDS for a scheduled shuttle. The PDK file was not downloaded for this guide. The page listed 2026 windows for S130, S90LN, and RH90. Those dates can change.
Why It Matters
A team choosing an early silicon run needs the shuttle schedule and the process it uses, rather than a process-node page alone.
What to Watch
Confirm the open GDS window, which process the shuttle uses, what the PDK includes, and whether the design rules match the separate process listing. Silicon Showcase reviewed the SkyWater page on 25 October 2026. The page does not show a provider publication date.
