GEMStar™ benchtop ALD systems, engineered for world-class performance.

The system behind hundreds of independently published studies. GEMStar runs thermal ALD, plasma-enhanced ALD, and MLD on wafers, powders, and 3D parts. Install on a bench, in a glovebox, or as part of a custom integrated process system.

The GEMStar family

Three reactor versions plus a glovebox-integrated option.

Start where your chemistry is today. Upgrade when it changes.

All GEMStar systems share the same proven core: configurable manifolds, heated precursor delivery up to 200 °C, Arradiance’s Pulsed Vapor Push (PVP™) for low-vapor-pressure precursors, and GEMFlow™ control software with real-time process history. Pick the variant that matches the process you’re running today, and you have a clear path to plasma-enhanced and oxygen-sensitive work as your roadmap grows.

Facilities & certification

Site-prep documents.

Physical dimensions, weights, electrical power, and gas requirements for each current GEMStar process system. All systems are CE-marked, “Watchdog”-protected, and shipped with an EMO interface. CSA certification is available on request.

Recommended pump package

ARR-EV-A10-P-EPP — engineered for GEMStar.

The Enhanced Dry Pump Package is the combination of the ARR‑EBARA EV-A10 dry pump and our ARR‑RD003000 dry-pump multi-trap. Engineered in partnership with critical suppliers for optimum process performance and low maintenance without sacrificing reliability.

This combination is what our own service chase runs — even under heavy use it has eliminated pump failures through unexpected power outages and factory shutdowns.
