Benchtop ALD - GEMStar XT-R Thermal ALD upgradeable to PEALD

Brand: Arradiance

Product Code: GEMStar XT-R

Availability: On Request

GEMStar XTTM family produces best in class ALD films from high aspect ratio particles through 200mm substrates both in single substrate and batch modes of operation

Not yet ready for PEALD development, the GEMStar XT-RTM Thermal Atomic Layer Deposition systems offers 300 °C (450 °C optional) ALD processing through the full range of substrates, including Solar Cell ALD development and the ability to upgrade to full Plasma Enhanced (PEALD) capability in the future!

Configured standard with either a single (S) or dual (D) 200 °C manifold zones, four (S) or eight (D) high speed material ALD valve ports (one with vapor push technology), two locatable 200 °C material temperature zones and an external gas interface, the GEMStar XT-RTM represents one of the most configurable systems in its price range.

Key System Features

  • Adjustable reactor temp up to 300°C
  • Up to 200°C uniform gas distribution delivery
  • Pulsed Vapor Push (PVPTM) to handle very low pressure material
  • Selectable flow-through and exposure modes of deposition
  • Substrate configurable end effectors up to 200 mm diameter substrates, batch cassette options as well as a heated platen
  • User selectable carrier gas MFC controlled input up to 200 SCCM
  • Field proven GEMFlowTM Control System
  • Watchdog protection and EMO interface
  • Operator touch safe exterior

Ease of Operation

The Arradiance GEMFlowTM Software provides complete user control over all key operating parameters such as temperature, gas flow rate, highspeed ALD valves, RF Power and vacuum isolation.

  • Preloaded on business level Windows® Laptop User created processes can be saved enabling substrate to substrate and batch to batch consistency without sacrificing flexibility
  • Diagnostic system and logging creates traceable data of all system parameters during operation
  • Internal GEMStar XT USB control module


Modular ergonomic design with top panel access to all critical components
