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.

The GEMStar XT-DPTM Plasma Enhanced Atomic Layer Deposition (PEALD) system extends the capabilities of the GEMStar XTTM Thermal system to include best in class plasma processing through the full range of substrates.

Configured with a 300 Watt air cooled direct Inductively Coupled Plasma (ICP) RF system with four mass flow controlled gas inputs, either 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-DPTM system is a powerful plasma enabled tool to extend your research and processing requirements to the next level.

Some key features of the system include:

  • 300-Watt Air Cooled Direct ICP
  • Head with four metal sealed mass flow-controlled plasma gas inputs
  • Adjustable reactor temperature up to 300°C Up to 200°C uniform gas distribution delivery
  • Pulsed Vapor Push (PVPTM) to handle very low pressure material
  • Substrate configurable end effectors up to 200 mm diameter substrates, as well as a 450°C heated platen option
  • User selectable carrier gas MFC controlled input up to 200 SCCM
  • Field proven GEMFlowTM Control System.

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

  • Fast precursor changes and reconfiguration
  • Easy access power, vacuum and gas connections
  • Perfectly suited for glove box configuration
