NanoFab Tool: Denton Vacuum Discovery 550 Sputtering System 2

Photograph of the Denton Vacuum Discovery 550 sputtering system.

The Denton Vacuum Discovery 550 sputtering system has two direct current (DC) and two radio frequency (RF) sputtering guns which bombard targets, causing atoms to be ejected in order to support a wide range of thin film deposition processes. Both DC guns are magnetically enhanced to allow for deposition of ferromagnetic materials. A computer controlled user interface enables unattended sequencing of multiple deposition layers. The system has a heated, rotating stage for superior stress control and uniformity on substrates ranging from 150 mm diameter wafers down to small pieces.

Specifications/Capabilities

  • Turbo-pumped vacuum chamber has a base vacuum of 2.6 x 10-5 Pa (2 x 10-7 Torr).
  • Rotating stage for high uniformity deposition of thin films.
  • Stage temperature range: 25 °C to 350 °C.
  • 600 W DC and RF power supplies.
  • Two RF and two DC guns.
  • Both DC guns are magnetically enhanced for ferromagnetic materials.
  • Computer controlled interface enables unattended sequencing of multiple deposition layers.
  • Co-sputtering capability from one RF and one DC gun.
  • Argon bombardment can be used to remove native oxide from wafers.
  • Oxygen and nitrogen available for reactive sputtering.
  • Over 40 sputter targets provided by the NanoFab including most common metals and dielectrics; contact our engineers for more information.
