Inductively Coupled Plasma Chemical Vapour Deposition (ICPCVD)

Creation of high density plasmas in the ICP source means this technique delivers deposition of high quality dielectric films at low temperature with low damage. Low temperature deposition means that temperature sensitive films and devices can be processed successfully.

Our ICP CVD process modules are designed to produce high
quality films with high density plasmas at low deposition
pressures and temperatures.

Highlights

  • Independent control of ion energy and ion current density
  • Typical process pressure: 1- 10 mtorr
  • Plasma density: >1011 cm-3
  • Plasma in contact with the substrate
  • Low energy ion current during deposition
  • Ion Current (Plasma Density) dependent on ICP power
  • ESS (electrostatic screen) for a purely inductive plasma
  • ICP is fully automatic (2 RF automatch units)

Our ICPCVD cleaning regime was developed to give reproducible deposition and low particles between mechanical cleans

  • Reduced cleaning time
  • Higher utilisation through optional interleaved clean
  • Accurate endpoint resulting in reduced over-etch of chamber components and increasing their lifetime

High Rate Clean Process Features

  • System Utilisation >70%
  • SF6 /N2O gas mixture
  • Improved End Point control
  • Plasma clean results in increased optical intensity with greater endpoint signal/resolution
  • Actual plasma clean time depends on film material, film quality and film thickness

Interleaved Clean Mode 

  • High utilisation
  • Highly repeatable deposition rate
  • Low added particle counts maintained with clean after every wafer
  • > 50 microns between mechanical cleans
