Tutorial Lecture

Topic:

Control of Microstructure Evolution During Sputter Deposition

Time/Date/Place:

10:40-12:00, Oct. 27, Room 204

Summary

This module will elucidate the fundamental processes of film nucleation and growth and how they can be manipulated by low-energy metal and gas ion fluxes to achieve high-quality films at low deposition temperatures.

Topics

  • Film growth processes-nucleation, coalescence, competitive grain growth, recrystallization
    • Zone diagrams
    • Effects of sputtered atoms energy
    • Effects of reactive species.
    • Texture inheritance
    • Metal-ion etch and adhesion control
    • Kinetic roughing and surface facet formation
  • Use of low-energy ion bombardment to control microstructure during low temperature film growth
    • Effects of gas-ion energy
    • Use of high fluxes of low-energy gas ions; low-temperature sputter epitaxy
    • HiPIMS – source of energetic metal ions
    • Use of synchronized bias in HIPIMS
    • Hybrid HiPIMS/DCMS co-sputtering
      • Ligh metal-ions; supersaturated metastable TM nitrides
      • Heavy metal ions; low temperature, dense, stress-free hard coatings
