Resistive Transparent Oxide Coating:

  • Understand the fundamental characteristic of conductive coatings used for glass transparencies.
  • Understand the advantages/disadvantages of ITO vs TO and respective process comparisons.
  • Understand the advantages/disadvantages of ceramic vs allow target composition and effect from target wear characteristics.
  • Understand resultant crystalline structure of coatings.

Conductive Coating Thermal Performance:

  • Understand the heating characteristics of a resistive coating, including thermal performance and power density.
  • Understand how heater geometry affects uniformity.
  • Understand the usage of gradient coating application to control uniformity.

Vacuum Sputter Chamber:

  • Understand schematic and functional requirements of a vacuum sputter chamber including gas control and power supply control.
  • Understand monitoring systems and associated automated input/output controls.
