CASE 3: Trouble-shooting coating issues and providing solutions
  • Issue: There is a color issue in a customer's coating

  • Analysis: We did Optical Reverse Engineering indicated that there was a metalmigration into another layer by xx%.  

  • Solution: Research on a new barrier material

    • Software Designs a new coating stack

    • Stack deposition

    • Resolved the issue

case 4
CASE 4: Co-Sputter New Materials for a Biotech Research
  • A research group from One of largest biotech research company
    is looking for their samples response on new materials, 

  • Co-sputter new materials (C:A, C:B, A, B, C) for their research on wafer and glass substrate,

  • With a few thousand $ for a project (full set of samples), the cost is just like outsourcing a measurement, so that the P.O. is easily approved.

  • Successfully tested new materials for a new research project
