Wafers for research and development, equipment testing and evaluation

  • We provide high-quality wafers such as single-sided mirror wafers from 2 inches to 12 inches and oxide film wafers.
  • Depending on your needs, we can provide finishes such as square wafers, round wafers without OF (orientation flat), double-sided mirrors, double-sided etching, and double-sided wrapping.
  • Wafer thickness can be manufactured from 100 μm (4 inches) to 2,000 μm.

Wafers for sensors and MEMS

We provide high-precision wafers that can be used to create precise grooves for sensor and MESM applications, using deep etching processing.

  • Smaller surface orientation (cutting angle) tolerance
  • Smaller OF position angle tolerance
  • Smaller thickness tolerances
  • More accurate flatness
