Sapphire Wafer Carriers
           
Back to Sapphire
           
           
Sapphire wafer carrier Sapphire wafer carriers are manufactured to your exacting specifications and offer a stable carrier for processing GaAs and other semiconductors. Sapphire wafer carriers are durable, chip, chemical and scratch resistant and will stand up to repeated use. Because of sapphire's extreme hardness, it will provide stronger and more durable carrier than quartz and other materials.
           
           
           
           
  We offer:

Diameters from 2" to 6"
Flatness and Parallelism to 0.005 mm
Optical grade High Purity Sapphire
Custom make hole sizes and patterns
Semi Standard Flats and laser marking available
