Back to Sapphire
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
