customized orientation 2inch SSP Sapphire carrier substrate chip for GaN template grow application

Sapphire wafer carriers  are manufactured to exacting specifications and offer a stable carrier for processing GaAs,GaN,AlN and other semiconductors Template. 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.
