5*10mm2 SP-face (11-12) Un-doped SI-type free-standing GaN single crystal substrate Resistivity > 106 Ω·cm RF devices wafer
Overview
The GaN semiconductor device market includes key companies such as Cree, Infineon Technologies, Qorvo, MACOM, NXP Semiconductors, Mitsubishi Electric, Efficient Power Conversion (EPC), GaN Systems, Nichia Corporation, and Epistar Corporation.
Thin Epi wafers are commonly used for leading edge MOS devices. Thick Epi or Multi-layered epitaxial wafers are used for the devices mainly to control electric power, and they are contributing to improving the efficiency of energy consumption.

Appendix: The diagram of miscut angle
If δ1= 0 ±0.5°, then (11-22) plane off angle toward M-Axis is 0 ±0.5°.
If δ2= - 1 ±0.2°, then (11-22) plane off angle toward C-Axis is - 1 ±0.2°.
