GaN Wafer Characteristic
| Product | Gallium nitride (GaN) substrates |
| Product Description: | Saphhire GaN template is presented Epitxial hydride vapor phase epitaxy (HVPE) method. In the HVPE process, the acid produced by the reaction GaCl, which is in turn reacted with ammonia to produce gallium nitride melt. Epitaxial GaN template is a cost-effective way to replace gallium nitride single crystal substrate. |
