Issues for the larger diameter epitaxial wafer
In order to establish the epitaxial wafer as the main substrate for semiconductor devices produced on large diameter wafers over 300 mm, the epitaxial wafer must satisfy stringent requirements in terms of both quality and costs. Before proceeding [...]
Semiconductor GaAs materials are mainly used in optical communication active devices, semiconductor light emitting diodes (LEDs), high-efficiency solar cells, and Hall devices. Moreover, GaAs optoelectronic devices have important applications in household appliances, industrial instruments, large screen displays, office automation equipment, traffic management, etc. To [...]
