Gallium arsenide is currently one of the most important compound semiconductor materials with the highest mature epi wafer technology. GaAs material has the characteristics of large forbidden band width, high electron mobility, direct band gap, high luminous efficiency. Due to all all these epi wafer advantages, GaAs epitaxy is currently the most important material used in the field of optoelectronics. Meanwhile, it is also an important microelectronic material. According to the difference in electrical conductivity, GaAs epi wafer materials can be divided into semi-insulating (SI) GaAs and semiconductor (SC) GaAs.
In the field of epitaxial wafers, the epi wafer market share of RF and laser applications is very large.
