摘要
A process for LT-GaAs used as photoconductive switch in epitaxial layer transfer of on-chip THz antenna integrated device was provided. Hall indicated resistivity of the epitaxial materials gained by MBE was about 106Ω·cm. HNO3-NH4OH-H2O-C3H8O7·H2O-H2O2-HCl and wet chemical etching were used to etch epitaxial materials grown by MBE. Gained the structure that 1.5μm LT-GaAs bounded with COP after lift-off of SI-GaAs and Al0.9Ga0.1As. AFM, SEM and high-power microscope indicated that the structure was flat and smooth after lift-off. RMS=2.28 nm. EDAX indicated there wasn't Al in this structure. It can be used to make photoconductive switch.
