    • A compound semiconductor substrate and a method for controlling electric property thereof are provided to improve product reliability and application range by offering the compound semiconductor which may have the electrical property from high insulation to high conduction. A compound semiconductor substrate is prepared by forming point defects in a substrate by implanting an electrically-neutral impurity with energy of 0.1 to 10 MeV into the substrate. When the compound semiconductor is undoped, electrical resistance increases to increase insulating properties, and when the compound semiconductor is doped with an n-type dopant, the impurity is implanted and charge concentration of the substrate increases to increase conductive properties. The various electrical properties needed for the compound semiconductor can be effectively controlled by increasing the insulating properties of the undoped compound semiconductor or by increasing the charge concentration of the n-type compound semiconductor, and the application range to various devices can be expanded.
