发明名称 METHOD OF PRODUCING SEMICONDUCTOR WAFER AND SEMICONDUCTOR WAFER
摘要 A method of producing a semiconductor wafer includes placing a base wafer within a reaction chamber, and epitaxially growing a p-type Group 3-5 compound semiconductor on the base wafer by supplying, into the reaction chamber, a Group 3 source gas consisting of an organometallic compound of a Group 3 element, a Group 5 source gas consisting of a compound of a Group 5 element, and an impurity gas including an impurity that is to be incorporated as a dopant into a semiconductor to serve as a donor. Here, during the epitaxial growth of the p-type Group 3-5 compound semiconductor, the flow rate of the impurity gas and the flow rate ratio of the Group 5 source gas to the Group 3 source gas are set so that the product N×d (cm−2) of the residual carrier concentration N (cm−3) and the thickness d (cm) of the p-type Group 3-5 compound semiconductor may be 8.0×1011 or less.
