发明名称 METHOD OF PRODUCING SEMICONDUCTOR WAFER, AND SEMICONDUCTOR WAFER
摘要 A method of producing a semiconductor wafer suited to form types of devices such as HBT and FET on a single semiconductor wafer is provided. The method, by repeating steps including introducing, into a reaction chamber for forming a semiconductor by crystal growth, a first-impurity gas containing an element or a compound containing a first impurity atom as a constituent, thereby producing semiconductor wafers, includes, after introducing the first-impurity gas: taking out a produced semiconductor wafer; disposing a first semiconductor in the reaction chamber; introducing, into the reaction chamber, a second-impurity gas containing an element or a compound containing, as a constituent, a second impurity atom exhibiting a conduction type opposite to the conduction type of the first impurity atom within the first semiconductor; heating the first semiconductor in an atmosphere of the second-impurity gas; and forming a second semiconductor on the heated first semiconductor by crystal growth.
