摘要：
A manufacturing of a semiconductor device includes forming one of a layer with a first metal and the layer with a second metal on one of a semiconductor chip mounting area of a support plate and a back surface of the semiconductor chip; forming the other of the layer with the first metal and the layer with the second metal on an area corresponding to a part of the area, in which one of the layer with the first metal and the layer with the second metal, of the other one of the semiconductor chip mounting area and the back surface of the semiconductor chip; and forming a layer which includes an alloy with the first metal and the second metal after positioning the semiconductor chip in the semiconductor chip mounting area to bond the semiconductor chip with the semiconductor chip mounting area.
