    摘要: A method of manufacturing a semiconductor device, includes a wafer grinding step of, by means of a revolving grinding stone, forming a thinned portion in a wafer while at the same time forming a slope surrounding said thinned portion, wherein during said formation of said slope, said grinding stone is positioned so that there is always a space between said slope and the facing side of said grinding stone, wherein said thinned portion is thinner than a peripheral portion of said wafer, and wherein said slope extends along and defines an inner circumferential side of said peripheral portion and forms an angle of 75° or more but less than 90° with respect to a main surface of said wafer. The method of manufacturing a semiconductor device further includes a step of forming a semiconductor device in said thinned portion.
