A manufacturing method for semiconductor devices includes a process of forming a conductive layer 4 on the other principle surface of a semiconductor wafer 10 having circuit elements 2 formed in one principle surface of the semiconductor wafer, a process of forming a protecting layer 5 on at least a part of the conductive layer, the protecting layer 5 being made from material having hard-to-shave characteristics in comparison with the conductive layer and a process of cutting the semiconductor wafer 10 into pieces with respect to each of the semiconductor devices 1 . By the manufacturing method, each semiconductor device 1 is provided with a semiconductor substrate 3 having the circuit elements 2 formed in one principle surface of the semiconductor substrate 3 , the conductive layer 4 formed on the other principle surface of the semiconductor substrate 3 and the protecting layer 5 formed on the conductive layer 4 in lamination to have hard-to-shave characteristics in comparison with the conductive layer 4.
