Abstract:
1. A method of manufacturing a semiconductor device, comprising: a step of forming at least one of a protruding electrode and wiring on one surface of a semiconductor substrate; a step of forming a first resin film on the semiconductor substrate on the one surface on which at least one of the protruding electrode and the wiring is formed, the first resin film having elasticity low enough to reduce stress induced by a difference in thermal expansion coefficient between the semiconductor substrate and the first resin film; a grinding step of reducing the semiconductor substrate in thickness through one of polishing and grinding of the other surface of the semiconductor substrate; a step of forming a second resin film on the other surface subsequent to the grinding step, the second resin film having one of higher elasticity and higher hardness than the first resin film; and a step of cutting the semiconductor substrate into individual pieces after the second resin film is formed.
