Claim:
1. A manufacturing method of a semiconductor device, comprising the steps of: (a) preparing a semiconductor substrate having a first face and a second face opposite to the first face; (b) forming a first element part and a second element part in respective regions different from each other in the first face of the semiconductor substrate; (c) after the step (b), forming a wiring in the second element part; and (d) after the step (c), mounting the semiconductor substrate in a plasma apparatus provided with an upper electrode and a lower electrode facing each other, over the lower electrode, while bringing the lower electrode and the second face of the semiconductor substrate into contact with each other, so as to generate hydrogen plasma between the first face of the semiconductor substrate and the upper electrode, wherein the step (d) further includes the steps of:
