Abstract

According to one embodiment, a manufacturing method of a semiconductor device attained as follows. A dielectric layer having a first opening and a second opening reaching an electrode terminal is formed by modifying a photosensitive resin film on a substrate on which the electrode terminal of a first conductive layer is provided. Next, a second conductive layer that is electrically connected to the electrode terminal is formed on the dielectric layer that includes inside of the first opening, and a third conductive layer that has an oxidation-reduction potential of which difference from the oxidation-reduction potential of the first conductive layer is smaller than a difference of the oxidation-reduction potential between the first conductive layer and the second conductive layer is formed on the second conductive layer. Next, a dielectric layer having a third opening reaching the third conductive layer and a fourth opening reaching the electrode terminal via the second opening is formed by modifying a photosensitive resin film, and a bump that is electrically connected to the third conductive layer is formed.
