Abstract

A semiconductor device includes a chip, an electrode that is formed on the chip, an inorganic insulating layer that covers the electrode and has a first opening exposing the electrode, an organic insulating layer that covers the inorganic insulating layer, has a second opening surrounding the first opening at an interval from the first opening, and exposes an inner peripheral edge of the inorganic insulating layer in a region between the first opening and the second opening, and an Ni plating layer that covers the electrode inside the first opening and covers the inner peripheral edge of the inorganic insulating layer inside the second opening.
