Abstract:
Disclosed herein is a semiconductor device including: a substrate having a first conductive layer and a second conductive layer arranged deeper than the first conductive layer; a large-diameter concave portion having, on a main side of a substrate, an opening sized to overlap the first and second conductive layers, with the first conductive layer exposed in part of the bottom of the large-diameter concave portion; a small-diameter concave portion extended from the large-diameter concave portion and formed by digging into the bottom of the large-diameter concave portion, with the second conductive layer exposed at the bottom of the small-diameter concave portion; and a conductive member provided in a connection hole made up of the large- and small-diameter concave portions to connect the first and second conductive layers.

Claim (Index 3):
A manufacturing method of a semiconductor device comprising:\n forming, on a main side of a substrate having a first conductive layer and a second conductive layer arranged deeper than the first conductive layer, a large-diameter resist pattern having an opening that exposes the tops of the first and second conductive layers; forming, in the substrate, a large-diameter concave portion having the first conductive layer exposed at the bottom based on etching using the large-diameter resist pattern as a mask; forming, on the main side of the substrate, a small-diameter resist pattern having an opening that exposes the top of the second conductive layer within the area where the large-diameter concave portion is formed; and forming, in the substrate, a small-diameter concave portion having the second conductive layer exposed at the bottom based on etching using the small-diameter resist pattern as a mask.
