Abstract:
There is formed a first concave portion that extends inside a semiconductor substrate from a main surface thereof. An insulating film is formed over the main surface, over a side wall and a bottom wall of the first concave portion so as to cover an element and to form a capped hollow in the first concave portion. A first hole portion is formed in the insulating film so as to reach the hollow in the first concave portion from an upper surface of the insulating film, and to reach the semiconductor substrate on the bottom wall of the first concave portion while leaving the insulating film over the side wall of the first concave portion. There is formed a second hole portion that reaches the conductive portion from the upper surface of the insulating film. The first and second hole portions are formed by the same etching treatment.

Claim (Index 7):
A semiconductor device comprising:\n a semiconductor substrate that has a main surface and has a first concave portion formed so as to extend to an inside from the main surface; an element that has a conductive region located on the main surface of the semiconductor substrate; and an insulating film that is formed over the main surface so as to cover the element, is also formed over a side wall of the first concave portion in the first concave portion, and thereby is formed so as to expose the semiconductor substrate in a bottom wall of the first concave portion, wherein there is formed a first hole portion that reaches the bottom wall of the first concave portion through an inside of the first concave portion from an upper surface of the insulating film, and there is formed a second hole portion that reaches the conductive region from the upper surface of the insulating film, the semiconductor device further comprising: a first conductive layer formed in the first hole portion; and a second conductive layer formed in the second hole portion, and wherein the first conductive layer and the second conductive layer include a same material.
