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 4):
The method for manufacturing the semiconductor device according to  claim 2 ,\n wherein the semiconductor substrate has first and second element formation regions that are located apart from each other, and a first active barrier region that is located between the first and second element formation regions, the method further comprising the steps of: forming a first conductive-type first region in the semiconductor substrate so as to extend from the first element formation region at least to the second element formation region through the active barrier region; forming a second conductive-type second region on the main surface of the active barrier region so as to constitute p-n junction with a first conductive-type region including the first region; and forming a coupling conductive layer that is located over the main surface and electrically couples the first conductive layer to the second region, and wherein the first conductive layer is formed so as to reach the first region in the active barrier region.
