Patent ID: 7285867

Claim:
A semiconductor device comprising: a semiconductor substrate having a plurality of connecting pads on one surface; an insulating film which is formed of a single layer and covers said one surface of the semiconductor substrate, and which includes: (i) a plurality of holes extending through the insulating film, each of the holes corresponding to one of the connecting pads, and (ii) at least one recess extending partially through the insulating film such that a bottom surface of the recess is depressed with respect to an upper surface of the insulating film in a direction of thickness of the insulating film, each said recess including a first portion through which one of the holes extends and which surrounds a periphery of the one of the holes and a second portion which extends outwardly from the first portion; and at least one interconnection including at least one conductive layer having: (i) a first section formed on the bottom surface of a corresponding said at least one recess to extend along the bottom surface, over the first portion and the second portion of the recess, and (ii) a second section that is directly contacted to a corresponding one of the connecting pads through a corresponding one of the holes in the insulating film, said at least one conductive layer being formed of a same material along an entire length thereof, including the first section and the second section.
