Abstract:
The semiconductor device has insulating films  40, 42  formed over a substrate  10 ; an interconnection  58  buried in at least a surface side of the insulating films  40, 42 ; insulating films  60, 62  formed on the insulating film  42  and including a hole-shaped via-hole  60  and a groove-shaped via-hole  66 a  having a pattern bent at a right angle; and buried conductors  70, 72 a  buried in the hole-shaped via-hole  60  and the groove-shaped via-hole  66 a . A groove-shaped via-hole  66 a  is formed to have a width which is smaller than a width of the hole-shaped via-hole  66 . Defective filling of the buried conductor and the cracking of the inter-layer insulating film can be prevented. Steps on the conductor plug can be reduced. Accordingly, defective contact with the upper interconnection layer and the problems taking place in forming films can be prevented.

Claim (Index 1):
A semiconductor device comprising:\n a rectangular semiconductor substrate that includes four corners; a first interconnection formed above the rectangular semiconductor substrate; a guard ring that includes a plurality of first groove-shaped vias formed above the first interconnection; and a second interconnection formed above the plurality of first groove-shaped vias, wherein: the first interconnection includes copper; the first groove-shaped vias include copper; the second interconnection includes copper; the plurality of first groove-shaped vias are connected to the first interconnection; the plurality of first groove-shaped vias are integral with the second interconnection; each of the plurality of first groove-shaped vias includes a first pattern bent twice each time at an inner angle of larger than 90 degrees at each of the four corners in a plan view and bent totally at 90 degrees at each of the four corners in a plan view.
