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 8):
The semiconductor device according to  claim 2 , wherein:\n the first interconnection includes a first tantalum film, each of the first groove-shaped vias includes a second tantalum film, the second interconnection includes a third tantalum film, the second tantalum film is integral with the third tantalum film, and each of the second groove-shaped vias include a titanium.
