Abstract:
1. A semiconductor device comprising: a first insulating film; a first interconnection formed in the first insulating film, the first interconnection extending in a first direction and having a first width in a second direction that is substantially perpendicular with the first direction; a second insulating film overlying the first insulating film; and a second interconnection formed in the second insulating film, the second interconnection having an interconnection portion having a first length in the second direction and a contact portion formed between the interconnection portion and the first interconnection, the contact portion having a second width in the second direction that is smaller than the first length and larger than the first width, and being in direct contact with an outer side surface and an upper surface of the first interconnection, the interconnection portion having a second length in the first direction, and the contact portion having a third length in the first direction that is not greater than the second length, wherein the interconnection portion and the contact portion are a same material and contiguous with respect to each other without an interface there between.
