Patent ID: 7859111

Claim:
A semiconductor device comprising: a first wire; an interlayer dielectric disposed on the first wire; first and second via plugs buried in the interlayer dielectric connected to the first wire; a second wire disposed on the interlayer dielectric, the second wire oriented obliquely to a longitudinal direction of the first wire and intersects with the first wire where the first via plug is disposed; and a protrusion wire having a same wire width as the second wire, disposed on a same layer level as the second wire on the interlayer dielectric and oriented obliquely to the longitudinal direction of the first wire and oriented perpendicularly to a longitudinal direction of the second wire, wherein an end of the protrusion wire is connected to an end of the second wire on a same layer level as the second wire and another end thereof is connected only to the second via on the first wire, and wherein the first and second via plugs are provided away from a connected portion of the second wire and the protrusion wire, and wherein another end of the second wire extends beyond the first wire.
