摘要:
A semiconductor device includes first to third lines. The second line has a width equal to the first line. The second line is arranged with a space equal to the width from the first line, and partially has a gap. The third line is connected to one end of the first line and to a side of one end of the second line.

A semiconductor storage device has a sense amplifier. The sense amplifier includes a first lower interconnection; a second interlayer insulation film formed on the first interlayer insulation film and top of the first interconnection; a contact interconnection formed in a direction perpendicular to a substrate plane of the semiconductor substrate so as to pass through the second interlayer insulation film, and connected to the first lower interconnection; a first upper interconnection formed on the second interlayer insulation film and connected to the contact interconnection disposed under the first upper interconnection; a dummy contact interconnection formed in a direction perpendicular to the substrate plane of the semiconductor substrate in the second interlayer insulation film, and adjacent to the contact interconnection; and a second upper interconnection formed on the second interlayer insulation film so as to extend in the first direction, and connected to the dummy contact interconnection disposed under the second upper interconnection.
