Abstract:
A semiconductor device comprising:a plurality of first transistors including a first gate electrode formed on a substrate through a first gate insulation film; a first insulation film formed on the first transistors and the substrate; a plurality of first wirings formed on the first insulation film, spaced from each other by a first gap; and a second wiring formed on the first insulation film, spaced from either of the first wirings by a second gap which is substantially equal to the first gap, the plurality of the first wirings being electrically connected to the plurality of the first gate electrodes of the plurality of the first transistors, respectively, the second wiring being electrically connected to the substrate without being electrically connected to the first transistors, and the second wiring being for use in electrical connections between the first gate electrodes and the substrate while forming the first wirings and the second wiring by etching a wiring material film.
