Abstract:
1. A semiconductor device, comprising: a first wire disposed in a first wiring layer, a second wire disposed in a second wiring layer stacked over the first wiring layer, a gate electrode arranged between the first wire and the second wire in a direction of stacking of the first wiring layer and the second wiring layer, and not coupled with the first wire and the second wire, a gate insulation film disposed over a side surface of the gate electrode, a semiconductor layer disposed over the side surface of the gate electrode via the gate insulation film, and coupled with the first wire and the second wire, a via disposed under the second wire, and coupled with the second wire, a second insulation film disposed between the gate electrode and the first wire, and a third insulation film disposed between the gate electrode and the via, wherein a film thickness of the second insulation film is larger than a film thickness of the third insulation film.
