Semiconductor device including a local wiring connecting diffusion regions

摘要

A semiconductor device has first conductivity type regions extending in a first direction, and second conductivity type regions extending in the first direction. The first conductivity type regions and the second conductivity type regions are alternately arranged in a second direction perpendicular to the first direction. The semiconductor device includes a first impurity diffused regions formed in the first conductivity type regions, a first local wiring connected to the first conductivity type regions, and extending in the second direction, a first potential supply wiring formed above the first local wiring, and extending in the first direction, and a first contact hole for connecting the first local wiring to the first potential supply wiring.
