Claim Text:
1. A semiconductor device, comprising: (a) a laterally diffused MISFET, including: (b) a source plug disposed in a second region located on the one side of the gate electrode over the semiconductor substrate to be electrically coupled to the source region; (c) a source wiring disposed over the source plug; (d) a drain plug disposed in a first region located on the other side of the gate electrode over the semiconductor substrate to be electrically coupled to the drain region; and (e) a drain wiring disposed over the drain plug, wherein the drain plug is linearly disposed in the first region to extend in the first direction in plan view, wherein the source plug includes a plurality of separated source plugs arranged at predetermined intervals in the first direction in the second region in plan view, wherein the source plugs include a first separated source plug column and a second separated source plug column, wherein the first separated source plug column includes a plurality of separated source plugs arranged at first intervals in the first direction, wherein the second separated source plug column includes a plurality of separated source plugs arranged in the first direction at third intervals smaller than the first intervals, and wherein the first separated source plug column is disposed closer to the drain plug side than to the second separated source plug column.
