Abstract:
1. A semiconductor device, comprising: (a) a laterally diffused MISFET, including: (a2) a source region disposed in the semiconductor substrate on one side of the gate electrode, and a drain region disposed in the semiconductor substrate on the other side of the gate electrode; (b) a source contact 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 contact; (d) a drain contact 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 contact, wherein the drain contact includes a plurality of separated drain contacts disposed at first intervals in the first direction in the first region, wherein the source contact includes a plurality of separated source contacts disposed at the first intervals in the first direction in the second region, wherein each of the separated drain contacts is shifted in the first direction so as to be located between the separated source contacts in the first direction, wherein the drain wiring includes a plurality of separated drain wirings arranged at second intervals in the first direction in the first region, wherein the source wiring includes a cutout portion formed by causing one end of the source wiring on the drain contact side among ends thereof extending in the first direction to recede in a second direction intersecting the first direction, and wherein the cutout portion is disposed between the separated source contacts.
