Claim 0:
1. A semiconductor device comprising:
a plurality of first electrode pads electrically connected to first electrodes of a transistor through a plurality of first electrode contact holes;
a plurality of second electrode pads electrically connected to second electrodes of the transistor through a plurality of second electrode contact holes;
a third electrode pad electrically connected to third electrodes of the transistor through a plurality of third electrode contact holes, the third electrodes controlling switching operation between the first electrodes and the second electrodes; and
a source field plate arranged between each of the first electrodes and each of the third electrodes, wherein
the plurality of first electrode pads, the plurality of second electrode pads, and the third electrode pad are arranged on one surface of the transistor,
the plurality of first electrode contact holes are divided into plural groups, the plural groups of the first electrode contact holes being spaced apart from each other in a first direction in a plan view, each group of the first electrode contact holes including a part of the plurality of first electrode contact holes arranged in a second direction that is orthogonal to the first direction in the plan view,
the plurality of second electrode contact holes are divided into plural groups, the plural groups of the second electrode contact holes being spaced apart from each other in the first direction, each group of the second electrode contact holes including a part of the plurality of second electrode contact holes arranged in the second direction,
the plurality of first electrode pads and the plurality of second electrode pads are alternately arranged in the first direction,
a distance between each of the third electrodes and each of the second electrode contact holes is shorter than a distance between each of the third electrodes and each of the first electrode contact holes, and
the source field plate includes an end portion having an arched shape.
