Patent ID: 8866231

Claim:
A nitride semiconductor device, comprising: a substrate; a nitride semiconductor layer formed over the substrate and including an active region; first electrode interconnect layers extending in parallel with one another over the active region of the nitride semiconductor layer and divided by areas extending on the nitride semiconductor layer across a longitudinal direction of the first electrode interconnect layers; first gate electrodes extending along the first electrode interconnect layers on the nitride semiconductor layer; first gate electrode connecting interconnects extending in associated ones of the areas dividing the first electrode interconnect layers and perpendicularly to a longitudinal direction of the first gate electrodes, and being in electrical connection to the first gate electrodes; first electrode connecting interconnects formed above the first gate electrode connecting interconnects and being in electrical connection to the first electrode interconnect layers; an interconnect insulating film formed over the first electrode interconnect layers and the first electrode connecting interconnects, and having openings, the first electrode connecting interconnects exposed through associated ones of the openings; and first electrode upper interconnects formed on the first electrode connecting interconnects with the interconnect insulating film interposed therebetween, and being in electrical connection to the first electrode connecting interconnects through the associated ones of the openings.
