Patent ID: 7498616

Claim:
A field effect transistor comprising: a compound semiconductor substrate; a plurality of source electrodes elongated in a first direction; a plurality of drain electrodes elongated in the first direction, the source electrodes and the drain electrodes being positioned alternatively with respect to a second direction; a source wiring electrode formed on the substrate and connecting the source electrodes; a drain wiring electrode formed on the substrate and connecting the drain electrodes; and a gate wiring electrode formed on the substrate and comprising a first gate wiring portion disposed parallel to the second direction and a plurality of second gate wiring portions extending from the first gate wiring portion in the first direction, wherein each of the second gate wiring portions is disposed between a corresponding source electrode and a corresponding drain electrode, and said each of the second gate wiring portions bends in the second direction to cover an end portion of the corresponding source electrode or the corresponding drain electrode.
