Patent ID: 7842951

Claim:
A transistor comprising: a control electrode formed on a substrate, the control electrode including a gate body portion, a first gate hand portion protruding from a first end of the gate body portion, and a second gate hand portion protruding from a second end of the gate body portion, the second gate hand portion being substantially parallel with the first gate hand portion; a first current electrode disposed between the first and second gate hand portions of the control electrode, the first current electrode being electrically insulated from the control electrode, the first current electrode partly overlapping with a portion of the control electrode; a second current electrode disposed over the control electrode and electrically insulated from the control electrode, the second current electrode partly overlapping with the first gate hand portion and the second gate hand portion of the control electrode; and a single unitary semiconductor layer including an active layer and an ohmic contact layer disposed on the active layer, the semiconductor layer being disposed between the control electrode and the first and second current electrodes, and overlapping an entire of the first current electrode disposed between the first and second gate hand portions of the control electrode, wherein the second current electrode partly surrounds the first current electrode to have a U-shape on the semiconductor layer disposed on the control electrode.
