Patent ID: 8344463

Claim:
A bidirectional switch comprising: a plurality of unit cells including a semiconductor layer formed on a substrate, and a first ohmic electrode, a first gate electrode, a second gate electrode, and a second ohmic electrode successively formed on the semiconductor layer and spaced from each other; a first interconnection formed on the semiconductor layer, electrically connecting the first gate electrodes, and extending in a direction intersecting the first gate electrodes; a second interconnection formed on a side opposite to the first interconnection with the unit cells being interposed between the first and second interconnections, connecting the second gate electrodes, and extending in a direction intersecting the second gate electrodes; a first gate electrode pad electrically connected to the first interconnection; and a second gate electrode pad electrically connected to the second interconnection, wherein the entire first interconnection is overlapped by the first gate electrode pad in plan view, and the entire second interconnection is overlapped by the second gate electrode pad in plan view.
