Abstract:
1. An electronic component, comprising: a depletion-mode transistor having a first breakdown voltage and a first maximum current level, the depletion-mode transistor comprising a source electrode, a gate electrode, a drain electrode, a semiconductor material layer, and a channel in the semiconductor material layer; and an enhancement-mode transistor having a second breakdown voltage and a second maximum current level, the enhancement-mode transistor comprising a source electrode, a gate electrode, and a drain electrode; wherein the source electrode of the depletion-mode transistor is electrically connected to the drain electrode of the enhancement-mode transistor and the gate electrode of the depletion-mode transistor is electrically coupled to the source electrode of the enhancement-mode transistor; and the semiconductor material layer of the depletion-mode transistor includes a recess in a gate region of the depletion-mode transistor, the recess causing a conductivity or charge density of the channel to be smaller in the gate region than in an access region of the depletion-mode transistor when 0V is applied to the gate electrode of the depletion-mode transistor relative to the source electrode of the depletion-mode transistor, the recess further causing the first maximum current level to be smaller than the second maximum current level.
