Classification: CPC H | IPC H

Claim 15:
16. A method for modulating a drive current of a single-gate field effect transistor device, comprising:
forming a depletion-mode second channel in an active layer of the field effect transistor device when the transistor is turned off, the second channel dose not electrically connect with a source region and a drain region of the field effect transistor device; and
controlling at least one of a first channel and the second channel formed in the active layer to inject carriers into the other channel when the transistor is turned on, so that current conduction occurs between the source region and the drain region and carriers of the second channel contribute to an on-state current of the transistor; wherein the first channel and the second channel are of a same polarity.
