Abstract: A multi-gate transistor includes; a doped drain region; a doped source region; a gate group including a first gate and a second gate; a channel, the doped drain region and the doped source region being on respective two sides of the channel; and an interlayer, formed between the channel and the gate group, wherein a first gate voltage and a second gate voltage are applied to the first gate and the second gate of the gate group, respectively, the channel is induced as at least a P sub-channel and at least an N sub-channel and the multi-gate transistor equivalently behaves as a PNPN structure.
