Abstract

A multi-gate field effect transistor includes: a plurality of semiconductor layers arranged in parallel on a substrate; source and drain regions formed in each of the semiconductor layers; channel regions each provided between the source region and the drain region in each of the semiconductor layers; protection films each provided on an upper face of each of the channel regions; gate insulating films each provided on both side faces of each of the channel regions; a plurality of gate electrodes provided on both side faces of each of the channel regions so as to interpose the gate insulating film, provided above the upper face of each of the channel region so as to interpose the protection film, and containing a metal element; a connecting portion connecting upper faces of the gate electrodes; and a gate wire connected to the connecting portion.
