Abstract:
1. A semiconductor device having a multi-bridge-channel, comprising: a first semiconductor post protruding a first predetermined height from a surface of a semiconductor substrate and having a source region in an upper side portion thereof; a second semiconductor post protruding a second predetermined height from the surface of the semiconductor substrate, the second semiconductor post facing the first semiconductor post and having a drain region in an upper side portion thereof; a pair of channel semiconductor layers connecting the upper side portion of the first semiconductor post to the upper side portion of the second semiconductor post; a gate insulation layer on the pair of channel semiconductor layers and the semiconductor substrate, the gate insulation layer surrounding at least a portion of the pair of channel semiconductor layers; a gate electrode layer on the gate insulation layer to enclose at least a portion of a region between the pair of channel semiconductor layers; and a pair of junction auxiliary layers formed between the pair of channel semiconductor layers, the pair of junction auxiliary layers contacting the gate electrode layer, the upper side portion of the first semiconductor post, and the upper side portion of the second semiconductor post, and having a same width as a width of the pair of channel semiconductor layers.
