Abstract

A semiconductor device and a manufacturing method thereof are provided. The fin semiconductor device includes a fin formed on a substrate and an insulating material layer formed on the substrate and surrounding the fin. The fin has a semiconductor layer that has a source region portion and a drain region portion. The fin includes a first channel control region, a second channel control region, and a channel region between the two channel control regions, all of which are positioned between the source region portion and the drain region portion. The two channel control regions may have the same conductivity type, different from the channel region.
