Provided is a method of fabricating a transistor. The method includes forming a fin portion protruding upward from a substrate, forming a device isolation pattern on the substrate to cover a lower portion of a sidewall of the fin portion, forming a trench in the device isolation pattern, the trench exposing a top surface and sidewalls of a channel region of the fin portion, and injecting a Group-IV element into the channel region of the fin portion to increase the volume of the channel region.
