    摘要： Integrated circuit field effect transistors include an integrated circuit substrate and a fin that projects away from the integrated circuit substrate, extends along the integrated circuit substrate, and includes a top that is remote from the integrated circuit substrate. A channel region is provided in the fin that is doped a conductivity type and has a higher doping concentration of the conductivity type adjacent the top than remote from the top. A source region and a drain region are provided in the fin on opposite sides of the channel region, and an insulated gate electrode extends across the fin adjacent the channel region. Related fabrication methods also are described.

    摘要： A method of forming a fin field effect transistor on a semiconductor substrate includes forming a vertical fin protruding from the substrate. A buffer oxide liner is formed on a top surface and on sidewalls of the fin. A trench is then formed on the substrate, where at least a portion of the fin protrudes from a bottom surface of the trench. The trench may be formed by forming a dummy gate on at least a portion of the fin, forming an insulation layer on the fin surrounding the dummy gate, and then removing the dummy gate to expose the at least a portion of the fin, such that the trench is surrounded by the insulation layer. The buffer oxide liner is then removed from the protruding portion of the fin, and a gate is formed in the trench on the protruding portion of the fin.
