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： Methods for forming semiconductor devices are provided. A semiconductor substrate is etched such that the semiconductor substrate defines a trench and a preliminary active pattern. The trench has a floor and a sidewall. An insulating layer is provided on the floor and the sidewall of the trench and a spacer is formed on the insulating layer such that the spacer is on the sidewall of the trench and on a portion of the floor of the trench. The insulating layer is removed on the floor of the trench and beneath the spacer such that a portion of the floor of the trench is at least partially exposed, the spacer is spaced apart from the floor of the trench and a portion of the preliminary active pattern is partially exposed. A portion of the exposed portion of the preliminary active pattern is partially removed to provide an active pattern that defines a recessed portion beneath the spacer. A buried insulating layer is formed in the recessed portion of the active pattern. Related devices are also provided.

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.
