Abstract:
1. A semiconductor structure comprising: a semiconductor material layer located in a substrate; an insulator layer contacting a top surface of said semiconductor material layer and including a first opening and a second opening therein; a semiconductor fin contacting a top surface of said insulator layer; a gate stack contacting a top surface and sidewalls of said semiconductor fin; a source region filling said first opening, contacting a first portion of said top surface of said semiconductor material layer, and contacting a first end wall of said semiconductor fin that adjoins said sidewalls of said semiconductor fin; and a drain region filling said second opening, contacting a second portion of said top surface of said semiconductor material layer, and contacting a second end wall of said semiconductor fin that adjoins said sidewalls of said semiconductor fin, wherein a least lateral distance between said first portion of said top surface and said second portion of said top surface is greater than a lateral distance between said first end wall and said second end wall, and wherein a sidewall of said first opening adjoins said top surface of said insulator layer at a periphery that is laterally offset from said first end wall, and a sidewall of said second opening adjoins said top surface of said insulator layer at another periphery that is laterally offset from said second end wall.
