Abstract:
1. A method of manufacturing a semiconductor device, including the steps of: (a) providing a substrate having an insulating top surface; (b) forming a fin of semiconductor material on the top surface of the substrate, the fin having first and second opposite sides; (c) forming at least one upstanding structure on each side of the fin laterally spaced from the respective side of the fin; (d) depositing a conformal layer of gate electrode material; (e) patterning the layer of gate electrode material; and (f) anisotropically etching away gate electrode material until the gate electrode material adjacent the first side of the fin is separated from the gate electrode material on the second side of the fin, the shortest distance between each upstanding structure and the respective side of the fin being less than twice the thickness of the conformal layer deposited in step (d).
