Abstract
An integrated circuit includes a fin having a height and a width under a gate of a selected fin-type field effect transistor (FinFET) that is less than the height and width along a remainder of the fin including under gates and for source/drain regions of other FinFETs. The IC includes a first FinFET having a first gate over a fin having a first height and a first width under the first gate, and a second FinFET in the fin adjacent to the first FinFET. The second FinFET has a second gate over the fin, and the fin has, under the second gate only, a second height less than the first height and a second width less than the first width. The resulting reduced channel height and width for the second FinFET increases gate control and reduces gate leakage, which is beneficial for ultra-low current leakage (ULL) devices.
