Abstract
A semiconductor device includes an active area extending in a first direction over a substrate, the active area including at least one conductive path extending from a source region, through a channel region, to a drain region; and a gate dielectric on a surface of the at least one conductive path in the channel region. The semiconductor device also includes an isolating fin at a first side of the active area, the isolating fin having a first fin region having a first fin width adjacent to the source region, a second fin region having a second fin width adjacent to the channel region, and a third fin region having the first fin width adjacent to the drain region; and a gate electrode against the gate dielectric in the channel region.
