Abstract
In a general aspect, a semiconductor device can include a gate having a first trench portion disposed within a first trench of a junction field-effect transistor device, a second trench portion disposed within a second trench of the junction field-effect transistor device, and a top portion coupled to both the first trench portion and to the second trench portion. The semiconductor device can include a mesa region disposed between the first trench and the second trench, and including a single PN junction defined by an interface between a substrate dopant region having a first dopant type and a channel dopant region having a second dopant type.
