Abstract
In a general aspect, a vertical transistor can include a semiconductor region of a first conductivity type, and a plurality of perpendicularly intersecting trenches having a shielded gate structure of the vertical transistor disposed therein. A mesa of the semiconductor region can be defined by the plurality of perpendicularly intersecting trenches. The mesa can include a proximal end portion having a first doping concentration of the first conductivity type, a distal end portion having the first doping concentration of the first conductivity type, and a central portion disposed between the proximal end portion and the distal end portion. The central portion can have a second doping concentration of the first conductivity type that is less than the first doping concentration.
