Abstract
In an embodiment, an apparatus includes a source region, a gate region and a drain region supported by a substrate, and a drift region including a plurality of vertically extending n-wells and p-wells to couple the gate region and the drain region of a transistor, wherein the plurality of n-wells and p-wells are formed in alternating longitudinal rows to form a superjunction drift region longitudinally extending between the gate region and the drain region of the transistor.
