Abstract
Embodiments of the present disclosure include a transistor with a vertical drift region and methods for forming the transistor. The transistor may include a well region of a first conductivity type, a gate region disposed above the well region, and a drift region of a second conductivity type, different from the first conductivity type. The drift region may have a lateral portion disposed above a portion of the well region and laterally adjacent to a semiconductor channel in the well region. The drift region may also have a vertical portion extending vertically from the lateral portion of the drift region.
