An embodiment relates to a device comprising a first section and a second section. The first section comprises a first metal oxide semiconductor (MOS) interface comprising a first portion and a second portion. The first portion comprises a first contact with a horizontal surface of a semiconductor substrate and the second portion comprises a second contact with a trench sidewall of a trench region of the semiconductor substrate. The second section comprises one of a second metal oxide semiconductor (MOS) interface and a metal region. The second MOS interface comprises a third contact with the trench sidewall of the trench region. The metal region comprises a fourth contact with a first conductivity type drift layer. The first section and the second section are located contiguously within the device along a lateral direction.
