A device is disclosed including one or more field effect transistors, each field effect transistor including: an elongated drain contact line including an electrically conductive material extending along a first horizontal direction; a drain including a first conductivity type semiconductor region overlaying the drain contact line; a source including a the first conductivity type semiconductor region located above the drain; and a gate extending vertically between the drain and the source. Each field effect transistor may include a first channel and a second channel, each including a second conductivity type |
