Claim Text:
1. A transistor device, comprising: a pillar of semiconductor material extending vertically from a bottom portion that is in contact with an electrically conductive contact line, wherein the electrically conductive contact line extends laterally past the pillar in a horizontal direction and contacts a sidewall of an electrically insulating line; a gate insulating liner layer on a lateral side of the pillar; a gate electrode on the gate insulating liner layer extending along the lateral side of the pillar; and a region of electrically insulating semiconductor oxide material filling a space between a bottom portion of the gate electrode and a top portion of the electrically conductive contact line and overlying the electrically conductive contact line and extending below a horizontal plane including a top surface of the electrically insulating line.
