Abstract:
A transistor includes a semiconductor body; a first gate electrode formed on a first portion of the semiconductor body and a second gate electrode formed on a second portion of the semiconductor body. A drain region is formed on a first side of the first gate electrode and a first source region is formed on a second side of the first gate electrode. The drain region is formed on a first side of the second gate electrode and a second source region is formed on a second side of the second gate electrode. A trench is formed in the semiconductor body and positioned in the drain region. A doped sidewall region is formed in the semiconductor body along the sidewall of the trench outside of the trench. The doped sidewall region is in electrical contact with the drain region and forms a vertical drain current path for the transistor.

Claim (Index 1):
A transistor, comprising:\n a semiconductor body of a first conductivity type; a first gate electrode formed on a first portion of the semiconductor body and insulated from the semiconductor body by a gate dielectric layer, a drain region of a second conductivity type formed on a first side of the first gate electrode and a first source region of the second conductivity type formed on a second side of the first gate electrode, the second side opposite the first side; a second gate electrode formed on a second portion of the semiconductor body and insulated from the semiconductor body by the gate dielectric layer, the drain region being formed on a first side of the second gate electrode and a second source region of the second conductivity type formed on a second side of the second gate electrode; a trench formed in the semiconductor body and positioned in the drain region, the trench being lined with a thin dielectric layer as a sidewall dielectric layer, the trench is being filled with a bottom dielectric layer at a lower portion of the trench and a conductive layer above the bottom dielectric layer, the conductive layer being electrically connected to the gate electrode, wherein the first and second portions of the semiconductor body are on opposite sides of the trench; and a doped sidewall region of the second conductivity type formed in the semiconductor body along the sidewall of the trench outside of the trench, the doped sidewall region being in electrical contact with the drain region and forming a vertical drain current path for the transistor, the drain current of the transistor flowing in the doped sidewall region in the semiconductor body outside of the trench.
