Abstract
An integrated circuit transistor is formed on and in a substrate. A trench in the substrate is at least partially filed with a metal material to form a source (or drain) contact buried in the substrate. The substrate further includes a source (or drain) region epitaxially grown above the source (or drain) contact. The substrate further includes a channel region adjacent to the source (or drain) region. A gate dielectric is provided on top of the channel region and a gate electrode is provided on top of the gate dielectric. The substrate is preferably of the silicon on insulator (SOI) type.
