Abstract: A method of oxidizing a substrate having area of about 30,000 mm2 or more. The surface is preferably comprised of silicon-containing materials, such as silicon, silicon germanium, silicon carbide, silicon nitride, and metal silicides. A mixture of oxygen-bearing gas and diluent gas normally non-reactive to oxygen, such as Ne, Ar, Kr, Xe, and/or Rn are ionized to create a plasma having an electron density of at least about 1 e12 cm?3 and containing ambient electrons having an average temperature greater than about 1 eV. The substrate surface is oxidized with energetic particles, comprising primarily atomic oxygen, created in the plasma to form an oxide film of substantially uniform thickness. The oxidation of the substrate takes place at a temperature below about 700° C., e.g., between about room temperature, 20° C., and about 500° C.

Abstract: The present invention provides a structure and method of forming vertical transistors. The structure of the present invention comprises: a substrate having an insulator layer formed thereon and a trench formed therein, the trench having an upper trench section extending through the insulator layer to an upper surface of the substrate and having a lower trench section extending from the upper substrate surface into the substrate; a semiconductor layer formed adjacent to the upper trench sidewalls; an upper terminal region and a lower terminal region formed in the semiconductor layer, where a channel region separates the upper terminal region from the lower terminal region; a gate insulator extending from the upper terminal region to the lower terminal region and in contact with the channel region; and a gate conductor formed on the gate insulator, the gate insulator isolating the gate conductor from the channel region.
