1. A method for making a high dielectric constant gate dielectric on a semiconductor substrate:

  • forming a layer of a silicon oxide layer at a high temperature over a semiconductor substrate, wherein the silicon oxide layer comprises a plurality of monolayers of silicon dioxide;

    removing a portion of the plurality of monolayers to leave at least one monolayer; and

    depositing a layer of high dielectric constant material over the at least one monolayer, wherein the high dielectric constant material is not in contact with the semiconductor substrate.
