摘要: A method for forming an integrated circuit structure on a semiconductor substrate comprises depositing a high k gate dielectric material over the substrate using an atomic layer deposition process. A silicon oxide capping layer is deposited over the gate dielectric material in a rapid thermal chemical vapor deposition process. A gate electrode is formed over the silicon oxide capping layer.
