    摘要: Methods of fabricating an oxide layer on a semiconductor substrate are provided herein. In some embodiments, a method of forming an oxide layer on a semiconductor substrate includes placing a substrate to be oxidized on a substrate support in a vacuum chamber of a plasma reactor, the chamber having an ion generation region remote from the substrate support; introducing a process gas into the chamber, the process gas comprising at least one of hydrogen (H2) and oxygen (O2)—provided at a flow rate ratio of hydrogen (H2) to oxygen (O2) of up to about 3:1—or water vapor (H2O vapor); and generating an inductively coupled plasma in the ion generation region of the chamber to form a silicon oxide layer on the substrate.

    摘要: A method and apparatus for igniting a gas mixture into plasma using capacitive coupling techniques, shielding the plasma and other contents of the plasma reactor from the capacitively-coupled electric field, and maintaining the plasma using inductive coupling are provided. For some embodiments, the amount of capacitive coupling may be controlled after ignition of the plasma. Such techniques are employed in an effort to prevent damage to the surface of a substrate from excessive ion bombardment caused by the highly energized ions and electrons accelerated towards and perpendicular to the substrate surface by the electric field of capacitively-coupled plasma.

    摘要: The present invention generally provides methods and apparatuses that are adapted to form a high quality dielectric gate layer on a substrate. Embodiments contemplate a method wherein a metal plasma treatment process is used in lieu of a standard nitridization process to form a high dielectric constant layer on a substrate. Embodiments further contemplate an apparatus adapted to “implant” metal ions of relatively low energy in order to reduce ion bombardment damage to the gate dielectric layer, such as a silicon dioxide layer and to avoid incorporation of the metal atoms into the underlying silicon. In general, the process includes the steps of forming a high-k dielectric and then terminating the surface of the deposited high-k material to form a good interface between the gate electrode and the high-k dielectric material. Embodiments of the invention also provide a cluster tool that is adapted to form a high-k dielectric material, terminate the surface of the high-k dielectric material, perform any desirable post treatment steps, and form the polysilicon and/or metal gate layers.
