    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: A method and apparatus that provides process monitoring within a semiconductor wafer processing system using multiple process parameters. Specifically, the apparatus analyzes multiple process parameters and statistically correlates these parameters to detect a change in process characteristics such that the endpoint of an etch process may be accurately detected, as well as detecting other characteristics within the chamber. The multiple parameters may include optical emissia, environmental parameters such as pressure and temperature within the reaction chamber, RF power parameters such as reflected power or tuning voltage, and system parameters such as particular system configurations and control voltages.
