  • Publication number: 20140269826
    Abstract: Disclosed are method and apparatus for treating a substrate. The apparatus is a dual-function process chamber that may perform both a material process and a thermal process on a substrate. The chamber has an annular radiant source disposed between a processing location and a transportation location of the chamber. Lift pins have length sufficient to maintain the substrate at the processing location while the substrate support is lowered below the radiant source plane to afford radiant heating of the substrate. One or more lift pins has a light pipe disposed therein to collect radiation emitted or transmitted by the substrate when the lift pin contacts the substrate surface.

  • Publication number: 20130330920
    Abstract: A high-frequency, hydrogen-based radio-frequency (RF) plasma is used to reduce a metal oxide and other contaminant disposed in an aperture that is formed in an ultra-low k dielectric material. Because the frequency of the plasma is at least about 40 MHz and the primary gas in the plasma is hydrogen, metal oxide can be advantageously removed without damaging the dielectric material.
