  • Publication number: 20170271182
    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: 20170211175
    Abstract: Embodiments of a sputter source for semiconductor process chambers are provided herein. In some embodiments, a sputter source for a semiconductor process chamber may include: a target comprising a magnetic material to be deposited on a substrate, the magnetic material including a front surface where material is to be sputtered and an opposing back surface; and an outer magnet disposed proximate a back surface of the target and arranged symmetrically with respect to a central axis of the target, wherein the target has an annular groove formed in the back surface of the target disposed proximate the outer magnet to reduce a magnetic permeability of a region of the target proximate the outer magnet, wherein the groove is an unfilled v-shaped groove having an inner angle greater than 90 degrees.
