Abstract:
Methods of and apparatuses for dicing semiconductor wafers, each wafer having a plurality of integrated circuits, are described. In an example, a plasma thermal shield for a plasma processing chamber includes an annular ring body having an inner opening. A plasma-facing surface of the annular ring body has a general topography. A bottom surface of the annular ring body reciprocates the general topography with recessed regions disposed therein, providing one or more protruding regions at the bottom surface of the annular ring body.
Abstract:
Embodiments of methods and apparatus for processing a substrate are provided herein. In some embodiments, a process kit for a substrate process chamber may include a ring having a body and a lip extending radially inward from the body, wherein the body has a first annular channel formed in a bottom of the body; an annular conductive shield having a lower inwardly extending ledge that terminates in an upwardly extending portion configured to interface with the first annular channel of the ring; and a conductive member electrically coupling the ring to the conductive shield when the ring is disposed on the conductive shield.
Abstract:
A plasma processing apparatus (200) is disclosed. The plasma processing apparatus includes a source (206) configured to generate a plasma (140) in a process chamber (202) having a plasma sheath (242) adjacent to the front surface of a workpiece (138), and a plasma sheath modifier (208). The plasma sheath modifier controls a shape of a boundary (241) between the plasma and the plasma sheath so a portion of the shape of the boundary is not parallel to a plane (151) defined by a front surface of the workpiece facing the plasma. A metal target (209) is affixed to the back surface of the plasma sheath modifier so as to be electrically insulated from the plasma sheath modifier and is electrically biased such that ions (102) exiting the plasma and passing through an aperture in the plasma sheath modifier are attracted toward the metal target. These ions cause sputtering of the metal target, allowing three dimensional metal deposition of the workpiece.

Abstract:
Embodiments of the invention generally provide a processing chamber used to perform a physical vapor deposition (PVD) process and methods of depositing multi-compositional films. The processing chamber may include: an improved RF feed configuration to reduce any standing wave effects; an improved magnetron design to enhance RF plasma uniformity, deposited film composition and thickness uniformity; an improved substrate biasing configuration to improve process control; and an improved process kit design to improve RF field uniformity near the critical surfaces of the substrate. The method includes forming a plasma in a processing region of a chamber using an RF supply coupled to a multi-compositional target, translating a magnetron relative to the multi-compositional target, wherein the magnetron is positioned in a first position relative to a center point of the multi-compositional target while the magnetron is translating and the plasma is formed, and depositing a multi-compositional film on a substrate in the chamber.
