Abstract: In plasma doping a non-planar semiconductor device, a substrate having a non-planar semiconductor body formed thereon is obtained. The substrate having the non-planar semiconductor body may be placed into a chamber. A plasma may be formed in the chamber and the plasma may contain dopant ions. A first bias voltage may be generated to implant dopant ions into a region of the non-planar semiconductor body. A second bias voltage may be generated to implant dopant ions into the same region. In one example, the first bias voltage and the second bias voltage may be different.

Abstract: Polishing pads are provided for a linear chemical mechanical polishing apparatus used in manufacturing integrated circuits. The polishing pads, which are attached to a polishing belt, are grooved in patterns to advantageously transport slurry from the point of introduction to the point at which semiconductor wafers are polished. The patterns include at least one set of multiple parallel grooves extending across the polishing pads. The grooves form an angle with the direction of travel of the belt that is unequal to zero.

Abstract: Slurry is provided to the surface of the polishing pad by pumping the slurry up through a central port, or by dripping the slurry down onto the surface of the polishing pad from a slurry feed tube. A slurry wiper, which may have one or more flexible members, sweeps the slurry evenly and thinly across the polishing pad. A control system coordinates the distribution of slurry to the polishing pad with the motion of the carrier head.

Abstract: A chemical mechanical polishing apparatus including a carrier head having an integral conditioning member is described. The conditioning member includes a conditioning surface that may selectively be moved into contact with a polishing surface of a polishing pad. The conditioning member may be connected to a surface of the carrier's retaining ring assembly. As a result, the polishing surface may be conditioned either continuously or intermittently when a substrate is loaded in the carrier for polishing.

Abstract: A wafer polishing apparatus includes a module frame; a continuous belt rotatable with respect to the frame, the belt having at least one vertically-oriented belt transverse portion including a polishing pad assembly; and at least one pivotable wafer-holding head drive within the frame and having a distal end portion movable to a vertical first position parallel and juxtaposed to the belt transverse portion. The head drive includes a wafer carrier for holding a wafer on the distal end portion of the head drive, while a drive moves the distal end portion and a held wafer into a vertical polishing position abutting the belt transverse portion and pressure is applied to the held-wafer against the polishing pad assembly while the wafer-holding distal end portion is rotated and swept side-by-side. After polishing the drive is reversed and the head drive is pivoted away from the belt transverse portion to a horizontal or other orientation and the then polished wafer removed.

Abstract: A process using a retaining ring assembly of a carrier head to precompress a polishing pad to reduce or minimize the edge effect in a chemical mechanical polishing process.
