  • Patent number: 10950472
    Abstract: A ring support is attached to an inner wall surface of a chamber that houses a semiconductor wafer to support a susceptor. When the semiconductor wafer is placed on the susceptor, an inner space of the chamber is separated into an upper space and a lower space. Particles are likely to accumulate on a lower chamber window as a floor part of the chamber. However, since the upper space and the lower space are separated, the semiconductor wafer can be prevented from being contaminated by the particles flowing into the upper space and adhering to a surface of the semiconductor wafer even when the particles on the lower chamber window are blown up by irradiation with flash light.

  • Patent number: 10580620
    Abstract: Embodiments of the present invention provide a plasma chamber design that allows extremely symmetrical electrical, thermal, and gas flow conductance through the chamber. By providing such symmetry, plasma formed within the chamber naturally has improved uniformity across the surface of a substrate disposed in a processing region of the chamber. Further, other chamber additions, such as providing the ability to manipulate the gap between upper and lower electrodes as well as between a gas inlet and a substrate being processed, allows better control of plasma processing and uniformity as compared to conventional systems.

  • Patent number: 10550464
    Abstract: A circular PVD chamber has a plurality of sputtering targets mounted on a top wall of the chamber. A pallet in the chamber is coupled to a motor for rotating the pallet about its center axis. The pallet has a diameter less than the diameter of the circular chamber. The pallet is also shiftable in an XY direction to move the center of the pallet beneath any of the targets so all areas of a workpiece supported by the pallet can be positioned directly below any one of the targets. A scanning magnet is in back of each target and is moved, via a programmed controller, to only be above portions of the workpiece so that no sputtered material is wasted. For depositing a material onto small workpieces, a cooling backside gas volume is created between the pallet and the underside of sticky tape supporting the workpieces.
