  • Publication number: 20210143032
    Abstract: A substrate processing system includes a processing chamber, a substrate support, a laser, and a collimating assembly. The substrate support is disposed in the processing chamber and is configured to support a substrate. The laser is configured to generate a laser beam. The collimating assembly includes lenses or minors arranged to direct the laser beam at the substrate to heat an exposed material of the substrate. The lenses or mirrors are configured to direct the laser beam in a direction within a predetermined range of being perpendicular to a surface of the substrate.

  • Patent number: 10770297
    Abstract: A method for processing a substrate includes providing a substrate with a layer including a material selected from a group consisting of silicon (Si), germanium (Ge) and silicon germanium. The method includes depositing a first layer on the layer of the substrate using atomic layer deposition (ALD). The method includes depositing a second layer on the first layer using ALD. Depositing one of the first layer and the second layer includes depositing phosphorus oxide and depositing the other one of the first layer and the second layer includes depositing antimony oxide. The method includes annealing the substrate to drive antimony and phosphorus from the first layer and the second layer into the layer of the substrate to create a junction.

  • Patent number: 8323523
    Abstract: A method of bevel edge processing a semiconductor in a bevel plasma processing chamber in which the semiconductor substrate is supported on a semiconductor substrate support is provided. The method comprises evacuating the bevel etcher to a pressure of 3 to 100 Torr and maintaining RF voltage under a threshold value; flowing a process gas into the bevel plasma processing chamber; energizing the process gas into a plasma at a periphery of the semiconductor substrate; and bevel processing the semiconductor substrate with the plasma.
