  • Methods for preparing a doped ingot
    Patent number: 11028499
    Abstract: Ingot puller apparatus for preparing silicon ingots that include a dopant feed system are disclosed. The dopant feed system include a dopant conduit having a porous partition member disposed across the dopant conduit. Solid dopant falls onto the partition member where it sublimes. The sublimed dopant is carried by inert gas through the partition member to contact and dope the silicon melt.
    Type: Grant
    Filed: December 14, 2018
    Date of Patent: June 8, 2021
    Assignee: GlobalWafers Co., Ltd.
    Inventors: Roberto Scala, Stephan Haringer, Franco Battan
