  • Method and apparatus for fabricating near spherical semiconductor single crystal particulate and the spherical product produced
    Patent number: 6120602
    Abstract: An apparatus and a method for producing single crystal semiconductor particulate in near spherical shape and the particulate product so formed is accomplished by producing uniform, monosized, near spherical droplets; identifying the position of an undercooled droplet in a nucleation zone; and seeding the identified droplet in the nucleation zone to initiate single crystal growth in the droplet.
    Type: Grant
    Filed: December 28, 1999
    Date of Patent: September 19, 2000
    Assignee: Starmet Corporation
    Inventors: Matthew D. Stephens, Steven A. Miller, Jessica Belcher
