  • Process for improved doping of semiconductor crystals
    Patent number: 5259916
    Abstract: Doping of IIIB-VB semiconductor crystals grown by the liquid encapsulated Czochralski techniques is improved by introducing a metal to the crucible. The metal is characterized as having a lower melting temperature and a lower free energy of oxide formation than the dopant element.
    Type: Grant
    Filed: April 28, 1992
    Date of Patent: November 9, 1993
    Assignee: Texas Instruments Incorporated
    Inventors: Mann-Fu Rau, Faa-Ching M. Wang, Jimmy D. Kurz
