  • Patent number: 10340144
    Abstract: Disclosed herein is a method for doping a substrate, comprising disposing a coating of a composition comprising a copolymer, a dopant precursor and a solvent on a substrate; where the copolymer is capable of phase segregating and embedding the dopant precursor while in solution; and annealing the substrate at a temperature of 750 to 1300° C. for 0.1 second to 24 hours to diffuse the dopant into the substrate. Disclosed herein too is a semiconductor substrate comprising embedded dopant domains of diameter 3 to 30 nanometers; where the domains comprise Group 13 or Group 15 atoms, wherein the embedded spherical domains are located within 30 nanometers of the substrate surface.
    Type: Grant
    Filed: January 12, 2017
    Date of Patent: July 2, 2019
    Assignees: ROHM AND HAAS ELECTRONIC MATERIALS LLC, DOW GLOBAL TECHNOLOGIES, LLC, THE REGENTS OF THE UNIVERSITY OF CALIFORNIA
    Inventors: Rachel A. Segalman, Peter Trefonas, III, Bhooshan C. Popere, Andrew T. Heitsch
