DOPING OF A SUBSTRATE VIA A DOPANT CONTAINING POLYMER FILM

摘要

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.
