    摘要: New porous semiconductor dopant carriers are disclosed together with a method for the diffusion doping of semiconductors by the vapor phase transport of an n or p type dopant, such as phosphorus, arsenic, antimony, boron gallium, aluminum, zinc, silicon, tellurium, tin and cadmium to the semiconductor host substrate; wherein the dopant carrier is comprised of a rigid, multiphase dimensionally stable refractory foam, formed through the impregnation, and subsequent thermal destruction of an open-celled organic polymer foam.
