| 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 source comprises a dopant containing porous, inert, rigid dimensionally stable and thermal shock resistant carrier comprised of SiC, elemental silicon or mixtures thereof. |
