Patent ID: 8071451

Claim:
A method of doping a semiconductor body, comprising: exposing the semiconductor body to an activated hydrogen gas for a predetermined time, wherein the activated hydrogen gas reacts with one or more surfaces of the semiconductor body to form a reactive layer comprised within the one or more surfaces, and wherein the semiconductor body comprises a silicon, germanium, or silicon-germanium substrate, wherein the reactive layer comprises dangling bonds comprising one or more of: dangling silicon bonds, silicon hydrogen (Siâ€”H) bonds, silanol (Siâ€”OH) bonds, germanium hydrogen (Geâ€”H) bonds, and germanol (Geâ€”OH) bonds; exposing the semiconductor body to an ultraviolet illumination source or a plasma after exposing the semiconductor body to the activated hydrogen gas, wherein the ultraviolet illumination source or the plasma are configured to change a density of one or more of Siâ€”H, Siâ€”OH, Geâ€”H, and Geâ€”OH bonds; and exposing the semiconductor body to a reactant comprising an n-type or p-type dopant species, wherein the reactant is configured to chemically react with the dangling bonds within the reactive layer to form a doped layer.
