Abstract:
1. A method of treating a substrate, comprising: implanting octadecaborane into the surface of the substrate; melting the implanted surface of the substrate; resolidifying the surface of the substrate; annealing the surface of the substrate; and oxidizing the surface of the substrate, wherein the octadecaborane is implanted by directing octadecaborane ions having average energy less than about 1 keV toward the substrate, melting the substrate comprises directing laser energy toward a portion of the substrate and maintaining a temperature of the portion of the substrate above about 1,100° C. for a duration less than about 0.5 sec, resolidifying the substrate comprises cooling the melted portion of the substrate at a controlled rate, and annealing the substrate comprises maintaining a temperature of the portion of the substrate at about 400° C. or higher for at least about 1 minute.
