Damage free enhancement of dopant diffusion into a substrate
A method of doping a substrate. The method may include implanting a dose of a helium species into the substrate through a surface of the substrate at an implant temperature of 300° C. or greater. The method may further include depositing a doping layer containing a dopant on the surface of the subst...

| Zusammenfassung: | A method of doping a substrate. The method may include implanting a dose of a helium species into the substrate through a surface of the substrate at an implant temperature of 300° C. or greater. The method may further include depositing a doping layer containing a dopant on the surface of the substrate, and annealing the substrate at an anneal temperature, the anneal temperature being greater than the implant temperature. |
