Apparatus and Method for Laser Heating and Ion Implantation

摘要

An apparatus and method for performing ion implantation while minimizing and/or repairing amorphization of the substrate material. The process comprises exposing a substrate to an ion beam and either concurrently or promptly following the ion implantation using a laser to anneal the surface. In addition, a laser may be utilized to preheat the substrate prior to ion implantation. The laser heats the substrate to a temperature that does not cause the resist layer to be damaged. By utilizing a laser to heat the substrate from the top surface the resist is not damaged allowing for the use of photo resist material.
