Abstract

PURPOSE:To remove the oxide film which hampers the diffusion grown during the diffusion of the previous stage and obtain buried layers of low layer resistance with less variation by performing a deposition process by dividing it in short times of more than twice at the time of performing the diffusion by using a Sb or Sb oxide on Si wafer surface.
