Doping your wafer

This page is about doping your wafer or making a thin film layer doped with boron, phosphor or Germane.

PECVD - Making boron glass (BSG), phosphorus glass (PSG), boron-phosphorus glass PBSG or germanium doped glass
Furnace LPCVD PolySilicon - Deposition of PolySi doped with B or P
Dope with Boron - Doping Silicon wafers with boron by thermal predeposition and drive-in
Dope with Phosphorus - Doping Silicon wafers with phosphorus by thermal predeposition and drive-in
Ion implantation

Ion implantation cannot be done at Danchip. IBS offers ion-beam implantation as a service. See more at: http://www.ion-beam-services.com/about_us.htm
