Doping your wafer

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



Comparison of different doping processed

Phosphorous predep Boron predep PECVD doped thin film Doped Poly Si
Generel description Dopants introduced by diffusion from gas-phase (POCL) Dopants introduced by diffusion from solid source wafers Deposition of doped thin film (oxides or nitrides) Dopants introduced by in-situ doping of poly/amorphous Si

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
