Abstract:
The invention shows a doping method that can be used for doping of wafers. The method comprises making at least one ensemble of pores into a wafer matrix to be doped, depositing a vehicle layer on the substrate area of at least one said ensemble of pores and/or their walls, to form a vehicle layer as an interfacing surface for the dopant passage by diffusion. The deposition is followed by annealing said wafer in annealing specific conditions for enhancement of diffusion of said dopant from said vehicle layer via said interfacing surface into the wafer matrix to be doped. After the diffusion enhancement by annealing, the method comprises washing the vehicle layer away, by a washing agent for removal of the deposited dopant comprising material from the wafer surface and the pores. The doped porous structure of the wafer matrix comprising the dopant is then recrystallized, in a recrystallizing environment defined by recrystallizing parameters. The surface is finished and polished.
