Abstract: A polysilicon deposition process is disclosed for forming a doped polysilicon layer over a stepped surface on a semiconductor wafer having the deposition characteristics and resulting profile of an undoped polysilicon layer which comprises: depositing doped polysilicon on the stepped surface, depositing undoped polysilicon over the doped polysilicon, repeating the doped and undoped depositions cyclically until the desired amount of polysilicon has been deposited, and then annealing the deposited polysilicon to uniformly distribute the dopant throughout the entire deposited polysilicon layer.
