Step stress analysis of a metal on silicon (MOS) or polysilicon on silicon (PSOS) product involves a working model for time to fail, approximate knowledge of a voltage parameter Belta, and representative test structures of the product. This method is not applicable where protect diodes cause a limit of the excess field that can be applied unless the firing point of the protect diodes represent fields much greater than will actually be used.
