Abstract
Contacts between polysilicon conductors on the surface of a silicon wafer and doped regions underlying them in the wafer, rendered defective by the growth of a thin intervening oxide layer between conductors and diffusions, are repaired by depositing dots of aluminum on the conductors in the contact areas and annealing the wafer so as to drive traces of the aluminum through the conductors and the intervening oxide into the underlying doped regions in the wafer.
