Abstract:
1. A method of manufacturing a workpiece comprising: forming a dielectric layer over a doped region of a workpiece wherein said doped region comprises a plurality of n-type regions and a plurality of p-type regions; performing a patterned implant into said dielectric layer whereby a plurality of implanted regions are formed, wherein said patterned implant comprises implanting an n-type dopant and a p-type dopant whereby said n-type dopant is implanted through said dielectric layer into said plurality of n-type regions and said p-type dopant is implanted through said dielectric layer into said plurality of p-type regions; selectively etching said dielectric layer to form a plurality of openings, wherein said doped region of said workpiece is exposed through said plurality of said openings; and applying a metal layer to said doped region through said openings.
