Abstract
A method for generating platinum features on the surface of a substrate is disclosed. The method provides an inexpensive means for constructing small platinum features. The method utilizes a photoresist mask to define the platinum features. The problems associated with residue from the deposition of the photoresist mask are overcome by utilizing an etching step which removes any such residue. The etching step also allows the platinum features to be recessed into the substrate surface.
