ABSTRACT:
A method for producing a desired resistive taper under computer control for controlling the surface resistivity of an electrical element, which comprises the steps of creating a computer controlled optically graded pattern corresponding to the desired resistive taper, producing a phototool from the graded pattern and using the phototool to photochemically etch the graded pattern onto a substrate.
