Abstract:
A method of locating a conductive element on a semiconductor substrate in a desired position, said method comprising:forming said semiconductor substrate having integrated circuitry, having at least one surface and having at least one conductive circuit on a portion of said at least one surface of said semiconductor substrate connected to a portion of said integrated circuitry and terminating in a bond pad, said at least one conductive circuit having a portion thereof covered by at least one first passivation layer without covering said bond pad; forming a conductive trace of solder wettable material from said bond pad of said at least one conductive circuit to a location for another conductive element on said at least one surface of said semiconductor substrate, said conductive trace of said solder wettable material contacting at least a portion of said bond pad of said at least one conductive circuit and extending over a portion of said at least one first passivation layer at said desired position, said conductive trace of said solder wettable material having a first surface and a second surface, a portion of said second surface contacting a portion of said bond pad; forming at least one second passivation layer over said portion of said at least one surface of said semiconductor substrate and said conductive trace; and etching a sloped-wall via through said at least one second passivation layer extending to a portion of said first surface of said conductive trace at said location for said another conductive element located on said at least one surface of said semiconductor substrate.
