Abstract:
A process for manufacturing a resistor, particularly a measuring resistance for a rapidly responding temperature sensor, having a conductor path provided with at least two connection contact fields which are arranged on an electrically insulating surface of a ceramic substrate, wherein a portion of the conductor path spans a recess in the substrate in a bridge-like manner and the conductor path is arranged in a plane and wherein the conductor path is fastened on the electrically insulating surface of the substrate in an edge area of the substrate adjacent to the recess, the process comprising creating a recess (3) in the substrate (1), filling the recess with a filler selected from the group consisting of glass pastes, glass ceramics, glass solder, silver, indium, nickel, and silver-nickel alloys, levelling the filling thus introduced with an outer surface of the substrate (1), applying the conductor path (4) to the substrate galvanically or in a thin film process as a platinum layer/Pt foil with a thickness in a range of 1 to 6 .mu.m or of a gold layer with a thickness in a range of 1 to 8 .mu.m, subsequently applying a structured cover layer (8) at least partially on the conductor path (4), and thereafter etching away the filler situated in the recess (3).
