| Summary: | A process for the production of electrical circuits which include resistors (
1
) contacted by noble metals and electrically connected by way of conductor tracks of copper, and possibly dielectrics, wherein at least the contacts (
2
) of the resistors of noble metal and the adjoining conductor tracks (
4
) of copper are produced by applying pastes and sintering thereof, and wherein the operation of sintering the conductor tracks of copper is effected at temperatures below 850° C. and below the temperature at which copper forms a eutectic with the noble metal, in a nitrogen atmosphere, and there is an electrically conductive separating layer (
5
) between noble metal contacts (
2
) and conductor track (
4
). |
