measurement tip the conductor tracks are widened to form electrodes the chip is constructed as a platform chip whose electrodes 1 to 8 are provided for a coating array whose coatings connect the electrodes 1 to 8 to the counter electrode 0 the electrode 9 is provided for the arrangement of a temperature sensitive thin film chip whose circuit is likewise closed by the counter electrode 0 the pattern of electrodes conductor tracks and pads is generated by structuring a metallic thin film or by screen printing of a metal paste fig3 shows the heat distribution on the electrode side of the chip at 640 u00b0 c the electrodes are here arranged on the chip in such a way that the electrode surfaces have the smallest possible temperature difference on the back side the chip has a heat conductor in the region of the measurement tip the heat conductor is constructed for a uniform heating of the chip according to fig4 the heat conductor is constructed as a ceramic chip particularly with a conductor track deposited using thin film technology or on the back side as a conductor track 12 on the ceramic strip and covered with a passivation layer 13 the heat conductor 12 is connected electrically by contact pads 14 on the heating plate made of the ceramic strip 11 with a heater a metal layer 15 is deposited and structured to form the pattern according to fig1 to 3 a preferred embodiment is represented by a combined part on a heating plate having a heat conductor on the back side.
