Abstract: With a sensor and method, it is possible for platinum resistor elements to be used advantageously as heating elements, temperature sensors, printed circuit traces, or as chemically resistant electron beam sensitive layers. To ensure a long-lasting adhesion of the platinum resistance layer to a dielectric substrate, even during exposure to temperatures which are elevated over ambient temperature and under dry and most atmospheric conditions, a thin adhesion layer of platinum silicide, for example, is deposited between the platinum resistance layer and the dielectric substrate. Resistor elements patterned from the platinum layer can advantageously be used in temperature sensors, mass flow sensors, chemical sensors, gas sensors, or humidity sensors.
