  • Hall effect sensor
    Patent number: 6734514
    Abstract: A metrological Hall effect sensor with sensitivity to temperature less than 250 ppm/° C. and with high Hall effect coefficient for temperatures greater than 200° C. formed in a multilayer structure comprising a thin active layer deposited on a substrate, wherein the substrate is made of monocrystalline silicon carbide (SiC), and wherein the thin active layer is made of a weakly type n-doped silicon carbide (SiC) semiconductor in the exhaustion regime.
    Type: Grant
