Abstract
A sensor having a sensor bridge supported above a substrate is disclosed. A number of thermally isolating apertures are provided in the sensor bridge to help increase the thermal isolation of the sensor bridge from the substrate. In one illustrative embodiment, a heater element, an upstream sensor element, and/or a downstream sensor element are provided on the sensor bridge. A plurality of apertures may extend through the sensor bridge to thermally isolate the heater element, the upstream and/or downstream sensor element from the substrate and/or from each other. In one illustrative embodiment, the plurality of apertures may be provided at spaced locations adjacent a first lateral side of the sensor bridge, adjacent the second lateral side of the sensor bridge, between the heater element and the upstream sensor element, and/or between the heater element and the downstream sensor element. In some cases, the plurality of apertures may be substantially round, oval, rectangular and/or any other suitable shape.
