Abstract:
A foldable substrate is provided that includes a first substrate portion with a first upper surface and a second substrate portion with a second upper surface. A foldable bridge portion couples the first substrate portion to the second substrate portion. The foldable bridge portion includes a coupling strip that extends from the first substrate portion to the second substrate portion with a gap corresponding to a portion of the coupling strip where the gap is defined between the first and second substrate portions by removing portions of a starting wafer substrate. The first and second portions, in one embodiment, include magnetic field sensors and the foldable bridge portion can be bent to arrange the two portions at a predetermined angle to one another. Once bent, the sensor package can be incorporated into a magnetic field sensor assembly to be integrated with other control circuitry.
