A Hall-effect device with a merged and/or non-merged complementary structure in order to cancel stress induced offsets includes an n-type epitaxial Hall element and a p-type Hall element. The p-type Hall element can be implanted directly on top of the n-type epitaxial Hall element. The merged Hall elements can be biased in parallel to provide a zero-bias depletion layer throughout for isolation. The output of the p-type Hall element can be connected to the geometrically corresponding output of the n-type epitaxial Hall element through a suitable resistance. The output signal can be taken at the outputs of the n-type element. The Hall-effect device can be constructed utilizing standard processes.
