ABSTRACT:
Magnetosensitive semiconductor devices are produced by forming a magnetosensitive part on one surface of a semiconductor substrate, pasting the semiconductor substrate thus formed on a jig, wrapping or etching the opposite surface of the semiconductor substrate, pasting a magnetic substrate on it with the jig pasted thereon, dividing the pasted substrates into individual unistructural elements each with a semiconductor chip and a magnetic piece, and die bonding, wire bonding and resin molding these individual elements.
