HALL ELEMENT AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To improve element isolation performance by forming an element isolation film, and facilitate microfabrication by also reducing a level difference on a substrate.SOLUTION: In a hall element, relative misalignment between a well region and a contact region is eliminated. The hall element includes: a plurality of element isolation films 27 provided on a P-type substrate 21 at intervals; an N-type contact region 28 provided between the element isolation films 27 and in the P-type substrate; an interlayer insulation film 30 provided on the element isolation films 27; and wiring 32 provided on the N-type contact region 28 and in a contact hole provided in the interlayer insulation film 30.
