Abstract:
A semiconductor Hall sensor having a cross-shaped pattern that includes an input side pattern with a length and width of L1 and W1 and a output side pattern with a length and width of L2 and W2, said semiconductor Hall sensor being characterized in that:a film thickness, impurity concentration, the length L1 and width W1 of the input side pattern and length L2 and width W2 of the output side pattern are maintained; and at least one of a resistance across input side terminals and a resistance across output side terminals is made 1.25 to 2.75 times a resistance of a cross-shaped pattern consisting of a rectangle with the length L1 and width W1 serving as the input side pattern, and a rectangle with the length L2 and width W2 serving as the output side pattern.
