Abstract
A semiconductor device includes an SIL type package for projection of the pellet of a Hall sensor used for detecting the position of a motor. An inclined portion is formed on an edge portion which faces the motor coil so that the edge portion will come into area-contact with the motor coil even if they come into contact with each other, thus causing no stress concentration on the motor coil.
