Title:
電流検出器およびそれを含む半導体装置
Document Type and Number:
Japanese Patent JP5773813
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a current detector in which influence of positional variations between detection-target current lines and a magnetoelectric transducer is suppressed, and a semiconductor device including the same.SOLUTION: Detection-target current lines 13 and 14 are formed by two parallel current lines having the same direction of a current i in the vicinity of a magnetoelectric transducer 1; and the same current i flows through the detection-target current lines 13 and 14. The magnetoelectric transducer 1 is arranged on an upper layer (on a side far from a substrate) through an insulating film with respect to the detection-target current lines 13 and 14. By appropriately setting the spacing between the two detection-target current lines 13 and 14, a magnetic field distribution in the vicinity of the magnetoelectric transducer 1 becomes gradual. Consequently, influence of positional variations between the detection-target current lines 13 and 14 and the magnetoelectric transducer 1 is reduced.
