Abstract
The present invention provides a thin magnetoelectric transducer which has a projected size substantially equal to that of a pellet and which can be subjected to an inspection test nondestructively. The magnetoelectric transducer has a semiconductor device provided on the upper surface of a projecting portion of a projecting nonmagnetic insulating substrate 9 and comprising a magnetosensitive section 3 and inner electrodes 2 made of metal. A conductive resin layer 4 is formed on the internal electrodes 2 and on part of the side surfaces of the projecting portion. A strain buffering layer 5 is formed at least on the magnetosensitive section 3. Furthermore, at least the strain buffering layer 5 on the magnetosensitive section 3 is coated with a protective layer 6.
Claims9
A magnetoelectric transducer characterized in that the transducer comprises a magnetosensitive section and internal electrodes formed on an upper surface of insulating substrate having conductive layers formed on side surfaces thereof, that an insulating portion and each of said conductive layers are formed of a sintered compact, that the sintered compact of said conductive layer is mainly included of metal of a high melting point of 1,600° C. or higher and ceramic powders, and that the sintered compact of said conductive layer contains 10% to 90% of the high-melting point metal.
