Abstract
PURPOSE:To make it possible to prevent separation due to ultrasonic wave vibration and the like, by forming a separation preventing film around each electrode so as to have an overhung part to cover the peripheral part of the upper surface of the electrode other than a part, where wire is bonded on the upper surface of the electrode. CONSTITUTION:In a magnetic sensor 20, a semiconductor thin film 21 is bonded to the upper part of a substrate 23 through a bonding layer 22. An electrode 24 is provided at each tip of the thin film 21. A separation preventing film 25 is provided. A flange part 25b is deposited on the upper surface of the bonding layer 22. An overhung part 25a is provided on an upper surface 24a of the electrode 24. Thus the electrode 24 is held on the bonding layer 22 with the film 25 so that the electrode 24 is not floated up. Of the upper surface 24a of the electrode 24, a part 24c, to which a wire is bonded, is not covered with the film 25 but exposed. Since the electrode 24 is mechanically reinforced with the film 25 in this way, the electrode 24 is hard to be vibrated, and separation due to lateral deviation at the junction surface with the semiconductor thin film 21 is not yielded.
