    • The present invention provides an electronic device with improved characteristics and a method of making the electronic device. In a method of making an electronic device (piezoelectric device) 74 according to the present invention, an outer edge R1 of a piezoelectric film 52A formed on an electrode film 46A of a laminate 60 is located inside an outer edge R2 of the electrode film 46A. For this reason, in removal of a monocrystalline Si substrate 14 from a multilayer board 61, where an etching solution permeates between polyimide 72 and laminate 60, the etching solution circumvents the electrode film 46A before it reaches the piezoelectric film 52A. Namely, a route A of the etching solution to the piezoelectric film 52A is significantly extended by the electrode film 46A. In the method of making the electronic device 74, therefore, the etching solution is less likely to reach the piezoelectric film 52A. It significantly suppresses a situation of dissolution of the piezoelectric film 52A and realizes improvement in characteristics of the piezoelectric device 74 made.
    • 本发明提供了具有改进特性的电子设备和制造该电子设备的方法。 在制造根据本发明的电子设备(压电器件)74的方法中,形成在层压体60的电极膜46A上的压电膜52A的外边缘R1位于电极膜46A的外边缘R2的内侧 。 因此,从蚀刻液在聚酰亚胺72和层叠体60之间渗透的多层基板61去除单晶Si基板14时,蚀刻液在其到达压电膜52A之前就绕过电极膜46A。 也就是说,通过电极膜46A显着地延长到压电膜52A的蚀刻溶液的路线A. 因此,在制造电子设备74的方法中,蚀刻溶液不太可能到达压电膜52A。 这显着地抑制了压电膜52A的溶解情况,并且实现了所制作的压电装置74的特性的改善。

    • A surface light source device of side light type illuminating an LCD panel and comprising a guide plate, a primary light source, a reflection sheet, and a prism sheet for light control. A plurality of fine light scattering elements and rough area M are formed on an emission face of the guide plate. The rough area M is formed among the light scattering elements and has scattering power weaker than that of the light scattering elements. The dot-like light scattering elements are distributed according to a certain pattern that is designed to promote emission. Emission is promoted where the light scattering elements are formed and also in the area M. Accordingly, fine periodic bright-dark unevenness and glaring are reduced and the prism sheet, disposed on the emission face, is prevented from sticking to the emission face.

    • The invention provides a magneto-resistive effect device of the CPP structure comprising a nonmagnetic intermediate layer, and a first ferromagnetic layer and a second ferromagnetic layer stacked together and formed with the nonmagnetic intermediate layer sandwiched between them. The first ferromagnetic layer and the second ferromagnetic layer are magnetically coupled via the nonmagnetic intermediate layer such that the magnetizations of the first ferromagnetic layer and the second ferromagnetic layer are antiparallel with each other, wherein the mutually antiparallel magnetizations of two magnetic layers lie in a medium opposite plane or front to rear direction and in a rear to front direction. The second ferromagnetic layer is divided by a nonmagnetic intervening layer into a front second ferromagnetic layer and a rear second ferromagnetic layer on the way from the front to the rear, and the front second ferromagnetic layer and a front portion of the first ferromagnetic layer located at a position that makes a pair with the front second ferromagnetic layer via the nonmagnetic intermediate layer defines a substantial magnetic sensor portion with a sense current applied to it in a stacking direction. It is thus possible not only to make use of a structure capable of narrowing the read gap (between the upper and the lower shield) to make improvements in linear recording densities thereby meeting recent demands for ultra-high density recording, but also to get around a problem of unneeded information being written on the medium (media) and make the device less likely to be affected by the magnetic field, thereby enhancing the stability of operation of the device itself as well.
