    Abstract: PROBLEM TO BE SOLVED: To provide a wiring substrate capable of preventing deformation such as a warpage or the like, or substantially reducing the amount of deformation; to provide its manufacturing method; and to prevent conveyance failure and mounting failure caused by deformation of the wiring substrate in an electronic mounting process. SOLUTION: In the wiring board, one or more layers having a coefficient of thermal expansion different from that of a core layer are laminated on at least one surface side of the core layer, and a plurality of mounting regions to which a plurality of electronic components are mounted are formed on the surface layers of the laminated layers with prescribed spaces left between them. The core layer is divided for each mounting region or correspondingly to a group of the mounting regions covering a plurality of the mounting regions, and an insulating material forming the laminated layers is filled in a gap between the mutually adjoining core layers.

    Abstract: PROBLEM TO BE SOLVED: To provide a thin-film capacitor in which V BD can be raised while suppressing variation in capacity and thereby the device characteristics and the reliability of product can be enhanced. SOLUTION: Each electronic component 1-4 has a capacitor 11 formed on a smooth substrate 51 having a planarization layer 52 formed on the surface as a base material. The capacitor 11 has such a structure as a lower conductor 21 consisting of an underlying conductor 21a and a conductor 21b, a dielectric film 31 composed of alumina, a resin layer J1 principally composed of novolak based resin, a resin layer J2 principally composed of polyimide based resin, and an upper conductor 25 consisting of an underlying conductor 25a and a conductor 25b are formed on the planarization layer 52 of the substrate 51. The resin layer J1 has an opening K1 above the lower conductor 21 and the resin layer J2 has an opening K2 larger than the opening K1. COPYRIGHT: (C)2008,JPO&INPIT
