PROBLEM TO BE SOLVED: To provide a means for improving connection reliability by substantially eliminating trouble such as the increase or disconnection, etc., of an electric resistance owing to an electric substance movement in a connection part when using an electronic component (in energization) after mounting on a wiring substrate. SOLUTION: An electronic component (a chip) mounting structure 50 includes: the chip 10 having terminals 11; the wiring substrate 20 having terminals 22P to be electrically connected to the terminals 11 of the chip; and an intervention substrate 30 arranged between the chip 10 and the wiring substrate 20 and having a structure where an insulating base material 31 includes multiple linear conductors 32 penetrating in the thickness direction. The terminals 11 of the chip 10 are electrically connected to the terminals 22P of the wiring substrate 20 via a plurality of linear conductors arranged in the intervention substrate 30.

Abstract:
The present invention provides for a number of interrelated methods for the production of random and ordered arrays of particles as well as films containing the same. In another aspect, the present invention relates to the random and ordered arrays of particles and films prepared therefrom. The ordered arrays are obtained by the use of ferrofluid compositions which may be curable, solidifiable or non-curing/non-solidifiable. Especially preferred arrays and films contain electrically conductive particles for use in electronic applications for effecting contact between leads or pads.

PROBLEM TO BE SOLVED: To provide a conductive film which is used for a connection in which an electronic component having a connection terminal with a narrow pitch is mounted on a wiring board. SOLUTION: The conductive film 10A includes an anodized layer 1 having a plurality of through-holes 2 extending in a thickness direction, a plurality of linear conductors 3 each of which is formed in each of the through-holes 2 and has a projection projecting from the anodized layer 1, and an organic insulating layer 5 which is an uncured thermosetting resin layer that fills spaces between the projections of the linear conductors 3 to be formed on the anodized layer 1. The projections of the linear conductors 3 are coated with a coating agent 4 made of tin or a low melting point alloy containing tin. COPYRIGHT: (C)2011,JPO&INPIT

PROBLEM TO BE SOLVED: To change the capacity easily without the design constraints, to accommodate increase in the capacity, and to facilitate incorporation of a capacitor in a substrate. SOLUTION: The capacitor 10 includes a dielectric substrate 11 and a large number of filamentous conductors 12 formed to penetrate through the dielectric substrate in the thickness direction thereof. An electrode 15a, 16a is connected to only respective one ends of a plurality of filamentous conductors 12 constituting one of groups each composed of a plurality of filamentous conductors. The electrode is disposed in at least one position on each of both surfaces of the dielectric substrate 11, or in at least two positions on one of the surfaces. Further, an insulating layer 13, 14 is formed on each of both surfaces of the dielectric substrate 11 so as to cover regions between the electrodes 15a, 16a, and a conductor layer 15, 16 is formed on the corresponding insulating layer 13, 14 integrally with a desired number of electrodes 15a, 16a.
