    Abstract: The invention offers a board-connecting structure that can provide electrodes with a fine pitch and that can combine the insulating property and the connection reliability. The structure of connecting printed wiring boards 10 and 20 electrically connects a plurality of first electrodes 12 and 13 provided to be adjacent to each other on a first board 11 with a plurality of second electrodes 22 and 23 provided to be adjacent to each other on a second board 21 through an adhesive 30 that contains conductive particles 31 and that has anisotropic conductivity. By heating and pressing the adhesive placed between the mutually facing first electrode 12 and second electrode 22 and between the mutually facing first electrode 13 and second electrode 23, an adhesive layer 30a is formed between the first board 11 and the second board 21 and in the adhesive layer 30a, a cavity portion 33 is formed between the first electrodes 12 and 13 and between the second electrodes 22 and 23.

    Abstract: A circuit board or microelectronic device in which conductive signal lines are suspended or supported by filaments in air, rather than surrounded by a solid dielectric material. Dry air has a low relative permittivity and extremely low loss tangent compared with common dielectric substrates in which signal lines are currently embedded within circuit boards and microelectronic devices. The signal intensity attenuation for filament-suspended or filament-supported signal lines is much lower than signal lines embedded in solid dielectric materials, allowing for transmission of significantly higher frequency signals within filament-suspended and filament-supported signal lines.

    Abstract: An electronic structure including a metallic interlocking structure for bonding a conductive plated layer to metal surface, and a method of forming the electronic structure. The method provides a substrate having a metallic sheet within a dielectric layer. The metallic sheet includes a metal such as copper. An opening in the substrate, such as a blind via, is formed by laser drilling through the dielectric layer and partially through the metallic sheet. If the opening is a blind via, then the laser drilling is within an outer ring of the blind via cross section using a laser beam having a target diameter between about 20% and about 150% of a radius of the blind via cross section. A surface at the bottom of the opening, called a nullblind surface,null includes a metallic protrusion formed by the laser drilling, such that the metallic protrusion is integral with a portion of the blind surface. The metallic protrusion includes the metal of the metallic sheet and at least one constituent element from the dielectric layer. The metallic protrusion is then etched to form a metallic interlocking structure that is integral with the portion of the blind surface. The metallic interlocking structure includes discrete metallic fibers, with each metallic fiber having a curved (or curled) geometry. Each metallic fiber has its own unique composition that includes the metal, at least one constituent element of the dielectric layer, or both.
