Abstract:
A semiconductor device with a first (101) and a second (111) semiconductor chip assembled on an insulating flexible interposer (120). The interposer, preferably about 25 to 50 μm thick, has conductive traces (121), a central planar rectangular area and on each side of the rectangle a wing bent at an angle from the central plane. The central area has metal studs (122, 123) on the top and the bottom surface, which match the terminals of the chips, further conductive vias of a pitch center-to-center about 50 μm or less. The side wings have contact pads (130) with metallic connectors (131) on the bottom surface; the connectors may be solder balls, metal studs, or anisotropic conductive films. The second chip is adhesively attached to a substrate, whereby the interposer faces away from the substrate. The interposer side wings have a convex bending (150) downwardly along the second chip and a concave bending (151) over the substrate; the side wing connectors are attached to the matching substrate sites.
Abstract:
An integrated method of prototyping and manufacturing electronic circuit boards where a new circuit design can move between virtual, prototype, partially merged and fully merged forms in a relatively automated fashion. A scaleable high density matrix of solderless electrical connections between the pin-outs of a plurality of electronic modules forms a virtual breadboard prototype circuit that can be merged into printed circuit board electrical layers to thus directly synthesize manufacturable forms of prototyped electronic circuits.

Abstract:
An electronic device includes a die, a first circuit substrate connected to the die, and a second circuit substrate closely coupled to the first circuit substrate. The die is located between the first and second circuit substrates and is protected from tampering by the close coupling of the first and second circuit substrates. The circuit substrates may be circuit carrying elements (e.g. circuit boards) or may be additional die, may be any number of other substrates, and/or may be a combination of substrates. The device may include a cavity such that the die is located in the cavity. The cavity could be formed by any number of means. The device may also include a second die connected to the second substrate such that the first die and second die are located in proximity to each other on opposite sides of the cavity.

Abstract:
A touch sensor device is provided that uses a flexible circuit substrate to provide an improved input device. Specifically, the present invention uses a touch sensor controller affixed to the flexible circuit substrate, which is coupled to a sensor component to provide a flexible, reliable and cost effective touch sensor suitable for a wide variety of applications. In one embodiment the touch sensor uses a flexible circuit substrate that provides relatively high temperature resistance. This allows the touch sensor controller to be affixed using reliable techniques, such as various types of soldering. The sensor component can comprise a relatively low-temperature-resistant substrate that can provide a cost effective solution. Taken together, this embodiment of the touch sensor provides reliability and flexibility at relatively low cost.

A flexible wiring member which connects a device and an external signal source has a plurality of wire members in which a plurality of wires are formed on one surface of a substrate, and a plurality of wire members is stacked to face the device. A plurality of bumps for connecting with the device are provided to the wires on a surface, of the wirings, facing the device. Bumps of one of the wire members overlapping with the other of the wire members face the device via the through hole formed in the other of the wire members. Accordingly, it is possible to realize high densification of wires in the flexible wiring while suppressing a rise in a cost.
