Abstract:
Disclosed are highly scalable fabrication methods for producing electronic circuits, devices, and systems. In one aspect, a fabrication method includes attaching an electronic component at a location on a substrate including a flexible and electrically insulative material; forming a template to encase the electronic component by depositing a material in a phase to conform on the surfaces of the electronic component and the substrate, and causing the material to change to solid form; and producing a circuit or electronic device by forming openings in the substrate to expose conductive portions of the electronic component, creating electrical interconnections coupled to at least some of the conductive portions in a selected arrangement on the substrate, and depositing a layer of an electrically insulative and flexible material over the electrical interconnections on the substrate to form a flexible base of the circuit, in which the produced circuit or electronic device is encased.

Abstract:
A multilayer circuit includes a dielectric base substrate, conductors formed on the base substrate and a vacuum deposited dielectric thin film formed over the conductors and the base substrate. The vacuum deposited dielectric thin film is patterned using sacrificial structures formed by electroplating techniques. Substrates formed in this manner enable significant increases in circuit pattern miniaturization, circuit pattern reliability, interconnect density and significant reduction of over-all substrate thickness.

Abstract:
A system and method for the fabrication of high reliability capacitors (1011), inductors (1012), and multi-layer interconnects (1013) (including resistors (1014)) on various thin film hybrid substrate surfaces (0501) is disclosed. The disclosed method first employs a thin metal layer (0502) deposited and patterned on the substrate (0501). This thin patterned layer (0502) is used to provide both lower electrodes for capacitor structures (0603) and interconnects (0604) between upper electrode components. Next, a dielectric layer (0705) is deposited over the thin patterned layer (0502) and the dielectric layer (0705) is patterned to open contact holes (0806) to the thin patterned layer. The upper electrode layers (0907, 0908, 1009, 1010) are then deposited and patterned on top of the dielectric (0705).
Abstract:
An integrated circuit comprises a substrate (10) consisting of a material having substantially the same thermal-expansion coefficient as that of silicon, metal film (36) formed in a through hole (32) in the substrate (10) and projecting beyond the surface of the substrate, and a feedthrough electrode (38) of solder formed in the through hole (32) with the metal film (36) deposited. A number of such substrates can be laminated to provide a highly integrated reliable circuit board and integrated circuit with such a circuit board.
Abstract:
A resilient electrical connector assembly (100) includes a base PCB and stacked layers of interconnected resilient conductive structures where each structure has at least two resilient conductive strips (115, 130, 145) and at least two conductive contacts (105, 110, 135, 140, 150, 155, 160, 165). One contact is integrated with a conductive path on the base PCB (105, 110) and another contact pad (160, 165) is positioned to establish a conductive path with a target PCB when the latter is mounted parallel to the base PCB. The resilient conductive strips flex due to a compressive force exerted between the base PCB and target PCB on the stacked layers. The resilient conductive structures are formed by depositing metal to sequentially form each of the stacked layers with one contact being initially formed in engagement with the conductive path on the base PCB.
