    Abstract: A method for fabricating a printed circuit board includes the steps of: fabricating a printed circuit board having at least one collapsed portion; depositing a first solder resist in the collapsed portion; exposing the first solder resist-coated printed circuit board at a pressure lower than atmospheric pressure for a predetermined time; coating a second solder resist on the entire surface of the printed circuit board; and drying and hardening the first and the second solder resists. With this method, when a solder resist is coated, since an air space does not remain in a blind via hole, the reliability of the attachment between a printed circuit board and the solder resist layer is increased.

    Abstract: A first signal routing layer may be formed on a first surface of a printed circuit board (PCB). An array of interconnections may formed on the first surface of the PCB, the array of interconnections comprising at least one padless via formed within the PCB, the at least one padless via extending from the first signal routing layer to at least one conductive plane and/or a second signal routing layer. The at least one padless via may be in electrical contact with the at least one conductive plane and/or a conductive trace on the second signal routing layer. A component may be attached to the PCB, with a solder interconnection between the at least one padless via and a contact pad on a bottom surface of the component. The component may be, for example, an electronic component such as a ball grid array (BGA) component or a leadless surface mount component.

    Abstract: A semiconductor device includes: a multi-layered wiring substrate in which a multiple wiring pattern layers are laminated through insulating layers. The multi-layered wiring substrate has a first, semiconductor element mounting face and a second face opposite to the first face. A semiconductor element is mounted on and connected to connecting pads on the first face. A chip-capacitor is arranged on and connected to the connecting pads on the second face. An electric power supply circuit includes the chip-capacitor for supplying electric power to the semiconductor element. Conductor paths for electrically connecting the first connecting pads with the second connecting pads are substantially extended vertically and penetrate through the multi-layered wiring substrate through so as to reduce the length of the conductor paths to a minimum, so that the chip-capacitor is located at the opposite side of the semiconductor element.

    Abstract: The present invention provides a solution to the problem of controlling the inter-layer impedance of a deposited thin film layer stack accommodating high-density interconnects. The invention enables high-density signal lines to be routed over a reference plane to achieve a desired characteristic impedance. In one embodiment, a first thin-film metal layer is formed on a planarized layer fabricated from multiple thin film dielectric layers. The reduced pad footprint in the first thin-film metal layer allows a major portion of the first thin-film metal layer to serve as a reference, or ground, plane to signal lines formed in a second thin-film metal layer that is separated from the first thin-film metal layer by a thin dielectric layer.
