    Abstract: A communication apparatus including a radio frequency (RF) circuit module can be reduced in the number of components therefor to reduce the cost for its components and to simplify its fabrication process and thus reduce the cost for manufacturing the same while the RF circuit module can also be shielded reliably. The RF circuit module includes a printed circuit board having an upper surface with a circuit component mounted thereto and a lower surface provided with a shielding conductor of metal. The printed circuit board is fit into a shielding frame to assemble the RF circuit module. The RF circuit module is then turned over and thus mounted on that upper surface of a mother board which is provided with conductors of metal. Such conductors of metal and the frame can shield the RF circuit module.

    Abstract: Fundamental interconnect systems for connecting high-speed electronics elements are provided. Interconnect system has the means, which could reduce the microwave loss by reducing the effective dielectric loss and dielectric constant of the interconnect system, and increase the bandwidth of the interconnects, respectively. According to this invention, the interconnection system has also lower effective dielectric constant, which would help to reduce the signal propagation delay and reduce the signal skews. The interconnect systems consists of the signal line, inhomogeneous dielectric system consisting of the homogeneous dielectric layer and conducting or metal plans having 1-diemensioanl or 2-dimensioanl arrays in structure, located into the homogeneous dielectric layer, and the ground plan. The signal line proposed in this invention could be any type of signal line configuration for example, microstripline, strip line or coplanar line. The signal line can also be made as single ended or differential pairs of any configurations. Alternatively, the interconnect systems consists of the signal line, homogeneous dielectric layer, and the ground plan which is in 1-dimensional or 2-dimensional array in structure. The interconnect system based on the fundamental techniques provided in this invention, can be used for on-chip interconnects where the high speed electronics devices are connected by the signal line laid on the oxide or dielectric material. Again, the interconnect system based on the fundamental techniques provided in this invention, can also be used for off-chip interconnects (chip-to-chip interconnects), where the whole portion or portion of the PCB on which high speed chips are to be connected, are having the dielectric system with opened trench or slot to reduce the microwave loss. High scale chip-to-chip interconnection using of the multilayered PCB is possible. The fundamental techniques provided in this invention can also be used for high-speed connectors and high-speed cables. The main advantages of this invention are to make high speed interconnects systems for on-chip and off-chip interconnects. More over, this fundamental technology is also used for the high sped die-package, high speed connector, and high speed cables where conventional manufacturing technology can be used and yet to increase the bandwidth of the interconnects.

    Abstract: Fundamental interconnect systems for connecting high-speed electronics elements are provided. Interconnect system has the means, which could reduce the microwave loss by reducing the effective dielectric loss and dielectric constant of the interconnect system, and increase the bandwidth of the interconnects and also reduce the signal propagation delay, respectively. Ideally, the speed of the electrical signal on the signal line can be reached to speed of the light in the air, and the bandwidth can be reached to closer to the optical fiber. The interconnect systems consists of the signal line, dielectric system with opened trench or slot filled up with the air or lower dielectric loss material, and the ground plan. The signal line proposed in this invention could be made any type of signal line configuration for example, microstripline, strip line or coplanar line. The signal line can also be made as single ended or differential pairs of any configurations. The interconnect system based on the fundamental techniques provided in this invention, can be used for on-chip interconnects where the high speed electronics devices are connected by the signal line laid on the oxide or dielectric material.

    Abstract: An interconnect architecture in which a substrate such as a printed circuit board includes multiple conductive layers separated by one or more interposed insulating layers, the conductive layers being adapted to receive a high density array of interconnect elements such as a ball grid array (BGA). In certain preferred embodiments, a printed circuit board may provide a very low resistance interconnect forming the drain and source terminals of a lateral power MOSFET device incorporating a high density array of alternating source and drain interconnect elements, such as a BGA. In such embodiments, source and drain currents may be routed on different conductive layers separated by one or more interposed insulating layers. The upper conductive layer may include laterally non-conductive regions accommodating conductive columns that are connected to the lower conductive layer.
