    Abstract: First to fourth power wiring conductors and first to fourth ground wiring conductors are arranged on first to fourth insulating layers, respectively, and a first signal wiring conductor is arranged on the first or second insulating layer and a second signal wiring conductor is arranged on the third or fourth insulating layer. In a multilayer circuit board of the invention, the first to fourth insulating layers are sequentially overlaid in the following manner: each of wiring conductors on the same insulating layer is arranged substantially in parallel to each other, each set of the first power wiring conductor and the second ground wiring conductor, the first ground wiring conductor and the second power wiring conductor, the third power wiring conductor and the fourth ground wiring conductor, and the third ground wiring conductor and the fourth power wiring conductor is arranged so that two wiring conductors are opposed to each other nearly in parallel while interposing the insulating layer therebetween, and each wiring on the first and second insulating layers and each wiring on the third and fourth insulating layers intersect at a right angle, and wherein the first to fourth power wiring conductors and the first to fourth ground wiring conductors are connected via thorough conductors disposed through the insulating layers. The inventive multilayer circuit board ensures a uniform characteristic impedance on the signal wiring conductor to enable a stable power supply to a semiconductor device.

    Abstract: A capacitor with low equivalent series inductance includes multiple electrode layers arranged in parallel with alternating ones of the electrode layers connected together to form the two electrodes of the capacitor. A first set of the electrode layers are connected by an outer wall. A second set of the electrode layers are connected by a central post. Terminals on the capacitor can be spaced on a surface so that signals can be conveniently routed when the capacitor is mounted on or in a printed circuit board or integrated circuit package. Terminals can be included on opposing surfaces of the capacitors to provide for stacking. Additionally, one of the terminals substantially surrounds the other terminal and can provide electromagnetic shielding.

    Abstract: A multilayer wiring board includes a signal electrode, a first power supply electrode, and a ground electrode, which are connected to a first element that outputs a signal, an electrode connected to a second element that receives the signal, a ground layer that serves as a return path for a return current of the signal, a first power supply layer that is disposed adjacent to the ground layer with a dielectric layer interposed therebetween and supplies electric power to the first element, and a second power supply layer that is provided independently of the first power supply layer and supplies electric power to the second element. The first power supply layer causes the return current to return to the first element through the first power supply electrode as a displacement current between the ground layer and the first power supply layer.
