Semiconductor device and computer program product for designing the same

Abstract: A semiconductor device has: a plurality of first power supply wires formed in a first wiring layer; a plurality of second power supply wires formed in a second wiring layer; and a plurality of vias connecting between the first wiring layer and the second wiring layer. The plurality of second power supply wires overlap the plurality of first power supply wires at a plurality of intersections. The plurality of vias are arranged regularly at a part of the plurality of intersections.

Mounting assembly of integrated circuit device and method for production thereof

Abstract: A mounting assembly of an integrated circuit device includes an integrated circuit device having pads on its lower side, through holes formed in a mounting substrate at positions opposed to the pads of the integrated circuit device, and solders for connecting the pads of the integrated circuit device with the through holes. An electrode is provided on the inside wall of each through hole, and the mounting substrate includes therein wirings connected to the electrodes. The solder is filled into the through holes to such an extent that the solder filled in the through holes can be visually checked from the lower side of the substrate.

Antenna device and method for attaching the same

Abstract: An antenna device includes: a radio device for radio wave transmission; a primary radiator that has a function to radiates radio waves generated by the radio device; a parabolic reflector that reflects the radio waves radiated from the primary radiator; a shroud that shields against unnecessary radiation radio waves among the radio waves radiated from the primary radiator and reflected by the parabolic reflector; and an antenna mounting mechanism that fits the parabolic reflector to an antenna attachment pole. The shroud is arranged so as to cover at least a right and left of the parabolic reflector, the radio device and the primary radiator are arranged inside the shroud, and the antenna mounting mechanism fits the parabolic reflector to the antenna attachment pole so that the antenna attachment pole is located at a lateral center position of the parabolic reflector.
