Abstract: One semiconductor device includes a wiring substrate, a semiconductor chip, and a sealing body. The wiring substrate includes an insulating base material, a first conductive pattern formed on one surface of the insulating base material, and a second conductive pattern formed on one surface of the insulating base material, connected to the first conductive pattern and having an end face exposed to the side. The semiconductor chip is mounted on the wiring substrate so as to overlap with the first conductive pattern. The sealing body is formed on the wiring substrate so as to cover the semiconductor chip.

Abstract: A universal silicon interposer system and method to enabling the selective use of multiple proprietary microelectronic devices without the need to substantially alter the end-use application(s). The system may be used in the implementation of three-dimensional (stacked) microelectronics having proprietary contact pin patterns.

Abstract: A multi-layer printed wiring board includes a first insulating layer, a second insulating layer having a dissipation factor higher than a dissipation factor of the first insulating layer, a first conductive layer, and a first via connected to a lead wire in the first conductive layer. The first via includes a stub extending through the second insulating layer.

Abstract: A structure of fixing a printed circuit board includes a mold frame coupled with a display panel, a printed circuit board positioned at a rear surface of the display panel and electrically connected to a pad portion of the display panel, and an insulating film covering an outer surface of the printed circuit board.
