Abstract:
A low resistance metal is charged into holes formed in a semiconductor substrate to thereby form through electrodes. Post electrodes of a wiring-added post electrode component connected together by a support portion thereof are simultaneously fixed to and electrically connected to connection regions formed on an LSI chip. On the front face side, after resin sealing, the support portion is separated so as to expose front face wiring traces. On the back face side, the semiconductor substrate is grounded so as to expose tip ends of the through electrodes. The front face wiring traces exposed to the front face side and the tip ends of the through electrodes exposed to the back face side are used as wiring for external connection.

Claim (Index 1):
A chip-size double side connection package configured such that a semiconductor chip including a semiconductor substrate on which an LSI region and electrode connection regions are formed is connected to wiring for external connection provided on a first main face and to wiring for external connection provided on a second main face, the first and second main faces being located above and below the semiconductor chip, respectively, the chip-size double side connection package being characterized in that\n a low resistance metal is charged into holes formed in the electrode connection regions at required locations to thereby form through electrodes; a wiring-added post electrode component which includes post electrodes supported by a support portion and front face wiring traces connected to the post electrodes is fixed to and electrically connected to upper surface regions of the through electrodes or the electrode connection regions; on the first main face side, the front face wiring traces, which are exposed as a result of separation of the support portion after charging of resin into a space between the semiconductor chip and the support portion, are used as the wiring for external connection; and on the second main face side, tip ends of the through electrodes exposed as a result of grinding the semiconductor substrate are used as the wiring for external connection.
