Abstract

The invention discloses a semiconductor package for internal connection with connecting sheets, comprising: a plurality of chips, each of which has a plurality of top contact areas and bottom contact areas; a plurality of substrates for placing the The chip, the bottom contact area of ​​the chip is electrically connected to the substrate, and the substrate is provided with a plurality of external pins of the substrate; the connecting piece, the connecting piece is connected to a plurality of chips, and is used to connect a plurality of chips correspondingly arranged a plurality of top contact areas, thereby fixing the plurality of chips, and the ends of the connecting sheets are connected to the outside as the pins of the chips; a plastic package is used for packaging chips, substrates, and connecting sheets. The present invention In the process of manufacturing, multiple chips are fixedly connected through one or more connecting pieces, then packaged, and finally the connecting pieces are separated by cutting or grinding on the top of the package. Due to the fixed connection function of the connecting pieces, the present invention avoids the need for chips to be processed in the process. Misalignment during the process affects the circuit performance of the chip.
