Chip-on-chip connection with second chip located in rectangular open window hole in printed circuit board

摘要

A chip package for semiconductor chips is provided by the method of forming a chip package includes the steps of forming a printed circuit board with a window therethrough; forming semiconductor chip connections of one or more primary chips which overlie the window to the printed circuit board by solder connections, locating a suspended semiconductor chip within the window, and connecting the suspended semiconductor chip to one or more primary chips overlying the window in a chip-on-chip connection. A bypass capacitor is formed on the printed circuit board.
