Multi-chip package having a logic chip disposed in a package substrate opening and connecting to an interposer

摘要

A multi-chip package may include a package substrate, a connecting substrate, a plurality of semiconductor chips and a logic chip. The package substrate may have an opening. The connecting substrate may be arranged on an upper surface of the package substrate. The semiconductor chips may be stacked on an upper surface of the connecting substrate. The semiconductor chips may be electrically connected with the connecting substrate. The logic chip may be arranged in the opening. The logic chip may be electrically connected between the connecting substrate and the package substrate. Thus, the logic chip may not act as to increase a width of the multi-chip package.

主权项

1. A multi-chip package comprising:
a package substrate including an opening therein; an interposer disposed on the package substrate to cover the opening; a stack of semiconductor chips disposed on a first surface of the interposer; a logic chip disposed in the opening and on a second surface of the interposer opposite the first surface; and a first logic pad on a surface of the logic chip and electrically connected to a second pad of the interposer located at the opening, the second pad electrically connected to the stack of semiconductor chips, wherein the logic chip electrically connects to the stack of semiconductor chips through the interposer and also includes direct electrical connections to the package substrate that do not pass through the interposer.
