Abstract
A semiconductor multi-package module having stacked second and first packages, each package including a die attached to a substrate, in which the first and second package substrates are interconnected by wire bonding, and in which the first package is a flip chip ball grid array package in a die-down configuration. Also, a method for making a semiconductor multi-package module, by providing a first package including a first package substrate and having a die-down flip chip configuration, affixing a second package including a second package substrate an upper surface of the first package, and forming z-interconnects between the first and second package substrates.

A multi-package module comprising stacked first and second packages, each said package including a die attached to a substrate, wherein the first and second substrates are interconnected by wire bonding, and wherein the first package comprises a flip-chip ball grid array package having a flip-chip in a die-down configuration.
A method for making a multi-package module, comprising
- providing a die-down flip chip first package including a first package substrate,
- providing a second package including a die and a second package substrate,
- stacking the second package over the first package, and
- electrically interconnecting the first and second packages by wire bonds connecting the first package substrate and the second package substrate.
