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-up 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-up 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.
Claims14
A method for making a multi-package module, comprising:
- providing a die-up 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, wherein providing a die-up flip chip first package comprises testing die-up flip chip packages for a performance and reliability requirement, and selecting a package meeting the said requirement as a said first package.
