Abstract
A semiconductor multi-package module has stacked lower and upper packages, each of which includes a die attached to a substrate, in which the second package is inverted, in which the upper and lower substrates are interconnected by wire bonding, and in which the inverted second package comprises a wire bond carrier package. Also, a method for making a semiconductor multi-package module, by providing a lower molded package including a lower substrate and a die, affixing an upper wire bond carrier package including an upper substrate in inverted orientation onto the upper surface of the lower package, and forming z-interconnects between the upper and lower substrates.
