Semiconductor stacked multi-package module having inverted second package
View Patent ↗A semiconductor multi-package module has stacked lower and upper packages, each package including a die attached to a substrate, in which the upper and lower substrates are interconnected by wire bonding, and in which the upper package is inverted. 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 molded 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.
1. A multi-package module comprising stacked lower and upper packages, each said package including a die attached to a substrate, wherein the substrate comprises a dielectric layer and a pattern patterned metal layer, wherein the upper package is inverted and wherein the upper and lower substrates are interconnected by wire bonding wherein at least one said package is a ball grid array package.
2. The multipackage module of claim 1 wherein at least one said package has wire bond interconnect of the die with the substrate.
3. The multipackage module of claim 1 wherein at least one said package has wire bond interconnect of the die with the substrate, and wherein the said package is fully encapsulated.
4. The multipackage module of claim 1 wherein at least one said package is a land grid array package.
5. The multipackage module of claim 1 wherein at least one said package has flip chip interconnect of the die with the substrate.
6. The multipackage module of claim 1 , further comprising a heat spreader.
7. The multipackage module of claim 1 , further comprising an electromagnetic shield for at least one of the packages.
8. A computer including a multi-package module, comprising the multi-package module having stacked lower and inverted upper packages of claim 1 , said multi-package module being connected to underlying circuitry in the computer.
9. A consumer electronics device including a multi-package module, comprising the multi-package module having stacked lower and inverted upper packages of claim 1 , said multi-package module being connected to underlying circuitry in the consumer electronics device.
10. A portable telecommunications device including a multi-package module, comprising the multi-package module having stacked lower and inverted upper packages of claim 1 , said multi-package module being connected to underlying circuitry in the portable telecommunications device.
11. A multi-package module comprising stacked lower and upper packages, each said package including a die attached to a substrate, wherein the upper package is inverted and wherein the upper and lower substrates are interconnected by wire bonding, comprising a third package stacked over the upper package.
