| 摘要 |
Semiconductor packages that contain multiple stacked chips and methods for making such semiconductor packages are described. The packages also contain multiple chips that are stacked vertically. The chips are connected through stud bumps, printed interconnect structures, and conductive pillars formed with the package. The packages also contain two different moldings layers that together operate as an encapsulation material. The semiconductor packages contain a full land pad array at both the bottom and the top of the package, allowing the packages to be used in a package-on-package configuration. The semiconductor packages therefore have a high input/output capability with a small package footprint, and a flexible routing capability. Other embodiments are also described.
