INTEGRATED CIRCUIT PACKAGE-ON-PACKAGE SYSTEM WITH ANTI-MOLD FLASH FEATURE

摘要

An integrated circuit package-on-package system includes: mounting an integrated circuit package system having a mountable substrate over a package substrate with the mountable substrate having a mold structure; forming a package encapsulation having a recess over the package substrate and the integrated circuit package system. The present invention also includes: forming an anti-mold flash feature with an extension portion of the package encapsulation and constrained by the mold structure at the bottom of the recess, and partially exposing the mountable substrate in the recess with the anti-mold flash feature formed with the mold structure; and mounting an integrated circuit device over the mountable substrate in the recess.
