Integrated circuit packaging system with stack interconnect and method of manufacture thereof

摘要

A method of manufacture of an integrated circuit packaging system includes: providing a package substrate having a substrate base side and a substrate stack side; mounting an integrated circuit over the substrate stack side; attaching a stack connector to the substrate stack side; forming an encapsulation over the stack connector and the integrated circuit; attaching an external connector to the substrate base side; attaching an adhesive tape to the external connector having spacing between the adhesive tape and the substrate base side; cutting a step portion in the encapsulation to expose the stack connector; cutting a singulation kerf in the package substrate having exit damage on the substrate base side; and removing the adhesive tape.
