  • Patent number: 9378982
    Abstract: Various embodiments of mechanisms for forming through package vias (TPVs) with openings surrounding end-portions of the TPVs and a package on package (PoP) device with bonding structures utilizing the TPVs are provided. The openings are formed by removing materials, such as by laser drill, surrounding the end-portions of the TPVs. The openings surrounding the end-portions of the TPVs of the die package enable solders of the bonding structures formed between another die package to remain in the openings without sliding and consequently increases yield and reliability of the bonding structures. Polymers may also be added to fill the openings surrounding the TPVs or even the space between the die packages to reduce cracking of the bonding structures under stress.
