  • Patent number: 10269778
    Abstract: Various embodiments of mechanisms for forming through package vias (TPVs) with multiple conductive layers and/or recesses in a die package and a package on package (PoP) device with bonding structures utilizing the TPVs are provided. One of the multiple conductive layers acts as a protective layer of the main conductive layer of the TPVs. The protective layer is less likely to oxidize and also has a slower formation rate of intermetallic compound (IMC) when exposed to solder. The recesses in TPVs of a die package are filled by solder from the other die package and the IMC layer formed is below the surface of TPVs, which strengthen the bonding structures.
