    摘要: Methods and apparatus for package on package structures. A structure includes a first integrated circuit package including at least one integrated circuit device mounted on a first substrate, a plurality of package on package connectors extending from a bottom surface and arranged in a pattern of one or more rows proximal to an outer periphery of the first substrate; and a second integrated circuit package including at least another integrated circuit device mounted on a second substrate and a plurality of lands on an upper surface coupled to the plurality of package on package connectors, and a plurality of external connectors extending from a bottom surface of the second substrate; wherein the pattern of the external connectors is staggered from the pattern of the package on package connectors so that the package on package connectors are not in vertical alignment with the external connectors. Methods for forming structures are disclosed.

    摘要: A structure includes a metal pad over a semiconductor substrate, a passivation layer having a portion over the metal pad, and a first polyimide layer over the passivation layer, wherein the first polyimide layer has a first thickness and a first Young's modulus. A post-passivation interconnect (PPI) includes a first portion over the first polyimide layer, and a second portion extending into the passivation layer and the first polyimide layer. The PPI is electrically coupled to the metal pad. A second polyimide layer is over the PPI. The second polyimide layer has a second thickness and a second Young's modulus. At least one of a thickness ratio and a Young's modulus ratio is greater than 1.0, wherein the thickness ratio is the ratio of the first thickness to the second thickness, and the Young's modulus ratio is the ratio of the second Young's modulus to the first Young's modulus.
