    Abstract: A package-on-package stacked microelectronic structure comprising a pair of microelectronic packages attached to one another in a flipped configuration. In one embodiment, the package-on-package stacked microelectronic structure may comprise a first and a second microelectronic package, each comprising a substrate having at least one package connection bond pad formed on a first surface of each microelectronic package substrate, and each having at least one microelectronic device electrically connected to the each microelectronic package substrate first surface, wherein the first and the second microelectronic package are connected to one another with at least one package-to-package interconnection structure extending between the first microelectronic package connection bond pad and the second microelectronic package connection bond pad.

    Abstract: Semiconductor packages and methods, systems, and apparatuses of forming such packages are described. A method of forming a semiconductor package may include encapsulating a semiconductor die with a molding compound, applying a seed layer on the die and the molding compound, applying a resist layer on the seed layer, exposing a first portion of the resist layer, and exposing a second portion of the resist layer. The first portion can include a first area of the resist layer to be used for forming a redistribution layer (RDL) without including a second area of the resist layer to be used for forming an electrical communications pathway between at least one of the contact pads and the RDL. The second portion can include the second area of the resist layer that includes the electrical communications pathway.
