Abstract
A method of forming a package comprises assembling at least one chip layer over a carrier substrate, the at least one chip layer including chip couplers and chips, each of the chips having a front side facing the carrier substrate and chip contacts formed on the front side, the couplers including first chip couplers, each of the first chip couplers having an upper side facing away from the carrier substrate and first bumps formed on the upper side. The method further comprises encapsulating the at least one chip layer to form a molded package structure, thinning the molded package structure to expose the first bumps, forming a metal layer on a side of the molded package structure where the first bumps are exposed, removing the carrier to expose another side of the molded package structure, and forming a redistribution layer and second bumps on the molded package structure.
