Abstract

A method of forming a package comprises forming a stack of chip layers on a carrier. The stack of chip layers including at least a first chip layer over the carrier and a second chip layer over the first chip layer. The first chip layer includes a plurality of first chips facing the carrier and a plurality of chip couplers. The second chip layer includes a plurality of second chips facing the first chip layer. The method further comprises encapsulating the stack of chip layers in a molding compound, removing the carrier to expose the front side of the first chip layer, forming a redistribution layer on the front side of the first chip layer and bumps on the redistribution layer, and dividing the stack of chips and the redistribution layer to form a plurality of the packages. A chip package thus formed include a stack of chips and one or more chip connectors on a singulated redistribution layer.
