  • Publication number: 20240030192
    Abstract: A stack package, and a method of manufacturing the same, includes a first encapsulant layer formed on a carrier. Also semiconductor dies are sequentially offset stacked on the first encapsulant layer. Vertical connectors connected to the semiconductor dies are formed. A second encapsulant layer coupled to the first encapsulant layer is formed to encapsulate the vertical connectors and the semiconductor dies. Redistribution layers connected to the vertical connectors are formed on the second encapsulant layer.
