Abstract:
The present disclosure relates to a package-on-package structure providing mechanical strength and warpage control. In some embodiments, the package-on-package structure includes a first set of conductive elements coupling a first package component to a second package component. A first molding material is arranged on the first package component. The first molding material surrounds the first set of conductive elements and outer sidewalls of the second package component and has a top surface below a top surface of the second package component. The stacked integrated chip structure further includes a second set of conductive elements that couples the second package component to a third package component.

Abstract:
A first protective layer is formed on a first die and a second die, and openings are formed within the first protective layer. The first die and the second die are encapsulated such that the encapsulant is thicker than the first die and the second die, and vias are formed within the openings. A redistribution layer can also be formed to extend over the encapsulant, and the first die may be separated from the second die.

Abstract:
The present disclosure, in some embodiments, relates to a method of forming a package. The method includes coupling a first package component to a second package component using a first set of conductive elements. A first polymer-comprising material is formed over the second package component and surrounding the first set of conductive elements.
