Claim:
1. A semiconductor device, comprising: a first package component having an upper surface coupled to a lower surface of a second package component by a first set of conductive elements; a first polymer-comprising material arranged between the first package component and the second package component and surrounding the first set of conductive elements and the second package component; a third package component coupled to the second package component by a second set of conductive elements; an underfill arranged on the second package component and surrounding the second set of conductive elements, wherein the first polymer-comprising material extends past sidewalls of the underfill; and a second polymer-comprising material surrounding the underfill and the third package component, wherein the second polymer-comprising material contacts upper surfaces of the first polymer-comprising material and the second package component, wherein the upper surfaces of the first polymer-comprising material and the second package component face a same direction as the upper surface of the first package component.
