Abstract:
A device includes a first package component, and a second package component underlying, and bonded to, the first package component. A molding material is disposed under the first package component and molded to the first and the second package components, wherein the molding material and the first package component form an interface. An isolation region includes a first edge, wherein the first edge of the isolation region contacts a first edge of the first package component and a first edge of the molding material. The isolation has a bottom lower than the interface.
