Claim:
1. A method, comprising: placing a first die and a second die on a substrate, a height of the first die being different than a height of the second die, wherein the height of the first die is a shortest distance from a surface of the substrate to a furthermost surface of the first die from the substrate and the height of the second die is a shortest distance from the surface of the substrate to a furthermost surface of the second die from the substrate; forming a molding compound along sidewalls of the first die and the second die, wherein a top surface of the first die and a top surface of the second die is covered by a film layer while the molding compound is formed; laminating a polymer layer over the first die and the second die, wherein the polymer layer extends laterally past edge portions of the first die and the second die; forming a first conductive via in the polymer layer, wherein the first conductive via is electrically connected to a contact pad at a top surface of the first die; and forming a second conductive via in the polymer layer, wherein the second conductive via is electrically connected to a contact pad at a top surface of the second die.
