Abstract
A method includes coating a release film over a carrier. The carrier includes a first material having a first Coefficient of Thermal Expansion (CTE), and a second material having a second CTE different from the first CTE. The method further includes placing a device die over the release film, encapsulating the device die in an encapsulant, and planarizing the encapsulant until the device die is revealed.
