Claim 0:
1. A method comprising:
forming a first device, wherein forming the first device comprises:
bonding a first surface of a first die to a substrate;
thinning the substrate to reduce the thickness of the substrate to a first thickness;
bonding a second surface of the first die to a second die; and
after bonding the first surface of the first die to the substrate, and after bonding the second surface of the first die to the second die, planarizing a top surface of the second die;

attaching the first device and a second device to a redistribution structure;
encapsulating the first device and the second device with an encapsulant; and
thinning the encapsulant until a top surface of the encapsulant is coplanar with a top surface of the substrate.
