Abstract:
1. A method, comprising: providing a wafer having a first surface and a second surface opposite to the first surface; attaching the first surface of the wafer to a carrier, exposing the second surface of the wafer; thinning the wafer from the second surface, forming a thinned wafer; bonding a plurality of dies onto the thinned wafer, wherein each die of the plurality of dies having a first surface and a second surface, and the first surface of each die is substantially coplanar; encapsulating the thinned wafer and an entirety of surfaces of the dies with a protection layer, the protection layer defining an uncovered region at an edge of the thinned wafer; forming a support structure on the uncovered region at the edge of the thinned wafer, wherein the support structure fills the uncovered region to cover the edge of the thinned wafer; and removing the carrier from the thinned wafer.
