A package includes a first die, a second die, a first encapsulant, first through insulating vias (TIV), a second encapsulant, and second TIVs. The second die is stacked on the first die. The first encapsulant laterally encapsulates the first die. The first TIVs are aside the first die. The first TIVs penetrate through the first encapsulant and are electrically floating. The second encapsulant laterally encapsulates the second die. The second TIVs are aside the second die. The second TIVs penetrate through the second encapsulant and are electrically floating. The second TIVs are substantially aligned with the first TIVs.

In some aspects, it is disclosed an electrical support for at least one electrical contact pad, including an insulating viscoelastic matrix, and at least one elastically deformable structure made of a conductive material to form an open web, the at least one structure including at least a core part which is embedded within the insulating matrix, and at least one connection part which extends out of the insulating matrix and is configured to be connected to the at least one electrical contact pad, wherein the structure includes a stiffer section corresponding substantially to the core part of the structure and at least one more flexible section corresponding substantially to the at least one connection part of the structure.

A package includes a carrier substrate, a first die, and a second die. The first die includes a first bonding layer, a second bonding layer opposite to the first bonding layer, and an alignment mark embedded in the first bonding layer. The first bonding layer is fusion bonded to the carrier substrate. The second die includes a third bonding layer. The third bonding layer is hybrid bonded to the second bonding layer of the first die.
