Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 14:
15. A method comprising:
depositing a dielectric layer over a workpiece, the dielectric layer encapsulating contact pads disposed over a set of through-silicon vias (TSVs), the set of TSVs partially penetrating a substrate of the workpiece, wherein the dielectric layer laterally surrounds and has an interface with sidewall portions of the contact pads, the contact pads having an upper surface extending into the dielectric layer;
flipping the workpiece over and attaching a first side of the workpiece to a carrier, the workpiece corresponding to a wafer;
thinning the substrate at a second side of the workpiece to expose the set of TSVs, the second side opposite the first side;
following thinning the second side of the workpiece, forming first connectors protruding from the second side of the workpiece;
bonding a first die to the first connectors on the second side of the workpiece, the first die electrically coupled to the set of TSVs;
following bonding the first die to the second side, singulating the workpiece into multiple packages, each package of the multiple packages including the first die;
attaching a second side of a first package of the multiple packages to a carrier, thereby forming a second workpiece;
forming second connectors over a first side of the second workpiece; and
flipping the second workpiece over and attaching the second connectors to a tape.
