A method for the transfer of components from a sender substrate to a receiver substrate includes provision and/or production of the components on the sender substrate, transfer of the components of the sender substrate to the transfer substrate, and transfer of the components from the transfer substrate to the receiver substrate. The components can be transferred selectively by means of bonding means and/or debonding means.

An apparatus includes a bottom stage configured to hold a bottom surface of a substrate stack including at least two substrates, a top stage configured to hold a top surface of the substrate stack, and at least one blade configured to be inserted between two adjacent substrates of the substrate stack, wherein the at least one blade has a pointed tip in plan view and has a channel configured to inject air or fluid.

A semiconductor manufacturing method is disclosed. The method includes: providing a first wafer and a second wafer, wherein the first wafer and the second wafer are bonded together; submerging the bonded first and second wafers in an ultrasonic transmitting medium; producing ultrasonic waves; and directing the ultrasonic waves to the bonded first and second wafers through the ultrasonic transmitting medium for a predetermined time period. An associated semiconductor manufacturing system for at least weakening a bonding strength of bonded wafers is also disclosed.

Bonded structures and method of forming the same are provided. A conductive layer is formed on a first surface of a bonded structure, the bonded structure including a first substrate bonded to a second substrate, the first surface of the bonded structure being an exposed surface of the first substrate. A patterned mask having first openings and second openings is formed on the conductive layer, the first openings and the second openings exposing portions of the conductive layer. First portions of first bonding connectors are formed in the first openings and first portions of second bonding connectors are formed in the second openings. The conductive layer is patterned to form second portions of the first bonding connectors and second portions of the second bonding connectors. The bonded structure is bonded to a third substrate using the first bonding connectors and the second bonding connectors.
