Abstract
A manufacturing method of a semiconductor structure includes at least the following steps. Forming a first tier includes forming a conductive via extending from a lower portion of a first interconnect structure into a first semiconductor substrate underlying the lower portion; forming an upper portion of the first interconnect structure on the conductive via and the lower portion; forming a first surface dielectric layer on the upper portion; and forming a first and a second bonding connectors in the first surface dielectric layer. The first bonding connector extends to be in contact with an upper-level interconnecting layer of the first interconnect structure, the second bonding connector is narrower than the first bonding connector and extends to be in contact with a lower-level interconnecting layer of the first interconnect structure, and a top surface of the conductive via is between the upper-level interconnecting layer and the first semiconductor substrate.
