Precision 3D-Integrated Circuit Wafer-to-Wafer Alignment and Bonding

In a system for aligning at least two semiconductor structures for coupling, an alignment device includes a mounting structure having at least first and second opposing portions. The alignment device also includes a first mounting portion movably coupled to the first portion of the mounting structure, the first mounting portion configured to couple to a first surface of a first semiconductor structure. The alignment device additionally includes a second mounting portion movably coupled to the second portion of the mounting structure, the second mounting portion configured to couple to a second surface of a second semiconductor structure. The alignment device further includes one or more imaging devices disposed above at least one of the first and second mounting portions of the alignment device, the imaging devices configured to capture and/or or detect alignment marks in at least the first semiconductor structure. A corresponding method for aligning two or more semiconductor structures for coupling is also provided.
