Abstract:
A device and method for alignment of a first contact surface of a first substrate with a second contact surface of a second substrate which can be held on a second platform includes first X-Y positions of first alignment keys located along the first contact surface, and second X-Y positions of second alignment keys which correspond to the first alignment keys and which are located along the second contact surface. The first contact surface can be aligned based on the first X-Y positions in the first alignment position and the second contact surface can be aligned based on the second X-Y positions in the second alignment position.
