Abstract:
Various embodiments of the present application are directed towards a method for workpiece-level alignment with low alignment error and high throughput. In some embodiments, the method comprises aligning a first alignment mark on a first workpiece to a field of view (FOV) of an imaging device based on feedback from the imaging device, and further aligning a second alignment mark on a second workpiece to the first alignment mark based on feedback from the imaging device. The second workpiece is outside the FOV during the aligning of the first alignment mark. The aligning of the second alignment mark is performed without moving the first alignment mark out of the FOV. Further, the imaging device views the second alignment mark, and further views the first alignment mark through the second workpiece, during the aligning of the second alignment mark. The imaging device may, for example, perform imaging with reflected infrared radiation.

Claim (Index 3):
The method according to  claim 1 , wherein the first workpiece is on an upper side of a first workpiece stage, wherein the second workpiece is on an under side of a second workpiece stage, and wherein the aligning of the second alignment mark comprises controlling the second workpiece stage to laterally move the second alignment mark into alignment with the first alignment mark.
