Actually this is not stitching, but tiling : pieces of silicon are put together. Stitching is done during the lithographic steps of the wafer production and that is here not the case in the movie. To make things a bit more complicated : most probably stitching is applied to realize the large-area devices and then later they are tiled together to make 40cm x 40cm detectors. The tiling in shown in the movie.
A lot of image sensors / cameras are involved in the production of image sensors. Most of the machines visible in the video use cameras for alignment and inspection tasks
Quite impressive (especially the large stitched sensors), apart from the guy putting on his nitrile gloves AFTER entering the clean room!
