Insane precision from $ASML in this video. Watch from ~1:30 onward "Fun fact: the movement of the reticle stage and wafer stage are synced, but *light speed has to be taken into account*. The reticle stage needs to move slightly earlier, since it can shift more than 100 nanometers in the time between when a photon leaves the reticle and when it reaches the wafer." Sweet video ASML, keep 'em coming.
