Claim Text:
1. A method, comprising: receiving, by a first acousto-optic deflector, a laser beam; diffracting. by the first acousto-optic deflector, the received laser beam along a first axis; receiving, by a second acousto-optic deflector, the diffracted laser beam; diffracting, by the second acousto-optic deflector, the received diffracted laser beam along a second axis, wherein the first acousto-optic deflector and the second acousto-optic deflector are separated by a separation distance in the direction of the diffracted laser beam; and refracting the diffracted laser beam from the second acousto-optic at by magnification optics and directing the diffracted laser beam to a semiconductor substrate to process the semiconductor substrate.
