    摘要: A laser-based workpiece processing system includes sensors connected to a sensor controller that converts sensor signals into focused spot motion commands for actuating a beam steering device, such as a two-axis steering mirror. The sensors may include a beam position sensor for correcting errors detected in the optical path, such as thermally-induced beam wandering in response to laser or acousto-optic modulator pointing stability, or optical mount dynamics.

    摘要: Systems and methods automatically modify a laser-based system for processing target specimens such as semiconductor wafers. In one embodiment, the laser-based system detects a trigger associated with a processing model. The processing model corresponds to a set of wafers. In response to the trigger, the system automatically adjusts one or more system parameters based on the processing model. The system then uses the modified system parameters to selectively irradiate structures on or within at least one wafer in the set of wafers. In one embodiment, the trigger includes variations in a thermal state related to a motion stage. In response to the variations in the thermal state, the system operates the motion stage in a series of movements until a thermal equilibrium threshold is reached. The sequence of movements may, for example, simulate movements used to process a particular wafer.
