    摘要： A method and system for adaptively controlling a laser-based material processing process are provided. The system includes sensing equipment to measure a process variable or condition of at least one of a laser-based material processing system and a workpiece processed by the material processing system and to provide a corresponding measurement signal. The control system also includes a signal processor for processing the measurement signal to obtain a processed signal which initiates, at least semi-automatically, an action associated with at least one of the material processing system and the workpiece. A method and system for at least semi-automatically qualifying a laser-based material processing system which delivers laser energy to locations on or adjacent a plurality of microstructures formed on a workpiece to at least partially process the microstructures are also provided.

    摘要： A laser-based method and system for selectively processing a multi-material device having a target link structure formed on a substrate while avoiding undesirable change to an adjacent link structure also formed on the substrate are disclosed. The method includes applying at least one focused laser pulse having a wavelength into a spot. The at least one focused laser pulse has an energy density over the spot sufficient to completely process the target link structure while avoiding undesirable change to the adjacent link structure, the substrate and any layers between the substrate and the link structures. The target link structure and the adjacent structure may have a pitch of about 2.0 microns or less.
