Abstract: The stitch points of segments formed into a workpiece by laser scribing can be improved by controlling aspects such as the velocity of the scanner and the switching points of the laser, such as to allow for lead-in, lead-out, and overlap periods. The locations of the stitch points also can be selected to coincide with existing lines such that the existing lines will function to connect the segments in the event of an offset.

Abstract: Laser-scribing systems and translation stages operable to support a workpiece during laser scribing are provided. A laser-scribing system includes a base section, a bed supported by the base section, a laser, a first driving mechanism operable to move a workpiece longitudinally along the bed, and a second driving mechanism. The bed comprises a movable section configured to translate with respect to the base section. The movable section comprises a gap to allow a laser beam to pass through. The laser is positioned to direct the laser beam through the gap. The second driving mechanism is operable to laterally translate the laser and the movable section in order to scribe a pattern on the workpiece.

Abstract: Laser scribing can be performed on a workpiece (104) such as substrates with layers formed thereon for use in a solar panel without need to rotate the workpiece (104) during the scribing process. A series of lasers (602, 622) can be used to concurrently remove material from multiple positions on the workpiece (104). Each laser (602, 622) can have at least one scanning device (614, 630, 632) positioned along a beam path thereof in order to adjust a position of the laser output relative to the workpiece (104). By adjusting the beam or pulse positions using the scanning devices (614, 630, 632) while translating the workpiece (104), substantially any pattern can be scribed into at least one layer of the workpiece (104) without the need for any rotation of the workpiece (104).
