    Abstract: PROBLEM TO BE SOLVED: To solve following problems: in removal processing using a pulsed laser beam, processing deviation occurs in the depthwise direction to cause a processing error in a predetermined removal shape.SOLUTION: A pulsed laser beam L1 is a pulsed laser beam having a wavelength that exhibits transmittance to a workpiece 6, and a pulsed laser beam L2 is a pulsed laser beam having a wavelength that exhibits absorption to the workpiece 6. The pulsed laser beam L1 is focused into the workpiece 6, and a focal point P1 of the pulsed laser beam L1 is scanned along the outline of a predetermined removal region R1 to form a modified portion 6A along the outline of the predetermined removal region R1. Next, removal processing is performed by scanning the pulsed laser beam L2 in a region enclosed by the modified portion 6A.

    Abstract: PROBLEM TO BE SOLVED: To propose a method for generating a three-dimensional microstructure in an object.
    SOLUTION: This manufacturing method prepares a workpiece including a target area corresponding to a position for manufacturing a three-dimensional structure. This target area has a plurality of virtual dwell points. A shaped beam is prepared to be projected on this workpiece. The intersection of the shaped beam with the workpiece defines a beam incident area having a desired shape. This beam incident area is sufficiently large to encompass a plurality of points among the virtual dwell points. The shaped beam is moved so that a different point enters the beam incident area among the virtual dwell points as the beam moves by crossing the workpiece, and so as to cross the workpiece for separating from here, and thereby, allows the different dwell points to stay in the beam incident area over the different time length in scanning of the beam, and provides a different dose to the different points among the virtual dwell points. In this method, a desired dose array of a beam particle is applied onto the target area to form the three-dimensional microstructure.
