  • Patent number: 10525553
    Abstract: A laser processing device includes: a laser light source emitting laser light; a converging optical system converging the laser light at an object to be processed; a reflective spatial light modulator modulating the laser light such that the laser light is caused to branch into 0th order light and ±nth order light (n is a natural number) including at least first processing light and second processing light, and the first processing light is converged at a first converging point and the second processing light is converged at a second converging point; and a light blocking part blocking light to be converged at an outside with respect to the first processing light and the second processing light of the 0th order light and the ±nth order light to be converged at the object.

  • Patent number: 10328521
    Abstract: A laser processing device includes: a laser light source; a converging optical system; and a reflective spatial light modulator modulating the laser light such that the laser light is caused to branch into at least first processing light and second processing light, and the first processing light is converged at a first converging point and the second processing light is converged at a second converging point. In a case in which W1 is a radius of the first processing light at a front face of the object, W2 is a radius of the second processing light at the front face, and D is a distance between the first converging point and the second converging point when viewed from a direction orthogonal to the front face, the reflective spatial light modulator modulates the laser light such that D>W1+W2 is satisfied.

  • Publication number: 20170031629
    Abstract: There is provided a method of transferring a binary image into a memory device having a memory controller for performing conversion between physical addresses and logical addresses of storage areas. The binary image is transferred into the memory device such that areas included in the binary image and having no valid data become free areas in storage areas of the memory device, the free areas to which physical addresses and logical addresses are not associated.
