  • Publication number: 20080227239
    Abstract: A semiconductor-chip exfoliating device for exfoliating a semiconductor chip 1 from an adhesive sheet 6 is provided. The device includes a backup holder 28 for holding the adhesive sheet 6 so that semiconductor chips 1 turn upward, a pair of needle pins arranged on a backside of the holder 28 to lift off the adhesive sheet 6 from the holder 28 through through-holes 31a, 31b in the holder 28 and a sliding unit 33 arranged on the backside of the holder 28 to slide one needle pin 30b in a direction to depart from the other needle pin 30a. By the sliding unit 33, the interval between the needle pins 30a, 30b can be changed so as to cope with a variation of semiconductor chips 1, 1A.

  • Publication number: 20040218636
    Abstract: A laser apparatus comprises a semiconductor laser element which emits a light beam with a spread in a slow-axis direction and a fast-axis direction, a fast-axis collimating lens which controls the spread in the fast-axis direction of the light beam emitted from the semiconductor laser element, a reflector which returns the light beam emitted in the slow-axis direction in a specific angle range to the semiconductor laser element, a reflector supporting member which supports the reflector, and a side support member which supports the fast-axis collimating lens and the reflector supporting member in the slow-axis direction with respect to the semiconductor laser element.
