Abstract: PURPOSE: A laser beam attenuator in a laser lift-off apparatus and a laser beam irradiation apparatus having the same are provided to prevent an optical device from being damaged by preventing the unnecessary exposure of laser beams. CONSTITUTION: A laser beam attenuator(100) includes a transparent flat panel(110), a rotating unit(130), a controller, and a housing(150). The transparent flat panel is arranged on a route of laser beams to control the transmission amount of laser beams. The transparent flat panel is arranged on the route of the laser beams emitted from a laser generating unit. The transparent flat panel changes the transmission amount depending on a material. The controller controls an angle of the rotating unit according to preset attenuation. The housing accepts the transparent flat panel and the rotating unit.

Abstract: An apparatus for sorting a semiconductor chip is provided to transmit driving power of a rotatory motor to a rotatory arm by using a pair of eccentric cams and a link for connecting the pair of eccentric cams. A rotatory arm(42) includes a picker(41) formed at one end thereof. A rotatory motor(46) provides rotatory power for rotating the rotatory power so that the picker is moved repeatedly between the wafer and an empty block. The rotatory arm is connected with the rotatory arm by using a pair of eccentric cams and a link connected with the pair of eccentric cams. The pair of eccentric cams include a first eccentric cam(43) connected with a center shaft of the rotatory motor and a second eccentric cam(45) connected with the rotatory arm. The eccentric distance of the first eccentric cam is different from the eccentric distance of the second eccentric cam.
