Abstract
A technique is provided which can exactly recognize a chip to be picked up when picking up the chip from a wafer sheet in a process of die bonding a thin chip. A camera is coupled to one end of a lens barrel, an objective lens is attached to an opposite end of the lens barrel, and an image of a main surface of a chip is photographed through the objective lens. A surface-emitting lighting unit, a diffusing plate and a half mirror are internally provided between the lens barrel and the chip. Further, another lens barrel having a coaxial drop lighting function of radiating light to the main surface of the chip along the same optical axis as that of the camera is disposed.
