英文摘要PURPOSE:To set a die-bonding position accurately and rapidly by applying a laser light to the end face of a semiconductor chip, by inputting an output from a monitoring photodiode to a noise detector, and by moving the semiconductor chip to a position at which noise is detected. CONSTITUTION:A laser light emitted from na position setting semiconductor laser 12 is applied, through convergent lenses 13 and 14, to the luminant end face of a semiconductor chip 4 placed on the top of a block 3, while the semiconductor chip 4 is adsorbed by a vacuum capillary 11 and moved forward and backward. When the luminant end face of the semiconductor chip 4 coincides with the focus F of the lens, the laser light reflected from the luminant end face returns to the position setting semiconductor laser 12. Then noise the generated in an output from a monitoring photodiode, and consequently a luminescent line which is displayed in an image plane of a synchroscope 16 to indicate the intensity of light turns from the state of a smooth straight line to that of oscillations in indentation H. By moving the semiconductor chip 4 to a position at which noise is detected in the image plane of the synchroscope 16, accordingly, a die-bonding position can be set at a position located at a prescribed distance L.
