Abstract
This chip mounting system simultaneously images an alignment mark disposed on a substrate (WT) and an alignment mark disposed on a chip (CP), with the alignment marks disposed on the substrate (WT) and the chip (CP) being separated by a first distance at which the alignment marks fall within a depth-of-field range of imaging devices. The chip mounting system calculates a relative positional deviation amount between the substrate (WT) and the chip (CP) from the imaged images of the alignment marks imaged by the imaging devices and, based on the calculated positional deviation amount, relatively moves the chip (CP) with respect to the substrate (WT) in a direction in which the positional deviation amount therebetween decreases.
