Abstract
With an assumption that the three data of the position (X, Y) of the first positioning patternand position (X, Y) of the second positioning patternof the reference chip, and the position (X, Y) of the first positioning patternof the bonding object chip, as well as the length L of a line segment connecting (X, Y) and (X, Y), and the angle θof this line segment with respect to the X axis, are known, the coordinates (X, Y) of the center position of the imaging rangethat is to be imaged next is determined by detecting the inclination-angle Δθ of the first positioning patternof the bonding object chip. Furthermore, the imaging range can be narrowed and the second positioning patterncan be captured by increasing the precision of Δθ.
