ABSTRACT:
In a die-bonding machine for picking up a number of semiconductor pellets arranged in the form of a pellet array, one by one, to place a picked-up semiconductor pellet on a predetermined position, when an estimated X-direction coordinate position of the semiconductor pellet to be picked up in relation to the pellet supporting and displacing mechanism is assumed as being "x" by considering a center point of the pellet supporting and displacing mechanism as the origin of the coordinates in the X direction, the pellet supporting and displacing mechanism and the pellet picking-up and carrying mechanism are displaced so that an X-direction coordinate position PX of the pick-up position takes a position expressed by the following equation (1) and an X-direction coordinate position CX of the center point of the pellet supporting and displacing mechanism takes a position expressed by the following equation (2):
