    摘要: The invention relates to a method for picking up semiconductor chips from a wafer table and, optionally, their mounting on a substrate by means of a pick-and-place system. The position and orientation of the semiconductor chip to be mounted next are determined by means of a first camera and made available in the form of positional data relating to a first system of coordinates. The position and orientation of the substrate place on which the semiconductor chip will be mounted are determined by means of a second camera and made available in the form of positional data relating to a second system of coordinates. The conversion of coordinates of the first or second system of coordinates into coordinates of motion of the pick-and-place system occurs by means of two fixed mapping functions and two changeable correction vectors. The correction vectors are readjusted on the occurrence of a predetermined event.

    摘要: The detachment and removal of a semiconductor chip from a foil occurs in accordance with the invention in three phases. In the first phase there is a partial detachment of the semiconductor chip from the foil with mechanical means, but without the participation of a chip gripper. In the second phase the semiconductor chip is further detached from the foil, with the semiconductor chip being held by the chip gripper. In the third phase the chip gripper is lifted and moved away.

    摘要: In order to eliminate the inclination of a semiconductor chip picked by a gripper, the height of at least three points on the underneath of the semiconductor chip is determined in relation to a reference surface and from this the inclination is calculated. Determining the heights takes place in that the semiconductor chip is lowered until the semiconductor chip comes into contact with a needle.
