Abstract
A computerized system and method for recreating illumination conditions in a slave bonder, prepared to attach connecting bonds onto bond pads of a slave integrated circuit. First, images of illuminated alignment references of a master circuit on a master bonder are defined; these data are analyzed to construct relationships between reference images and bond locations; data and relationships are stored in a master file. Secondly, on a slave bonder, the master reference image data are regenerated so that the illumination conditions of the slave bonder, as based on images, are recreated. Thirdly, images of the slave circuit references are produced under the newly created illumination conditions, and the alignment references are compensated. Finally, the bonding locations of the slave circuit and the bonding program of the slave bonder are corrected so that connecting bonds can be attached onto the recomputed correct bond locations.
