Abstract
A computerized system and method for reducing bond program errors in a slave bonder, prepared to attach connecting bonds onto bond pads of a slave integrated circuit, by first collecting, on a master bonder, input data concerning bond x-y locations, alignment reference x-y locations, and alignment reference images from a master integrated circuit, then analyzing these data to construct a network of relationships between reference images and bond locations, and store data and relationships in a master file. Secondly, on a slave bonder, all this information is automatically retrieved and compared by a computer with input data concerning alignment reference images from a slave circuit. Thirdly, any discrepancy found is corrected by a computer to identify the new bond locations on the slave circuit. Finally, the slave bonder attaches the connecting bonds based on the computed correct bond locations.
