Patent ID: 7931186

Claim:
A method of teaching an eyepoint for a wire bonding operation, the method comprising the steps of: (1) selecting a group of shapes from a region of a semiconductor device for use in teaching an eyepoint, the group of shapes including at least one of (a) bond pad shapes, (b) fiducial shapes, and (c) circuitry shapes; and (2) teaching the eyepoint to a wire bonding machine using at least one of (a) a sample semiconductor device, or (b) predetermined data related to the semiconductor device, wherein a respective one of the eyepoint of another semiconductor device to be wire bonded is configured to be scanned during a subsequent pattern recognition operation, the teaching step including defining locations of each of the shapes with respect to one another, the teaching step also including using an algorithm to preclude predetermined areas of the region from being included in the eyepoint such that the predetermined areas are at least one of (i) scanned and given no weight during the pattern recognition operation, (ii) scanned but given less weight than the eyepoint during the pattern recognition operation, and (iii) not scanned at all during the pattern recognition operation, the predetermined areas including at least one of (1) interior portions of each of the shapes, and (2) portions of the region between ones of the shapes.
