Abstract:
The present invention relates to a detection circuitry for detecting bonding conditions on segmented bond pads of a semiconductor device, the bonding conditions representing good or bad contacts on the bond pads. The detection circuitry comprises a segmented bond pad (1, 11) having at least two parts (2, 3, 12, 13) being electrically separated from each other, and a supplying unit (S1, S2, R1, R2) being adapted for supplying predetermined signals to at least one of the at least two parts of the segmented bond pad. Furthermore, a detector (4, 14) is provided for receiving from at least one of the at least two parts of the segmented bond pad sensing signals derived from said predetermined signals, and for determining the bonding conditions based on said received sensing signals indicative of a good or bad bonding contact on the segmented bond pad.
