Abstract:
A method of bondwire integrity testing a packaged IC includes forcing a pin current or pin voltage level sufficient to forward bias a parasitic diode at a plurality of pins relative to a selected reference pin. The pins are connected to bond pads (BPs) on the IC by a bondwire. The bond pads coupled to a diffusion of a first type that forms the parasitic diode (D) with a region doped the second type coupled to a bondpad wirebonded to the reference pin. The resulting pin voltages or pin currents at measured, and present pin-pin relationships are determined. The present pin-pin relationships are compared to stored pin-pin relationship data for a device design of the IC. Results from the comparing are used to determine whether any present pin-pin relationships are significantly different as compared to the stored pin-pin relationships to identify a bondwire problem for at least one pin.

Claim (Index 11):
The test system of  claim 10 , wherein said at least one pin current level comprises first and second pin current levels or said at least one pin voltage level comprises first and second pin voltages levels, and wherein said comparing comprises comparing an impedance.
