Abstract

By utilizing a NdYAG lamp pumped marking laser, along with unique mixes of specific acids, reproducible decapsulation of copper bonded devices without damage to the bond wires, packaging material, or to the silicon die circuitry itself can be achieved. With the copper bond wires, die, or substrate exposed, typical failure analysis methodology can then be applied to drive root cause failure analysis or device characterization.
