Failure Analysis Applications

We provide industry leading processes and tools for FA dry etch de-processing.

Yield management is a key factor in semiconductor manufacturing. To improve yield one key technique is the de-processing of a failed chip or wafer to find and analyse the failure point in order to eliminate it. 

Featured Solutions

  • Isotropic polyimide removal (RIE or ICP mode)
  • Isotropic Nitride (passivation) removal (PE or ICP mode)

  • Metal skeleton removal (RIE or ICP mode)
  • Poly-Si removal (RIE mode)
  • Al and Cu removal (ICP mode)
  • Backside Bulk Si removal (ICP mode)

For analysis or defect identification to be performed the device must be suitably prepared, this becomes more challenging as device architectures become ever more 3-dimensional. Plasma assisted etch and deposition are used to ensure accurate, quickly achieved results.

Oxford Instruments’ flexible Failure Analysis (FA) tools allow a wide range of processes, able to process small die or packaged devices through to 300mm wafers. Well controlled processing means that there is no damage to the metal conducting tracks.
