A critical parameter in charge-coupled device (CCD) applications using two levels of polycrystalline silicon is the breakdown voltage or breakdown strength of the polyoxide (silicon oxide grown from the first layer of polycrystalline silicon or Poly I) between polycrystalline silicon levels. Two specific treatments performed on Poly I ultimately result in a polyoxide insulator with increased breakdown voltage characteristics for CCD structures.
