Integration of Silicon Nanocrystal Memory Arrays with HfAlOx Based Interpoly Dielectric

The integration of silicon nanocrystal (Si-nc) nonvolatile memory (NVM) arrays with HfAlOx based interpoly dielectric (IPD) is presented for the first time. The data obtained on array vehicles programmed in Fowler-Nordheim operation regime are in excellent agreement with previously presented results on single cells, as well as theoretical data and allow the evaluation of the scalability of the Si-nc concept.
