  • Process and apparatus for fabricating nano-floating gate memories and memory made thereby
    Patent number: 7585721
    Abstract: In a process for fabricating a nano-floating gate memory structure, a substrate and a nanocluster source are firstly provided. The nanocluster source is activated for generating a beam of nanoclusters towards the substrate, and at least part of the nanoclusters are received atop the substrate. Thereby, a plurality of nanoclusters of controllable size are formed atop the substrate.
    Type: Grant
