dc.description.abstract | A new nonvolatile memory with high density, and high work-function metal nanodots, metal nanodot (MND) memory, was proposed and fundamental characteristics of MND capacitor were evaluated. In this work, a nanodot layer of FePt with high density and high work-function (similar to 5.2eV) was fabricated as a charge,storage site in nonvolatile memory, and its electrical characteristics were evaluated for the possibility of nonvolatile memory in view of cell operation by Fowler-Nordheim (FN) tunneling. Here, a nanodot FePt layer was controlled as a uniform single layer with dot size of of under similar to 2 nm and dot density of similar to 1.2 x 10(13)/cm(2). Electrical measurements of metal-oxide-semiconductor (MOS) structure with FePt nanodot layer shows a threshold voltage window of similar to 6 V using FN programming and erasing, which is satisfactory for operation of the non-volatile memory. Furthermore, this structure provides better data retention characteristics compared to other metal dot materials with similar dot density in our experiments. From these results, it is expected that this nonvolatile memory using an FePt nanodot layer with high dot density and high work-function can be a candidate structure for the future nonvolatile memory. | - |
