    摘要: The present invention discloses a non-volatile memory cell structure utilizing a charge trapping high-k dielectric in the place of the triple film stack (tunnel dielectric layer/charge trapping layer/blocking layer). The charge trapping characteristic of the high-k dielectric can be further improved by exposing the high-k dielectric layer to an treatment process such as a plasma exposure using excited state oxygen (e.g. oxygen plasma) ambient. By using a single layer as the charge trapping gate dielectric, the present invention presents a simple and inexpensive solution that permits device scaling to very small dimensions, together with the ease of device fabrication processes. The present invention also discloses the fabrication process for the charge trapping high-k gate dielectric non-volatile memory cell structure, applicable to bulk device, TFT device or SOI device.

The SiOXNY thin-film can be stoichiometric or non-stoichiometric. The SiOXNY thin-film can be graded, meaning the values of X and Y vary with the thickness of the SiOXNY thin-film. Further, the process enables the in-situ deposition of a SiOXNY thin-film multilayer structure, where the different layers may be stoichiometric, non-stoichiometric, graded, and combinations of the above-mentioned types of SiOXNY thin-films.

    摘要: A method is provided for forming a silicon nitride (SiNx) film. The method comprises: providing a Si substrate or Si film layer; optionally maintaining a substrate temperature of about 400 degrees C., or less; performing a high-density (HD) nitrogen plasma process where a top electrode is connected to an inductively coupled HD plasma source; and, forming a grown layer of SiNx overlying the substrate.

The SiNx layer can be grown at an initial growth rate of at least about 20 Å in about the first minute.
