    摘要: Electronic apparatus, systems, and methods of forming such electronic apparatus and systems include non-insulating nanocrystals disposed on a dielectric stack, where the non-insulating nanocrystals are arranged to store electric charge. The dielectric stack includes two dielectric layers having different electron barriers such that the non-insulating nanocrystals may be disposed on the dielectric layer having the lower electron barrier.

    摘要: Nanocrystal structures formed using atomic layer deposition (ALD) processes are useful in the formation of integrated circuits such as memory devices. Rather than continuing the ALD process until a continuous layer is formed, the ALD process is halted prematurely to leave a discontinuous formation of nanocrystals which are then capped by a different material, thus forming a layer with a discontinuous portion and a bulk portion. Such nanocrystals can serve as charge-storage sites within the bulk portion, and the resulting structure can serve as a floating gate of a floating-gate memory cell. A floating gate may contain one or more layers of such nanocrystal structures.

    摘要: Embodiments of the present invention describe a semiconductor device having an buffer structure and methods of fabricating the buffer structure. The buffer structure is formed between a substrate and a quantum well layer to prevent defects in the substrate and quantum well layer due to lattice mismatch. The buffer structure comprises a first buffer layer formed on the substrate, a plurality of blocking members formed on the first buffer layer, and second buffer formed on the plurality of blocking members. The plurality of blocking members prevent the second buffer layer from being deposited directly onto the entire first buffer layer so as to minimize lattice mismatch and prevent defects in the first and second buffer layers.
