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.

Conductivity improvements in III-V semiconductor devices are described. A first improvement includes a barrier layer that is not coextensively planar with a channel layer. A second improvement includes an anneal of a metal/Si, Ge or SiliconGermanium/III-V stack to form a metal-Silicon, metal-Germanium or metal-SiliconGermanium layer over a Si and/or Germanium doped III-V layer. Then, removing the metal layer and forming a source/drain electrode on the metal-Silicon, metal-Germanium or metal-SiliconGermanium layer. A third improvement includes forming a layer of a Group IV and/or Group VI element over a III-V channel layer, and, annealing to dope the III-V channel layer with Group IV and/or Group VI species. A fourth improvement includes a passivation and/or dipole layer formed over an access region of a III-V device.

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.
