  • Patent number: 9117763
    Abstract: Semiconductor device identification using quantum dot technology. A semiconductor nanocrystal based target is fabricated. A guard ring superjacent the fluorescing surface of the nanocrystal surface is provided to ensure repeatability of spectral mapping and analysis data. A transparent cap on the target may enhance performance. A system for coding a semiconductor device is described. A method is described for fabricating quantum dot targets in a methodology compatible with subsequent semiconductor fabrication process steps.
    Type: Grant

  • Patent number: 7098490
    Abstract: The present invention provides a GaN based DHFET that helps confine the 2DEG to the channel layer, and reduces the 2DHG. The present invention provides a GaN DHFET having a channel layer comprising GaN and a buffer layer comprising AlxGa1?xN. The Al content in the buffer layer is specifically chosen based on the thickness of the channel layer using a graph. By choosing the Al content in the buffer layer and thickness of the channel layer in accordance with the graph provided in the present invention, the ability of the buffer layer to help confine the 2DEG to the channel layer is improved.
