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.

In one aspect, a method includes forming a silicon dioxide layer on a surface of a diamond layer disposed on a gallium nitride (GaN)-type layer. The method also includes etching the silicon dioxide layer to form a pattern. The method further includes etching portions of the diamond exposed by the pattern.

Fabricating a device with a diamond layer

The present invention is directed to a method for fabricating a thermal management substrate having a Silicon (Si) layer on a polycrystalline diamond film, or on a diamond-like-carbon (DLC) film. The method comprises acts of fabricating a separation by implantation of oxygen (SIMOX) wafer; depositing a polycrystalline diamond film onto the SIMOX wafer; and removing various layers of the SIMOX wafer to leave a Si overlay layer that is epitaxially fused with the polycrystalline diamond film. In the case of the DLC film, the method comprises acts of ion-implanting a Si wafer; depositing an amorphous DLC film onto the Si wafer; and removing various layers of the Si wafer to leave a Si overlay structure epitaxially fused with the DLC film.

Thermal management substrate

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 AlGaN. 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.
