Abstract: A first die has a port to couple the first die to a second die over a die-to-die interconnect. The port includes circuitry to implement a physical layer of the die-to-die interconnect, send first protocol identification data over the physical layer to identify a first protocol in a plurality of protocols, send first data over the interconnect to the second die, wherein the first data comprise data of the first protocol, send second protocol identification data over the physical layer to identify a different second protocol in the plurality of protocols, and send second data over the interconnect to the second die, wherein the second data comprise flits of the second protocol.

Abstract: The present invention includes systems and compositions of holographic grating structures devices and methods for fabricating such holographic grating structures. The method comprises the steps of preparing a composite mixture comprising a polymerizable matrix, a liquid crystal, and a photo-oxidant dye, producing an interference pattern from two interference beams, wherein the two interference beams originate from a recording laser beam directed by a low energy laser, and projecting the interference pattern on the composite mixture to form a holographic grating structure. As described, the holographic grating structure yields a first-order diffraction efficiency of at least about 30% diffraction efficiency which may be adjusted by the application of an electric field.

Abstract: Generally, and in one form, the present invention is a device for the measurement of radiant energy using a polymer dispersed liquid crystal cell. In another form, the present invention is a device for the detection of ionizing radiation that uses a polymer dispersed liquid crystal cell and a light source that is optically oriented toward the cell. The cell is connected to an electrical signal generator, and a light detector capable of producing output is optically aligned with the light source. Finally, a computer is connected to the light detector to analyze the output from the light detector.

Abstract: A method and apparatus for rapidly yet nondestructively testing a semiconductor wafer is disclosed. A multi-spot positron source assembly directs positrons over an entire semiconductor wafer at one time. A pair of multi-detector assemblies are situated so that each detector within an assembly corresponds physically with a positron source. By measuring the characteristic emission and annihilation energies, the multi-detector assembly pair is capable of detecting the lifetimes of positrons from within each of the areas simultaneously. Longer lifetimes are indicative of defects within the semiconductor wafer. By accumulating and analyzing positron lifetimes from across the entire wafer substantially simultaneously, information about the existence and location of defects in the wafer may be more rapidly determined than is possible with known positron-emission techniques.
