    摘要: A method is disclosed for producing semi-insulating silicon carbide crystal with a controlled nitrogen content. The method includes the steps of introducing an ambient gas containing hydrogen into a sublimation growth chamber, heating a silicon carbide source powder to sublimation in the hydrogen ambient growth chamber while, heating and then maintaining a silicon carbide seed crystal in the hydrogen ambient growth chamber to a second temperature below the temperature of the source powder, at which second temperature sublimed species from the source powder will condense upon the seed crystal, continuing to heat the silicon carbide source powder until a desired amount of silicon carbide crystal growth has occurred upon the seed crystal, while maintaining an ambient concentration of hydrogen in the growth chamber sufficient to minimize the amount of nitrogen incorporated into the growing silicon carbide crystal, and while maintaining the source powder and the seed crystal during sublimation growth at respective temperatures high enough to increase the number of point defects in the growing crystal to an amount that renders the resulting silicon carbide crystal semi-insulating.

    摘要: A garment for the transporting, observing, entertaining, training, and displaying of small animals, reptiles and insects (gerbils, mice, snakes, tarantulas, spiders, lizards, etc.) in the tunnels of the garment while on the shoulders of their owners. The garment consists of a see-through, mesh washable fabric panel on top and a brightly colored washable panel underneath, attached to each other using releasable fasteners. The fasteners also provide means to construct tunnel walls and nesting areas for the small animal. The fasteners further provide attachment to the garment tunnel's floor and walls for toys and other paraphernalia to entertain the pet and adorn the garment. This garment allows the owner to hold, observe, and transport his pet without damaging or soiling his clothes while his pet has a tunnel in which to play and rest safely. Also the owner can remove toys, food and nesting material in order to launder the garment.

    摘要: The invention is a method of inspecting a semiconductor wafer surface for scratches. The method includes positioning a semiconductor wafer for illumination by a radiation source and adjacent a background material that will absorb radiation from the radiation source, directing radiation at a surface of the wafer from the radiation source that has a wavelength that will be absorbed by the fundamental absorption of the wafer, filtering or otherwise limiting the radiation to allow only radiation having wavelengths that are absorbed by the fundamental absorption of the wafer to pass, and detecting radiation scattered on the surface of the wafer and filtered, by position, to thereby identify the location of the scratches on the surface of the wafer, while the absorption of the background material prevents other radiation from the source from interfering with the detection of the scratch-scattered radiation.
