Abstract: A method of fabricating a semiconductor device is disclosed. The method comprises patterning a photoresist over a compound semiconductor substrate; reducing a width of the photoresist; forming a hardmask over the substrate and not over the photoresist; removing the photoresist; etching to form and opening down to the substrate; forming a gate in the opening; and removing the hardmask except beneath the gate.

Abstract: Methods of fabricating compound semiconductor devices are described.

Abstract: A method of fabricating a semiconductor device, the method comprises forming a mask layer over a compound semiconductor substrate; and patterning a photoresist over the mask layer. The method comprises etching a portion of the mask layer beneath the photoresist; forming a hardmask over the substrate and not over the mask layer; removing the mask layer; etching to form and opening down to the substrate; and forming a gate in the opening.

Abstract: A personal care composition that comprises a synthetic random polymer comprising a net positive charge; said synthetic random polymer comprising an acrylamide monomer unit; and a cationic monomer unit comprising 3 or more positive charges; wherein said synthetic random polymer comprises a ratio of said acrylamide monomer unit to said cationic monomer unit comprising from about 55:45 to about 97:3; and a surfactant component; and an aqueous carrier.

Abstract: Disclosed are methods for designing and employing a portable device for effecting a desired environment proximate to the device (including carrying out such methods under business arrangements encompassing two or more business entities). The effected environment includes, in part, temporary increases in the amount of water vapor as the device emits water vapor over some time duration, typically from about 1 or 2 minutes or so to about 15 to 30 minutes or so. Heat from a chemical heating engine is employed to drive off the water vapor. The device may also emit one or more ingredients adapted to be detected by olfaction. The device may be used to help address symptoms of various ailments, e.g., cold, flu, allergies, sinusitis, and the like. Also, the device may be employed to help promote a desired emotive state for the user of the device. The device promotes one or more desired states through auditory, tactile, visual, and/or olfactory signals.
