摘要:
Various techniques permitting fabrication of superconducting integrated circuits and structures including Josephson junctions, which may be useful in quantum computers, are disclosed. For instance, a superconductor/insulator/superconductor trilayer structure may be patterned by etching the upper superconductor layer using a hard mask which is lithographically patterned using a photoresist mask.

摘要:
Vertical field effect transistors having a channel region defined by at least one semiconducting nanotube and methods for fabricating such vertical field effect transistors by chemical vapor deposition using a spacer-defined channel. Each nanotube is grown by chemical vapor deposition catalyzed by a catalyst pad positioned at the base of a high-aspect-ratio passage defined between a spacer and a gate electrode. Each nanotube grows in the passage with a vertical orientation constrained by the confining presence of the spacer. A gap may be provided in the base of the spacer remote from the mouth of the passage. Reactants flowing through the gap to the catalyst pad participate in nanotube growth.

An apparatus for surface inspection and processing of a wafer (12) includes a microcolumn (14) and an associated scanning probe microscope (16). The microcolumn enables high speed scanning of the wafer at a relatively high resolution, while the scanning probe microscope provides atomic resolution of highly localized areas of the wafer. The microcolumn and scanning probe microscope can be partially fabricated out of the same substrate. Additionally, the microcolumn and scanning probe microscope can be a portion of an array of microcolumns and/or scanning probe microscopes. The apparatus may be used for imaging, lithography and spectroscopy.

摘要:
The present invention relates to a visual indicating device and an article for controlling odors, in particular foot, garbage, basement, cooking, pet, tobacco, feces and urine odors. The article comprises a visual indicating agent that is color sensitive to the odor, and optionally, an odor absorbing agent. The visual indicating agent changes color when the article has been exposed to a sufficient amount of odor to saturate the article. The indicating agent may be applied in differing concentrations to two or more zones so as to indicate to a user of the article how much of the odor absorbing capacity has been used, or conversely, how much of the odor absorbing capacity remains. Suitable visual indicating agents that change color in response to odors are also described. The article for controlling odors may be a disposable odor absorbing sheet, air freshening product, diaper, undergarment pad, face mask, air filtration device, sanitary napkin, tampon, panty shield or incontinence pad.
