SUMMARY: The inventions listed below are owned in whole or in part by the U.S. Government, as represented by the Department of Commerce. The Department of Commerce's ownership interest in the inventions are available for licensing in accordance with 35 U.S.C. 207 and 37 CFR Part 404 to achieve expeditious commercialization of results of Federally funded research and development. FOR FURTHER INFORMATION CONTACT: Technical and licensing information on these inventions may be obtained by writing to: National Institute of Standards and Technology, Industrial Partnerships Program, Building 820, Room 213, Gaithersburg, MD 20899; Fax 301-869-2751. Any request for information should include the NIST Docket No. and Title for the relevant invention as indicated below. SUPPLEMENTARY INFORMATION: NIST may enter into a Cooperative Research and Development Agreement (``CRADA'') with the licensee to perform further research on the inventions for purposes of commercialization. The inventions available for licensing are: NIST Docket Number: 94-020/030. Title: Miniature X-Ray Source. Abstract: The invention is jointly owned by the U.S. Government, as represented by the Secretary of Commerce, and the United States Navy. The United States Navy has transferred custody of their interest in the invention to the National Institute of Standards and Technology. A miniature x-ray source only a few millimeters across has applications as an x-ray source for a number of medical applications including non- invasive intracavitary radiotherapy, diagnostic medical x-ray imaging, and intraoperative radiotherapy. Also, for example, an x-ray source according to the invention may be placed in the mouth of a patient and an x-ray film placed outside the mouth so as to obtain an image of the mandibular joint close to the ear. Other scientific applications for this tiny radiation source include small x-ray microscopes, fluorescence analysis absorptometry, radiography and x-ray tomography. The miniature x-ray source has a cathode which may comprise a gated array of field emission elements, an array of solid state miniature thermionic cathodes, or ferroelectric cathodes. Each of these cathodes can be manufactured using photolithographic and etching techniques commonly found in the semiconductor industry. The anode may be a foil, a thin film of metal deposited on the inside surface of a wall of the evacuated chamber or a self-supporting body of a metal that produces x- rays in response to electron impacts. NIST Docket Number: 95-036US. Title: X-Ray Lithography Mask Inspection System. Abstract: The invention is jointly owned by the U.S. Government, as represented by the Secretary of Commerce, and Wisconsin Alumni Research Foundation. The invention uses an x-ray conversion microscope to form an enlarged image of the actual x-ray pattern that an x-ray mask would project onto a resist. Present x-ray mask inspection is done by electron microscopes where the image produced is representative of the interaction of high energy electrons with the features on the mask. The proposed technique would instead form images from the x-ray transmission of the mask, the quantity most relevant to the mask's performance in the x-ray lithography process. NIST Docket Number: 96-022US. Title: Methods For Machining Hard Materials Using Alcohols. Abstract: This invention is jointly owned by the U.S. Government, as represented by the Secretary of Commerce, and the University of Maryland. The present invention provides a method for machining hard materials using the machining fluids containing long chain alcohol in which the machining fluid is applied to a machining tool and then lubricates the machining of the workpiece by the [[Page 37094]] machining tool and protects the machining tool during machining. The method is particularly useful when used with machining tools having a Mohs hardness of at least 9 and is most particularly useful when used with diamond machining tools. NIST Docket Number: 97-014US. Title: Microroughness-Blind Optical Scattering Instrument. Abstract: A microroughness-blind optical scanner for detecting particulate contamination on bare silicon wafers focuses p-polarized light onto the surface of a sample. Scattered light is collected through independently rotatable polarizers by one or more collection systems uniformly distributed over a hemispherical shell centered over the sample. The polarizer associated with each collection system is rotated to cancel the corresponding Jones vector, thereby preventing detection of microroughness-scattered light, yielding higher sensitivity to particulate defects. The sample is supported on a positioning system permitting the beam to be scanned over the sample surface of interest. Dated: July 2, 1998. Robert E. Hebner, Acting Deputy Director.
