Patent number: 6610457Abstract: A bottom antireflective coating layer is made from the compositions of organic photosensitive materials that contain isoflavone chromophore by photolithography utilizing a deep ultraviolet light source for producing a submicro-level, large-scale integrated chip. A copolymer containing an isoflavone chromophore is used as a bottom antireflective coating layer for fabricating a 64-megabit or gigabit DRAM. The antireflective coating layer enables not only the suppression of reflections of light that occur under the substrate layer but also the removal of standing waves. Consequently, a high-resolution sub-micron of a 100˜200 nm integrated circuit is able to be stably formed. Therefore, it is possible to increase the production of semiconductors.Type: GrantFiled: October 15, 2001Date of Patent: August 26, 2003Inventors: Jun Young Kim, Sung Hyun Ha, Kwang Duk Ahn, Jong Hee Kang

Patent number: 6605253Abstract: The presently disclosed disinfection process for use in the processing of foodstuffs is designed as an intervention step in poultry processing to allow for continuous on-line processing of poultry carcasses that may have accidentally become contaminated during the evisceration process. Such on-line processing is designed to replace the need for off-line manual washing and cleaning of the contaminated carcasses. By eliminating such off-line manual washing, food safety will be enhanced due to the elimination of the physical handling of carcasses and the cross-contamination that may result from such physical handling. An additional benefit is that the production process will also be able to run with a reduced number of interruptions, which will result in a more efficient production process.Type: GrantFiled: June 9, 2000Date of Patent: August 12, 2003Assignee: Zentox CorporationInventor: Michael Perkins

Patent number: 5753493Abstract: The instant invention is an egg wash decontaminating solution and process. The decontaminating solution and process allows for reducing the surface tension of a biofilm allowing for the removal of the biofilm and control of underlying bacteria. A solution of triterpene saponin provides the surface tension wherein an optional soft acid such as food grade sodium lactate operates to control the bacteria. The saponin further acts as a foaming agent providing visual indication of operation while holding matter in suspension.Type: GrantFiled: March 20, 1996Date of Patent: May 19, 1998Assignee: Nouveau Technologies, Inc.Inventor: Jack G.

Patent number: 5750165Abstract: A method of processing an ESL (extended shelf-life) refrigerated potato product (various cuts) is disclosed. The product is acid blanched when pasteurized and then "seeded" with lactic acid starter culture. The prepared product line has desirable organoleptic qualities and can be stored at refrigerated temperatures typical of commercial retail stores (30.degree.-56.degree. F.) as well as the home refrigeration system. The products have been proven to be pathologically safe when exposed to extended periods of temperature abuse.Type: GrantFiled: April 16, 1996Date of Patent: May 12, 1998Inventor: Dale E. Erway
