Patent number: 5970381Abstract: A method is provided that produces a good, strong organic monomolecular film having its atoms arranged in a three-dimensionally ordered manner by cleaving a III-V group compound semiconductor substrate in film formation molecules or in a solution containing them, in order to cause selective chemisorption which forms a monomolecular film and then deposits another layer of organic molecule film. In this method, the III-V group compound semiconductor substrate is cleaved in a solution containing SH groups dissolved into a solvent in order to form a self-assembled monolayer and is then placed in another solution, where metallic ions are adsorbed to the surface of the film or where the functional groups are converted by chemical treatment. The substrate is then immersed in a solution containing organic molecules that are selectively chemisorbed to the functional groups.Type: GrantFiled: September 5, 1997Date of Patent: October 19, 1999Assignee: National Institute for Advanced Interdisciplinary ResearchInventors: Hirotaka Ohno, Larry A.

Patent number: 5795699Abstract: A method for forming upon a reflective layer, such as a reflective conducting layer, within an integrated circuit an Anti-Reflective Coating (ARC) which simultaneously possesses adhesion promotion characteristics for an organic layer to be formed upon the reflective layer. There is first formed upon a semiconductor wafer a reflective integrated circuit layer which may be a hydrophilic reflective integrated circuit layer or a hydrophobic integrated circuit layer. The semiconductor wafer is then immersed into and withdrawn from a Langmuir trough having formed therein a Langmuir-Blodgett (LB) monolayer film of a dye surfactant molecule ordered upon a surface of water. Upon withdrawing the wafer from the Langmuir trough, there is formed upon the reflective integrated circuit layer an ordered LB film of the dye surfactant molecule. The chromophore groups within the dye surfactant molecule and ordered LB film provide ARC characteristics to the reflective layer.Type: GrantFiled: July 15, 1996Date of Patent: August 18, 1998Assignee: Chartered Semiconductor Manufacturing Ltd.Inventors: Mei Sheng Zhou, Ron-Fu Chu

Patent number: 5661092Abstract: Ultra thin organo-ceramic and metal oxide films are prepared under room temperature and atmospheric conditions by exposing .alpha.,.omega.-functional siloxane oligomers and fatty acid metal soaps, respectively, to a combination of ultraviolet light (UV) and ozone (O.sub.3). The process includes the steps of preparing ultra thin .alpha.,.omega.-functional polysiloxane and fatty acid metal soap films using, but not limited to, the Langmuir-Blodgett (LB) technique. The LB technique permits construction of molecular monolayer or multilayer films on a variety of substrates. By using carboxylic acid end groups on the siloxane oligomers, metal ions can be incorporated into the SiOx film after UV-ozone exposure. This technique can be used to make electronically, optically, and chemically important organo-ceramic and metal oxide films on temperature sensitive substrates.Type: GrantFiled: September 1, 1995Date of Patent: August 26, 1997Assignee: The University of ConnecticutInventors: Jeffrey T.
