Patent number: 6759098Abstract: Low dielectric constant film materials with improved elastic modulus. The method of making such film materials involves providing a porous methyl silsesquioxane based dielectric film material produced from a resin molecule containing at least 2 Si—CH3 groups and plasma curing the porous film material to convert the film into porous silica. Plasma curing of the porous film material yields a film with improved modulus and outgassing properties. The improvement in elastic modulus is typically greater than or about 100%, and more typically greater than or about 200%. The plasma cured porous film material can optionally be annealed. The annealing of the plasma cured film may reduce the dielectric constant of the film while maintaining an improved elastic modulus as compared to the plasma cured porous film material. The annealed, plasma cured film has a dielectric constant between about 1.1 and about 2.4 and an improved elastic modulus.Type: GrantFiled: July 16, 2001Date of Patent: July 6, 2004Assignees: Axcelis Technologies, Inc., Chemat Technology, Inc.Inventors: Qingyuan Han, Carlo Waldfried, Orlando Escorcia, Ralph Albano, Ivan L.

Patent number: 6383406Abstract: Insertion of light elements such as H,C, or N in the R2Fe17 (R=rare earth metal) series has been found to modify the magnetic properties of these compounds, which thus become prospective candidates for high performance permanent magnets. The most spectacular changes are increases of the Curie temperature, Tc, of the magnetization, Ms, and of coercivity, Hc, upon interstitial insertion. A preliminary product having a component R—Fe—C,N phase is produced by a chemical route. Rare earth metal and iron amides are synthesized followed by pyrolysis and sintering in an inert or reduced atmosphere, as a result of which, the R—Fe—C,N phases are formed. Fabrication of sintered rare earth iron nitride and carbonitride bulk magnet is impossible via conventional process due to the limitation of nitridation method.Type: GrantFiled: May 25, 2000Date of Patent: May 7, 2002Assignee: Chemat Technology, Inc.Inventors: Yuhong Huang, Qiang Wei, Haixing Zheng

Patent number: 6168694Abstract: Metal nitride, carbonitride, and oxycarbonitride powder with high surface area (up to 150 m2/g) is prepared by using sol-gel process. The metal organic precursor, alkoxides or amides, is synthesized firstly. The metal organic precursor is modified by using unhydrolyzable organic ligands or templates. A wet gel is formed then by hydrolysis and condensation process. The solvent in the wet gel is then be removed supercritically to form porous amorphous hydroxide. This porous hydroxide materials is sintered to 725° C. under the ammonia flow and porous nitride powder is formed. The other way to obtain high surface area nitride, carbonitride, and oxycarbonitride powder is to pyrolyze polymerized templated metal amides aerogel in an inert atmosphere. The electrochemical capacitors are prepared by using sol-gel prepared nitride, carbonitride, and oxycarbonitride powder. Two methods are used to assemble the capacitors.Type: GrantFiled: February 4, 1999Date of Patent: January 2, 2001Assignee: Chemat Technology, Inc.Inventors: Yuhong Huang, Oiang Wei, Chung-tse Chu, Haixing Zheng
