Publication number: 20120046480Abstract: The disclosure provides a dense Cu thin film, a dense CuO thin film and the manufacturing process applied in metallization process of ultra-large scale integration (ULSI), which uses a two-step growth consisting of pre-deposition and annealing to form a dense Cu thin film or a dense CuO thin film. In the process, a copper-containing metal-organic complex is used as precursor and a reducing gas is used as carrier gas. The precursor is carried to a reactive system with a substrate by a carrier gas and pre-deposit a CuO thin film on the substrate under lower temperature. Next, stop supplying the precursor and raise the temperature or offer other energy to anneal the thin film with hydrogen gas or reducing gas, which reduces the CuO thin film to a smooth and dense Cu thin film. Then, choosing oxide containing gas as the react gas obtains the CuO thin film.Type: ApplicationFiled: August 20, 2010Publication date: February 23, 2012Inventors: Cheng-Jye Chu, Chih-Hung Chen

Publication number: 20100216941Abstract: A silane-curing chemical resistant coating composition and methods for making and using the composition are provided. A coating can be manufactured, for example, by two simultaneous or sequential processes. In the first process an inorganic material such as silica or alumina with free amine or hydroxyl sites reacts with an organic moiety having a terminating functional group, such as an oxirane, amine or hydroxyl. In the second process, the material further reacts with an isocyanato, amino or other functional alkoxy, methoxy, acyloxy or other silane group. The terminal functional becomes an alkoxy, methoxy, alcyloxy or other silane that can cross-link with another such silane group on contact with moisture and/or upon absorption of ultraviolet light. Optionally, silane terminated polymers may be further added to contribute flexibility, hardness and other desirable physical properties.Type: ApplicationFiled: August 17, 2009Publication date: August 26, 2010Applicant: ISOTRON CORPORATIONInventors: Henry LOMASNEY, Brenden Carlson

Patent number: 7772415Abstract: Infrared (IR) radiation absorbing compounds of metal or metalloids with ligands are beneficial for many applications. Schiff base biquinone (SBB) ligands surrounding a metal or metalloid center may be used for laser welding applications, as one example, wherein effective infared radiation absorption and heat resistance are required. These compounds may be known as Schiff base biquinone metal complexes (SBBC's). The compositions and methods of this invention provide examples of many different NIR absorbing compounds that exhibit high NIR absorbing strength, good thermal stability, and relatively low visible color. The IR absorbing compounds may employ one or more of the following elements: Si, Zr, Bi, Sb, Ce, Cs, K, Mo.Type: GrantFiled: June 12, 2006Date of Patent: August 10, 2010Assignee: Milliken & CompanyInventors: Keith A.
