Patent number: 8540892Abstract: High quantum yield InP nanocrystals are used in the bio-technology, bio-medical, and photovoltaic, specifically IV, III-V and III-VI nanocrystal technological applications. InP nanocrystals typically require post-generation HF treatment. Combining microwave methodologies with the presence of a fluorinated ionic liquid allows Fluorine ion etching without the hazards accompanying HF. Growing the InP nanocrystals in the presence of the ionic liquid allows in-situ etching to be achieved. The optimization of the PL QY is achieved by balancing growth and etching rates in the reaction.Type: GrantFiled: October 5, 2012Date of Patent: September 24, 2013Assignee: The Florida State University Research Foundation, Inc.Inventors: Geoffrey F.

Patent number: 8535547Abstract: A printed circuit board manufacturing system and a manufacturing method thereof are disclosed. A method of manufacturing printed circuit board, comprising: providing a substrate that comprises a pad and an insulation layer covering the pad; acquiring an image of the substrate; acquiring location information of the pad by analyzing the image of the substrate; forming a via hole by removing a part of the insulation layer that corresponds the location information of the pad; and forming a via by filling the via hole with a conductive material, provides improved process conformity, even if the substrate has partial or nonlinear deformation, by considering the location information of the pad in the via hole forming. The improved conformity may allow more flexibility to substrate design and more integrity for circuitries on printed circuit board.Type: GrantFiled: January 22, 2008Date of Patent: September 17, 2013Assignee: Samsung Electro-Mechanics Co., Ltd.Inventors: Chung-Woo Cho, Soon-Jin Cho, Byung-Bae Seo, Ki-Young Yoo, Seok-Hwan Ahn

Patent number: 8524606Abstract: Planarization methods include depositing a mask material on top of an overburden layer on a semiconductor wafer. The mask material is planarized to remove the mask material from up areas of the overburden layer to expose the overburden layer without removing the mask material from down areas. The exposed overburden layer is wet etched and leaves a thickness remaining over an underlying layer. Remaining portions of the mask layer and the exposed portions of the overburden layer are planarized to expose the underlying layer.Type: GrantFiled: January 25, 2011Date of Patent: September 3, 2013Assignees: International Business Machines Corporation, JSR CorporationInventors: Leslie Charns, John M.

Patent number: 8518283Abstract: The present invention relates to a plasma etching method in which a special area for detecting an end point needs not to be set and an equipment therefor. At an etching step of forming SF6 gas into plasma to etch an etching ground on a Si film, the step is configured by two steps of: a large-amount supply step of supplying a large amount of SF6 gas; and a small-amount supply step of supplying a small amount of SF6 gas. An end-point detecting processor 34 measures an emission intensity of Si or SiFx in the plasma at the small-amount supply step, and determines that an etching end point is reached when the measured emission intensity becomes equal to or less than a previously set reference value.Type: GrantFiled: July 27, 2007Date of Patent: August 27, 2013Assignee: SPP Technologies Co., Ltd.Inventors: Takashi Yamamoto, Masahiko Tanaka, Yoshiyuki Nozawa, Shoichi Murakami

Patent number: 8512581Abstract: Methods here disclosed provide for selectively coating the top surfaces or ridges of a 3-D substrate while avoiding liquid coating material wicking into micro cavities on 3-D substrates. The substrate includes holes formed in a three-dimensional substrate by forming a sacrificial layer on a template. The template includes a template substrate with posts and trenches between the posts. The steps include subsequently depositing a semiconductor layer and selectively etching the sacrificial layer. Then, the steps include releasing the semiconductor layer from the template and coating the 3-D substrate using a liquid transfer coating step for applying a liquid coating material to a surface of the 3-D substrate. The method may further include coating the 3-D substrate by selectively coating the top ridges or surfaces of the substrate.Type: GrantFiled: August 18, 2008Date of Patent: August 20, 2013Assignee: Solexel, Inc.Inventors: David Xuan-Qi Wang, Mehrdad M.
