Patent number: 8968423Abstract: A technique for forming a cathode of a wet electrolytic capacitor is provided. The cathode contains a metal substrate having a roughened surface and a conductive coating that contains a substituted polythiophene. The degree of surface contact between the conductive coating and the roughened surface is enhanced in the present invention by selectively controlling the manner in which the conductive coating is formed. More particularly, the conductive coating is formed by applying a precursor solution to the roughened surface that includes both a precursor thiophene monomer and an oxidative catalyst. Contrary to techniques in which either the monomer or catalyst is applied separately and initially contacts the metal surface, the presence of the monomer and catalyst within the same solution allows polymer chains to grow immediately adjacent to the surface of the metal substrate and within the pits.Type: GrantFiled: July 28, 2011Date of Patent: March 3, 2015Assignee: AVX CorporationInventor: Martin Biler

Patent number: 8968467Abstract: Techniques for controlling resistivity in the formation of a silicon ingot from compensated feedstock silicon material prepares a compensated, upgraded metallurgical silicon feedstock for being melted to form a silicon melt. The compensated, upgraded metallurgical silicon feedstock provides semiconductor predominantly of a single type (p-type or n-type) for which the process assesses the concentrations of boron and phosphorus and adds a predetermined amount of boron, phosphorus, aluminum and/or gallium. The process further melts the silicon feedstock with the boron, phosphorus, aluminum and/or gallium to form a molten silicon solution from which to perform directional solidification and maintains the homogeneity of the resistivity of the silicon throughout the ingot. A balanced amount of phosphorus can be optionally added to the aluminum and/or gallium. Resistivity may also be measured repeatedly during ingot formation, and additional dopant may be added in response, either repeatedly or continuously.Type: GrantFiled: November 13, 2009Date of Patent: March 3, 2015Assignee: Silicor Materials Inc.Inventors: Fritz Kirscht, Marcin Walerysiak, Matthias Heuer, Anis Jouini, Kamel Ounadjela

Patent number: 8968468Abstract: When pulling and growing a single crystal from a raw material melt by the Czochralski method, a boundary between the single crystal and the raw material melt is imaged by an optical sensor, and also the weight of the single crystal is measured by a weight sensor, a diameter value of the single crystal is calculated on the basis of first measured values of the diameter of the single crystal derived from image data captured by the optical sensor and second measured values of the diameter of the single crystal derived from weight data captured by the weight sensor, and a pulling rate of the single crystal and the temperature of the raw material melt are adjusted on the basis of the calculated diameter value to thereby control the diameter of the single crystal, and thus it is possible to accurately measure the diameter of a growing single crystal.Type: GrantFiled: March 26, 2010Date of Patent: March 3, 2015Assignee: Sumco CorporationInventor: Ken Hamada

Patent number: 8968469Abstract: A structure including a substrate, an intermediate layer provided and formed directly onto the substrate, a transition region, and a group II-VI bulk crystal material provided and formed as an extension of the transition region. The transition region acts to change the structure from the underlying substrate to that of the bulk crystal. In a method of manufacture, a similar technique can be used for growing the transition region and the bulk crystal layer.Type: GrantFiled: October 11, 2010Date of Patent: March 3, 2015Assignee: Kromek LimitedInventors: Arnab Basu, Max Robinson, Ben Cantwell, Andy Brinkman

Patent number: 8968470Abstract: Disclosed herein are a graphite crucible for electromagnetic induction-based silicon melting and an apparatus for silicon melting/refining using the same, which performs a melting operation by a combination of indirect melting and direct melting. The crucible is formed of a graphite material and includes a cylindrical body having an open upper part through which a silicon raw material is charged into the crucible, and an outer wall surrounded by an induction coil, wherein a plurality of slits are vertically formed through the outer wall and an inner wall of the crucible such that an electromagnetic force created by an electric current flowing in the induction coil acts toward an inner center of the crucible to prevent a silicon melt from contacting the inner wall of the crucible.Type: GrantFiled: September 28, 2009Date of Patent: March 3, 2015Assignee: Korea Institute of Energy ResearchInventors: Bo Yun Jang, Young Soo Ahn, Joon Soo Kim, Sang Hyun Park, Dong Kook Kim, Gwon Jong Yu
