Publication number: 20070001151Abstract: A new class of materials for use in electric and electroluminescent devices having one or more phosphine oxide moieties bonded by single bonds to two outer groups. In embodiments having two or more phosphine oxide moieties, the two or more phosphine oxide moieties are further joined by a bridging group. By selecting appropriate bridging and outer groups, the new class of materials of the present invention enables designers to “tune” the electrical and electroluminescent characteristics of the materials. The phosphine oxide moiety restricts electron conjugation between the bridging and outer groups, isolating the bridging and outer groups from each other, and allowing the photophysical properties of the bridging and outer groups to be maintained in the molecule. The lowest energy component (bridging group or particular outer group) thus defines the triplet state, highest occupied molecular orbital and lowest unoccupied molecular energies for the entire molecule.Type: ApplicationFiled: January 12, 2005Publication date: January 4, 2007Inventors: Linda Sapochak, Paul Burrows, Asanga Padmaperuma, Murukkuwadura De Silva, Byron Bennett

Publication number: 20070001195Abstract: An indium phosphide based double hetero junction bipolar transistor with an increased collector-base breakdown voltage and a reduced operational knee voltage is provided by manipulating the conductivity in the collector region. The collector is formed using layers of different conductivities, with a region of the collector relatively close to the base being unintentionally or low doped. A voltage drop across the unintentionally doped region reduces the maximum value of the electric field and the velocity of carriers injected into the collector region at the base-collector junction. The conductivity throughout the collector region may be graded such that the highest conductivity occurs near the sub-collector and lowest conductivity occurs near the base region.Type: ApplicationFiled: September 8, 2006Publication date: January 4, 2007Inventors: Shyh-Chiang Shen, David Caruth, Milton Feng

Publication number: 20070001196Abstract: A layout capable of placing a circuit constituted by a plurality of transistors in a small-with region is automatically formed. A search section inputs data on a circuit and makes a search for a set of routes formed so that passage through any one of the transistors occurs only one time and so that the combination of routes in one set can cover the entire circuit network. An extraction section extracts a set of routes having the smallest number of routes in sets of route found by searching. A width determination section determines the layout width from the widths of source and drain electrodes of each transistor, the width of the region between the source and drain electrodes, the width of the region between some of the adjacent pairs of the transistors not combined into a common electrode, the number of transistors, and the smallest number of routes.Type: ApplicationFiled: September 8, 2006Publication date: January 4, 2007Applicant: NEC CORPORATIONInventor: Yoshihiro Nonaka
