Patent number: 7763979Abstract: The dielectric constants of SiC and SiCN that are currently the subjects of much investigation are both 4.5 to 5 or so and that of SiOC, 2.8 to 3.0 or so.

The insulator material is annealed such that the low-k dielectric material undergoes a surface transformation to transform the arrangement of at least one hole into predetermined arrangement of at least one empty space below the surface of the insulator material. Other aspects are provided herein.Type: GrantFiled: August 31, 2004Date of Patent: June 23, 2009Assignee: Micron Technology, Inc.Inventors: Joseph E. Geusic, Paul A. Farrar, Arup Bhattacharyya

Patent number: 7550761Abstract: Systems and methodologies are provided for forming a diode component integral with a memory cell to facilitate programming arrays of memory cells created therefrom. Such a diode component can be part of a PN junction of memory cell having a passive and active layer with asymmetric semiconducting properties. Such an arrangement reduces a number of transistor-type voltage controls and associated power consumption, while enabling individual memory cell programming as part of a passive array. Moreover, the system provides for an efficient placement of memory cells on a wafer surface, and increases an amount of die space available for circuit design.Type: GrantFiled: December 26, 2006Date of Patent: June 23, 2009Assignee: Spansion LLCInventors: Juri H. Krieger, Stuart Spitzer

Patent number: 7544966Abstract: A three terminal electrical bistable device that includes a tri-layer composed of an electrically conductive mixed layer sandwiched between two layers of low conductivity organic material that is interposed between a top electrode and a bottom electrode. The conducting mixed layer serves as the middle electrode. The device includes two memory cells composed of electrode/organic layer/mixed layer, where the interfaces between the electrically conductive mixed layer and the low conductivity organic layer exhibit bistable behavior.Type: GrantFiled: December 1, 2004Date of Patent: June 9, 2009Assignee: The Regents of the University of CaliforniaInventors: Yang Yang, Liping Ma, Jun He

Patent number: 7531835Abstract: Organic FETs are produced having high mobilities in the accumulation mode and in the depletion mode. Significantly higher mobility is obtained from FETs in which RR-P3HT film is applied by dip-coating to a thickness of only about 20 ? to 1 ?m. It was found that the structural order of the semiconducting polymer at the interface between the semiconducting polymer and the SiO2 gate-insulator is important for achieving high carrier mobility. Heat-treatment under an inert atmosphere also was found to increase the on/off ratio of the FET.Type: GrantFiled: November 21, 2005Date of Patent: May 12, 2009Assignee: The Regents of the University of CaliforniaInventors: Alan J. Heeger, Daniel Moses, Guangming Wang, James S. Swensen

Patent number: RE41427Abstract: Hybrid crystalline organic-inorganic quantum confined systems are disclosed, which contain alternating layers of a bifunctional organic ligand and a II-VI semiconducting chalcogenide, wherein the semiconducting chalcogenide layers contain chalcogenides have the formula MQ, in which M is independently selected from II-VI semiconductor cationic species and Q is independently selected from S, Se and Te; and the bifunctional organic ligands of each organic ligand layer are bonded by a first functional group to an element M of an adjacent II-VI semiconducting chalcogenide layer and by a second functional group to an element M from the adjacent opposing II-VI semiconducting chalcogenide layer, so that the adjacent opposing II-VI semiconducting chalcogenide layers are linked by the bifunctional organic ligands of the organic ligand layers. Optical absorption experiments show that these systems produce a significant blue shift in their optical absorption edges, 1.2-1.5 eV, compared to a shift of 1.Type: GrantFiled: May 13, 2005Date of Patent: July 13, 2010Assignee: Rutgers, The State UniversityInventors: Jing Li, Xiaoying Huang
