  • Memory cell containing copolymer containing diarylacetylene portion
    Patent number: 7777218
    Abstract: An organic memory cell containing an organic semiconductor layer containing a copolymer is disclosed. The copolymer contains a diarylacetylene portion and at least one of an arylacetylene portion and a heterocyclic acetylene portion. The copolymer may be a random copolymer, an alternating copolymer, a random block copolymer, or a block copolymer. Methods of making an organic memory devices/cells containing the copolymer, methods of using the organic memory devices/cells, and devices such as computers containing the organic memory devices/cells are also disclosed.
    Type: Grant

    Date of Patent: August 17, 2010
    Assignee: Spansion LLC
    Inventors: William G. Leonard, Richard P. Kingsborough, Igor Sokolik
  • System and method for processing an organic memory cell
    Patent number: 7632706
    Abstract: A system and method are disclosed for processing an organic memory cell. An exemplary system can employ an enclosed processing chamber, a passive layer formation component operative to form a passive layer on a first electrode, and an organic semiconductor layer formation component operative to form an organic semiconductor layer on the passive layer. A wafer substrate is not needed to transfer from a passive layer formation system to an organic semiconductor layer formation system. The passive layer is not exposed to air after formation of the passive layer and before formation of the organic semiconductor layer. As a result, conductive impurities caused by the exposure to air do not occur in the thin film layer, thus improving productivity, quality, and reliability of organic memory devices. The system can further employ a second electrode formation component operative to form a second electrode on the organic semiconductor layer.
