  • Patent number: 9496355
    Abstract: Isolated conductive nanoparticles on a dielectric layer and methods of fabricating such isolated conductive nanoparticles provide charge storage units in electronic structures for use in a wide range of electronic devices and systems. The isolated conductive nanoparticles may be used as a floating gate in a flash memory. In an embodiment, conductive nanoparticles are deposited on a dielectric layer by a plasma-assisted deposition process such that each conductive nanoparticle is isolated from the other conductive nanoparticles to configure the conductive nanoparticles as charge storage elements.

  • Patent number: 9496491
    Abstract: A method of forming a metal chalcogenide material. The method comprises introducing a metal precursor and a chalcogenide precursor into a chamber, and reacting the metal precursor and the chalcogenide precursor to form a metal chalcogenide material on a substrate. The metal precursor is a carboxylate of an alkali metal, an alkaline earth metal, a transition metal, a post-transition metal, or a metalloid. The chalcogenide precursor is a hydride, alkyl, or aryl precursor of sulfur, selenium, or tellurium or a silylhydride, silylalkyl, or silylaryl precursor of sulfur, selenium, or tellurium. Methods of forming a memory cell including the metal chalcogenide material are also disclosed, as are memory cells including the metal chalcogenide material.

  • Publication number: 20150137333
    Abstract: Methods for depositing a material, such as a metal or a transition metal oxide, using an ALD (atomic layer deposition) process and resulting structures are disclosed. Such methods include treating a surface of a semiconductor structure periodically throughout the ALD process to regenerate a blocking material or to coat a blocking material that enables selective deposition of the material on a surface of a substrate. The surface treatment may reactivate a surface of the substrate toward the blocking material, may restore the blocking material after degradation occurs during the ALD process, and/or may coat the blocking material to prevent further degradation during the ALD process. For example, the surface treatment may be applied after performing one or more ALD cycles. Accordingly, the presently disclosed methods enable in situ restoration of blocking materials in ALD process that are generally incompatible with the blocking material and also enables selective deposition in recessed structures.
