  • Publication number: 20030186468
    Abstract: Tunnel-junction structures are fabricated by any of a set of related methods that form two or more tunnel junctions simultaneously. The fabrication methods disclosed are compatible with conventional CMOS fabrication practices, including both single damascene and dual damascene processes. The simultaneously formed tunnel junctions may have different areas. In some embodiments, tub-well structures are formed with sloped sidewalls. In some embodiments, an oxide-metal-oxide film stack on the sidewall of a tub-well is etched to form the tunnel junctions. Memory circuits, other integrated circuit structures, substrates carrying microelectronics, and other electronic devices made by the methods are disclosed.

  • Patent number: 6410776
    Abstract: The invention relates to a process for the preparation of resols by reacting phenolic compounds with aldehydes with catalysis by metal salts whose cation can easily be precipitated as low-solubility salts in industrial processes. In this process, a dispersant is added to the reaction mixture comprising phenolic compound, aldehyde and metal salt before, during or after the condensation reaction, and a complexing agent is admixed after the condensation reaction is complete and after the dispersant has been admixed. The resultant resins are transparent even after neutralization using sulphuric acid.
