  • Patent number: 9570343
    Abstract: The present invention is a new formulation and process for treating TiN semiconductor devices having a high aspect ratio structure formed thereon. The new composition is designed to be used in the chip making process between cleaning a wet etched memory device and its final rinse/drying process. It is intended to include the treatment in order to prevent collapse of the high aspect ratio TiN structure found on the semiconductor device.
    Type: Grant

  • Patent number: 8759465
    Abstract: A class of bioinspired, cross linking polymers, created by working catechol functionalities into the backbone of a bulk polymer, is disclosed. Varied cross linking groups may be incorporated into different polymer backbones, and subsequently reacted with an array of reagents. An adhesive composition comprising a copolymer, the copolymer comprising pendant dihydroxyphenyl groups; and a crosslinking agent selected from the group consisting of, for example, oxidants, enzymes, metals, and light. A method of preparing an adhesive composition comprising copolymerizing a first monomer comprising pendant dihydroxy-protected dihydroxyphenyl groups; deprotecting the dihydroxy-protected dihydroxyphenyl groups; crosslinking the dihydroxyphenyl groups with a crosslinking agent.

  • Patent number: 6838404
    Abstract: A method of making a superconducting structure includes depositing a metal alkoxide on a surface of a metal and hydrolyzing the metal alkoxide on the surface to form a pinhole-free film. The metal is a superconductor. The metal alkoxide may be a compound of formula (I): M4(OPrn)16??(I); where M is zirconium or hafnium, and the purity of the compound is at least 97% as measured by NMR spectroscopy.
