  • Patent number: 9040121
    Abstract: Vacuum deposited thin films of material are described to create an interface that non-preferentially interacts with different domains of an underlying block copolymer film. The non-preferential interface prevents formation of a wetting layer and influences the orientation of domains in the block copolymer. The purpose of the deposited polymer is to produce nanostructured features in a block copolymer film that can serve as lithographic patterns.

    Abstract: Provided are a polymer composition on a substrate and a surface modification method which is non-selective to substrate materials. Chemical vapor deposition polymerization is used to deposit a maleimide-functionalized poly-p-xylylene coating on a substrate. The substrate is readily available to perform a thiol-maleimide coupling reaction under mild conditions so as to modify the surface thereof. Furthermore, through a tailored thiol-terminal molecule, a designer surface can be created via thiol-maleimide coupling on a substrate, and the resulting surface can exhibit various desired biological functions for biotechnological applications. Therefore, this modification technique can be applied to biological fields extensively.

The approach is advantageous insofar as restrictions with respect to pot time no longer exist and, in addition, better features of the coating material are obtained, especially a high scratch-resistance.

  • Patent number: 7807267
    Abstract: The present invention relates to a method for modifying a porous film mainly having Si—O bonds wherein a thermal treatment is conducted without using a metal catalyst by bringing an organic silicon compound into contact with the porous film. The organic silicon compound includes one or more Si—X—Si bond unit (wherein X represents O, NR, CnH2n, or C6H4; R represents CmH2m+1 or C6H5; m is an integer between 1 and 6; and n is 1 or 2) and two or more Si-A bond units (wherein A represents H, OH, OCeH2e+1 or a halogen atom and can be the same or different within a single molecule; and e is an integer between 1 and 6). Since the porous film obtained by this method is excellent in the hydrophobic property and the mechanical strength, it can be used as an optically functional material or an electronically functional material. The porous film is especially useful as a semiconductor material, and can be preferably used as an interlayer insulating film in a semiconductor device.

  • Patent number: 7781016
    Abstract: Methods are disclosed of determining a fill level of a precursor in a bubbler. The bubbler is fluidicly coupled with a substrate processing chamber through a vapor-delivery system. The bubbler and vapor-delivery system are backfilled with a known dose of a backfill gas. A pressure and temperature of the backfill gas are determined, permitting a total volume for the backfill gas in the bubbler and vapor-delivery system to be determined by application of a gas law. The fill level of the precursor in the bubbler is determined as a difference between (1) a total volume of the bubbler and vapor-delivery system and (2) the determined total volume for the backfill gas.

  • Patent number: 7713573
    Abstract: The present invention relates generally to medical devices with therapy eluting components and methods for making same. More specifically, the invention relates to implantable medical devices having at least one porous layer, and methods for making such devices, and loading such devices with therapeutic agents. A mixture or alloy is placed on the surface of a medical device, then one component of the mixture or alloy is generally removed without generally removing the other components of the mixture or alloy. In some embodiments, a porous layer is adapted for bonding non-metallic coating, including drug eluting polymeric coatings. A porous layer may have a random pore structure or an oriented or directional grain porous structure. One embodiment of the invention relates to medical devices, including vascular stents, having at least one porous layer adapted to resist stenosis or cellular proliferation without requiring elution of therapeutic agents.
