摘要:
A vapor delivery apparatus for providing a precursor vapor for a vapor deposition process includes a precursor container for holding a liquid or solid precursor. A first temperature control assembly maintains the precursor container at a first temperature to generate a vapor precursor from the liquid or solid precursor. An isolation valve is coupled to the precursor container, and a specific quantity of the vapor precursor is accumulated in an expansion volume. A fill valve, which is coupled to each of the isolation valve and the expansion volume, controls the flow of the vapor precursor from the precursor container into the expansion volume. A second temperature control assembly maintains the isolation valve at a second temperature greater than the first temperature.
摘要:
We have developed an improved vapor-phase deposition method and apparatus for the application of films / coatings on substrates. The method provides for the addition of a precise amount of each of the reactants to be consumed in a single reaction step of the coating formation process. In addition to the control over the amount of reactants added to the process chamber, the present invention requires precise control over the total pressure (which is less than atmospheric pressure) in the process chamber, the partial vapor pressure of each vaporous component present in the process chamber, the substrate temperature, and typically the temperature of a major processing surface within said process chamber. Control over this combination of variables determines a number of the characteristics of a film/coating or multi-layered film/coating formed using the method. By varying these process parameters, the roughness and the thickness of the films/coatings produced can be controlled.

We have developed an improved vapor-phase deposition method and apparatus for the application of organic films /coatings containing a variety of functional groups on substrates. Most substrates can be coated using the method of the invention. The substrate surface is halogenated using a vaporous halogen-containing compound, followed by a reaction with at least one organic molecule containing at least one nucleophilic functional group Capable of reacting with a halogenated substrate surface. The halogenation of the substrate surface and the subsequent reaction with the organic molecule nucleophilic functional group are carried out in the same process chamber in a manner such that the halogenated substrate surface does not lose its functionality prior to reaction with the nucleophilic functional group(s) on the organic molecule. Typically the process chamber is operated under a pressure ranging from about I nmTorr to about 10 Torr.

Oxide coatings providing hydrophilicity or oxide / polyethylene glycol coatings providing hydrophilicity can be deposited by the present method, over the interior surfaces of small wells in a plastic micro-plate or within the interior of lumens or other conduits in order to increase the hydrophilicity on the coated surface.
摘要:
A method of providing a biocompatible PEG-comprising coating on a substrate, without the use of an underlying adhesion layer. The coating is vapor deposited onto the substrate from a precursor which includes a PEG-derived moiety and an amino silane- containing functional group which reacts with the substrate. The substrate may be metal or plastic, where plastic excludes polyimide and polycarbonate. The substrate may be plasma treated prior to deposition of the PEG-comprising coating.
