The hydrophilic surface is exposed to a fluid having a mixture of molecules which can self-assemble on the hydrophilic surface and hydrophobic molecules for a sufficient length of time so that the molecules which can self-assemble on the hydrophilic surface form a complete self-assembled monolayer. In a particular embodiment octadecylphosphonic acid (OPA) molecules have been self-assembled on oxidized substrates including but not limited to mica, silicon, sapphire, quartz and aluminum by spin-coating a solution containing the octadecylphosphonic acid (OPA) molecules and hydrophobic molecules such as chloroform or trichloroethylene under a controlled relative humidity. Control of the morphology of OPA SAMs is affected by adjusting humidity and the duration of spin-coating. Atomic force microscopy revealed that relative humidity has a profound influence on the morphology of the OPA SAMs formed.

  • Patent number: 7226637
    Abstract: An information layer for an optical information storage medium is formed in a centrifuge. A photopolymerizable composition is applied to a solid base having a relief pattern, and a flexible, transparent film layer is applied on top of the composition. The three are spun in a centrifuge to cause a thin, even distribution of the photopolymerizable composition, which is photopolymerized. The resulting replica is separated from the relief pattern and has a fluorescent material applied thereto. Alternatively, the replica has a non-fluorescent material applied thereto, and the non-fluorescent material is made fluorescent through diffusion. Multiple information layers thus formed can be glued together to form a multilayer optical information storage medium.

  • Patent number: 7211293
    Abstract: A closed-loop system and process is used for applying fire retardant chemicals to fibers. Fibers are preferably positioned in a vessel such as a dye machine which circulates the fire retardant chemicals. After absorption of the fire retardant composition, non-absorbed fire retardant chemicals are recovered and re-used on subsequent batches of fibers. Recovery can be achieved by directing the non-absorbed fire retardant composition into a second dye machine containing additional fibers, or by extracting the fire retardant composition by centrifugation or other means, or by a combination of the two processes. The process is environmentally friendly, and allows for higher throughput on impregnating fibers with fire retardant chemicals.

  • Patent number: 7211297
    Abstract: An fountain applicator for applying coating liquid onto a web of paper carried past the applicator, has a coating liquid flow path that includes a curved surface along which a sheet of the coating liquid is flowed to subject the sheet to centrifugal force to cause air entrained in the coating liquid to move away from one side of the sheet that is toward the curved surface, so that the one side is relatively free of entrained air. After being flowed along the curved surface, the sheet of coating liquid is directed toward the web in a free standing jet curtain of coating liquid, to contact the web surface primarily with the one relatively air-free side of the coating liquid sheet to decrease the occurrence of skip coating on the web surface, especially when the web is traveling past the applicator at high speeds. The coating is applied in excess onto the web surface and is metered and leveled to a desired coat weight by a downstream doctor.

  • Patent number: 7205025
    Abstract: In drying a coating liquid such as a resist applied to a substrate under reduced pressure, a coating film in a peripheral portion tends to lose good shape regardless of duration of a drying period, and it is difficult to set an appropriate exhaust flow rate. After the substrate is loaded in an airtight container, a pressure is reduced from atmospheric pressure to a pressure slightly higher than the vapor pressure of a solvent, for example. Then, the solvent actively evaporates from the coating liquid. Here, evacuation is performed initially based on a first flow rate set value Q1, and thereafter, it is performed based on a second flow rate set value larger than Q1. Rounding of the surface in the peripheral portion is corrected by evacuation based on Q1, and more active evaporation of a solvent component is attained by switching to Q2.

  • Patent number: 7205024
    Abstract: Prior to transfer of an wafer W, a mixed gas is being generated and exhausted, thereby fluctuation of concentration and temperature of a solvent component at the beginning of gas introduction into a chamber 3 is suppressed. A step of gelling after the wafer W is carried into an aging unit is divided into several steps. Until a temperature of the wafer W reaches a predetermined treatment temperature, an average concentration of the solvent component in a mixed gas is gradually raised relative to the temperature of the wafer W. Thereby, immediately after the wafer W is transferred into a sealed chamber, the gas of the solvent component is prevented from condensing.

  • Patent number: 7199062
    Abstract: A preferred embodiment of the invention provides a method of spin coating a liquid, such as a resist, onto a surface of a substrate. An embodiment of the invention comprises dispensing a liquid onto the surface; spinning the substrate at a first rotational velocity at least until the liquid forms a substantially uniform film on the surface of the substrate; and spinning the substrate at a second rotational velocity in an opposite direction at least until the liquid reforms a substantially uniform film on the surface of the substrate. Other embodiments include a first rotational acceleration for accelerating the substrate to the first rotational velocity, and a second rotational acceleration for accelerating the substrate to the second rotational velocity. Preferably, the second rotational acceleration is much larger than the first rotational acceleration. Still other embodiments include repeating the first velocity, second velocity sequence one or more times.

  • Patent number: 7191508
    Abstract: A method for manufacturing thin-film magnetic head sliders is disclosed. Initially, an elastic layer, which may be made of poly-dimethyl siloxane (PDMS), is spun on a wafer and is thermally cured. Then, a resist layer is spun on the elastic layer. Both the resist layer and the elastic layer are subsequently peeled off together from the wafer. Next, the peeled resist layer/elastic layer is applied onto a group of magnetic heads with the resist layer in direct contact with the magnetic heads. Finally, the elastic layer is peeled off from the resist layer such that the resist layer remains attaching to the magnetic heads.

  • Patent number: 7189428
    Abstract: A method for making a thin-film electrode, either an anode or a cathode, by preparing a precursor solution using an alkoxide reactant, depositing multiple thin film layers with each layer approximately 500–1000 ? in thickness, and heating the layers to above 600° C. to achieve a material with electrochemical properties suitable for use in a thin film battery. The preparation of the anode precursor solution uses Sn(OCH2C(CH3)3)2 dissolved in a solvent in the presence of HO2CCH3 and the cathode precursor solution is formed by dissolving a mixture of (Li(OCH2C(CH3)3))8 and Co(O2CCH3).H2O in at least one polar solvent.

  • Patent number: 7179504
    Abstract: The present invention relates to a processing method for processing a substrate, and comprises a step of coating a coating solution on a surface of the substrate while relatively moving a coating solution discharge nozzle and the substrate and discharging the coating solution from the nozzle onto the substrate. Thereafter, the substrate is exposed to a solvent atmosphere of the coating solution or the pressure is temporarily applied thereto in a container. Thereafter, the pressure inside the container in which the substrate is housed is reduced to dry the coating solution on the substrate. According to the present invention, it is possible to narrow the so-called edge cutting width, which is at a periphery part of the substrate and is not commercialized, and to maintain an in-plane uniformity of the coating film.
