Abstract:
A method and apparatus are disclosed for forming thin films of chemical compounds utilized in integrated circuits. The method includes steps of forming a precursor liquid comprising a chemical compound in a solvent, providing a substrate within a vacuum deposition chamber, producing a mist of the precursor liquid, and flowing the mist into the deposition chamber while maintaining the chamber at ambient temperature to deposit a layer of the precursor liquid on the substrate. The liquid is dried to form a thin film of a solid material on the substrate, then the integrated circuit is completed to include at least a portion of the film of solid material in a component of the integrated circuit.

A method for depositing an aqueous coating composition onto an ink layer or uninked surface in a printing process comprising (1) depositing a first layer of the ink onto a surface to be coated, (2) drying said ink layer, (3) determining a desired viscosity of an aqueous coating composition to be deposited onto said ink layer or said surface, said composition comprising (a) about 15-85% by weight of a film-forming polymer, said film forming polymer comprising 10-90% by weight of a high molecular weight polymer of an average molecular weight of about 30,000 to about 5,000,000 and 10-90% by weight of a low molecular weight polymer of average molecular weight of about 100 to about 20,000, (b) an amount of wetting agent effective to substantially eliminate levelling problems after deposition caused by surface tension, and (c) the remainder comprising a mixture of water and optionally a volatile organic solvent. (4) determining the temperature above or below ambient temperature at which said composition attains the viscosity previously determined, (5) maintaining the desired viscosity of said composition at the temperature determined earlier and (6) depositing the aqueous coating composition at the determined temperature onto said ink layer or said surface.
Abstract:
A method of producing a particulate-solid-bearing air-permeable sheet of material of other than woven and knitted material selected from non-woven fabrics and open cell foam materials includes the following steps: entraining a particulate solid in a gaseous carrier in the substantial absence of fibrous material; disposing one face of a preformed air-permeable sheet material, which material has a density at or below 0.25 g/cm.sup.3, in the path of a stream of the gaseous carrier and entrained particulate solid, whilst maintaining a pressure drop across the thickness of the preformed air-permeable sheet material from the one face to the other face of the air-permeable sheet material, whereby to entrap some or all of the entrained particulate solid on or on and in the air-permeable material; and fixing the retained particulate solid on or on and in the air-permeable material with a binder. The mean pore size of the preformed sheet material is greater than the mean particle size of the particulate solid.
Abstract:
An assembly of an article and a polyimide is prepared. The assembly resists dimensional change, delamination, or debonding when exposed to changes in temperature. An article is provided. A soluble polyimide resin solution having a low coefficient of thermal expansion (CTE) was prepared by dissolving the polyimide in solvent and adding a metal ion-containing additive to the solution. Examples of this additive are: Ho(OOCCH.sub.3).sub.3, Er(NPPA).sub.3, TmCl.sub.3, and Er(C.sub.5 H.sub.7 O.sub.2).sub.3. The soluble polyimide resin is combined with the article to form the assembly.

Abstract:
The present invention relates to a method for forming a uniform, extremely thin film on the surface of plastics molded articles, films, sheets, synthetic paper, fibers, metal, and other objects, the film containing an anti-static agent, anti-fogging agent, anti-corrosive agent, mildewproofing agent, and the like. According to the method of the present invention, a homogenous solution or emulsion is prepared by dissolving a surfactant and agents in a solvent such as water with the aid of ultrasonic waves, and the solution is made into aerosol of fine particles by means of cavitation. The aerosol is brought into contact with an object, whereby the fine particles of aerosol are deposited on the object and a thin film of the solution is formed on the surface of the object due to the difference in surface tension between the surfactant and the object. After evaporation of the solvent, the agents are left on the surface of the object in the form of an extremely thin film. The present invention also relates to apparatuses for producing such aerosol, selecting aerosol particles, and bringing the aerosol into contact with the surface of an object.
