Abstract:
A film formation system and a film formation method are disclosed. The film formation method includes the following steps performed in the film formation system that includes a container containing liquid, a liquid draining device for draining the liquid, a ring-shaped component installed in the container, and a carrying component installed in the liquid in the container for carrying at least a substrate: enabling the carrying component in the liquid and enabling the ring-shaped component to float on the liquid; when a film layer that is composed of nano-spheres is formed on the liquid, locating the film layer in a ring of the ring-shaped component; and removing the liquid, allowing the film layer to move downward in accordance with the ring-shaped component and be formed on the substrate, thereby preventing the nano-spheres from contacting an inner wall of the container and bursting, through the installation of the ring-shaped component.
Abstract:
A method and apparatus for continuously forming and depositing a layer of monomolecular amphiphilic molecules on a substrate, which include the continuous or intermittent removal of unused film after a substrate dipping. The amount of "dwell time" in which the film resides on the surface of the support media is controlled. A rotatable barrier provides a movable "film front" to achieve repeatable film pressures, consistencies and viscosities of high precision and accuracy.
Abstract:
An ultra-thin, self-assembling molecular film has ordered amphiphilic molecules that are oriented relative to one another in two directions. The improved method of the present application makes it possible to form the film in a continuous fashion with the ordered molecules arranged in oriented crystals.
Abstract:
An apparatus for forming thin organic films includes a plurality of water tanks each containing water. Monomolecular films of different amphiphatic organic molecules are developed on the surfaces of the liquid in water tanks, respectively. A work is dipped into and raised out of a desired water tank, by a driving device, in a direction substantially perpendicular to the liquid surface, so that the monomolecular film in the water tank is adhered on a work surface. The work is transported by a transporting device to a position above another water tank, through an area lying above the water tanks. Then, the work is dipped into and raised out of the other water tank, by the driving device, in a direction substantially perpendicular to the monomolecular film, so that another monomolecular film is adhered on the monomolecular film already formed on the work surface.
Abstract:
Disclosed is a method and apparatus for continuously forming and depositing a layer of monomolecular amphiphilic molecules on a substrate. The present invention includes an apparatus and method for transferring and compressing an uncompressed molecular layer from one liquid surface region in a tank to another adjacent liquid surface region by using non-moving or static mechanical components which do not come into direct contact with the monomolecular layer. The present invention includes a method and apparatus which permit the continuous and simultaneous draining and replenishing of the liquid in the tank while maintaining the liquid surface level constant. The continuous replacement of the liquid in the tank with clean liquid reduces the level of contamination of the liquid in the tank. In addition, the level, as well as the type of contamination of the liquid, does not vary significantly with time. This aspect of the present invention reduces the variation in the quality and characteristics of the monolayers that are produced in the tank and are deposited onto the substrate. Also by reducing the need to replace the liquid in the tank periodically, the present invention increases the efficiency of the process.
Abstract:
An apparatus for forming a monomolecular film or a monomolecular built-up film on a substrate, which comprises a tank, a frame for dividing a liquid surface in the tank and a support for moving the substrate horizontally in the liquid without disordering the liquid surface within the frame which contains the film.
Abstract:
Tank for depositing a monomolecular film. It comprises a tank having walls and a base and containing a liquid, a barrier defining two areas on the surface of the liquid, means for displacing the barrier on the surface of the liquid, at least one substrate and means for displacing the substrate. The level of the liquid is below the horizontal rim of the tank. The barrier has a break at each of its ends and rests on the edges of the tank. The break defines a narrower portion partly submerged in the liquid. Sealing means are provided between the faces of the narrower portion and the facing walls.
Abstract:
The monomolecular layer is first formed from a solution of amphiphilic molecules by introduction of the solution on a liquid surface which is divided into at least two compartments by at least one rotatable and partly immersed horizontal member. The solvent is then removed and the horizontal member is driven in rotation so as to apply a predetermined pressure to said layer as this latter is transferred from one compartment to the next, the layer being finally deposited on a substrate.This a division of application Ser.
