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.
