Abstract
A process for producing a Langmuir-Blodgett (LB) film, comprising the steps of: developing a monomolecular film of a film forming molecule on the surface of water and transferring the monomolecular film on a substrate, wherein a film forming solution containing the film forming molecule is dropped on the surface of water while allowing a water stream directed to the substrate to act on the surface of water or allowing an air stream directed to the substrate to act on a position in the vicinity of the surface of water; a condensed film of the film forming molecule is rapidly formed upon dropping of the film forming solution by taking advantage of the action of the water stream or air stream; and, after or simultaneously with the formation of the condensed film, the condensed film is transferred onto the substrate. This process can prevent the inclusion of impurities, enabling an LB film to be produced using a small apparatus without using any large developing trough. Further, a hybrid LB film can be formed by changing the film forming molecule dropped on the surface of water in the course of the formation of the LB film.
