Abstract:
An apparatus for producing a Langmuir-Blodgett film comprising:(a) a liquid bath having a spread region for spreading a material for forming a monomolecular film on a liquid surface, a compression region slanted downwards from the spread region for compressing the materials spread by the spread region to form a monomolecular film, and a level lamination region for receiving the monomolecular film from the compression region and for laminating, the monomolecular film on a substrate;(b) a first flow path for discharging a liquid which flows from the spread region of the liquid bath, to the outside of the liquid bath through the compression region and the lamination region;(c) a first valve in said first flow path for controlling the amount of the liquid discharged through the first flow path;(d) a second flow path for discharging the liquid, which flows from the spread region of the liquid bath to the boundary interface area between the compression region and the lamination region and thereafter to the outside of the bath;(e) a second valve in said second flow path for controlling the amount of the liquid discharged through the second flow path; and(f) means for switching between the first and second flow paths by operation of the first and second valves.
