Abstract
An apparatus is provided for forming a monomolecular film or a monomolecular layer built-up film on a substrate by spreading a group of monomolecular film-forming molecules on a liquid surface and contacting the substrate with the group of the monomolecular film-forming molecules. The apparatus comprises a frame for confining the spread liquid surface and structure for isolating and moving at least two different monomolecular layers on the spread liquid surface within the frame.
