Abstract
This review paper gives an overview of Langmuir-Blodgett (LB) films in relation to their possible applications in electronics. LB films are ultrathin organic films with controllable structures of molecular dimensions. The preparation techiques are outlined in order to understand the characteristic features of LB films. They involve the manipulation of monomolecular sheets (monolayers) formed on a water-air interface and the transfer of them onto a solid substrate as the fundamental techniques, and the fabrication of superstructures, the utilization of composite layers, the monomolecular sweeping technique and the manipulation of monolayer packages as the advanced techniques. Examples are shown of versatile investigations aiming at the application of LB films in electronics : as ultrathin insulators in microelectronic devices such as Josephson junctions and FET's, for microlithograpy such as high-resolution electron-beam resist films, and as the active materials associated with specific functions such as non-linear optical properties and semiconductive or metallic conductivity.
