Abstract:
PURPOSE:To enhance resolution and etching resistance by irradiating energy rays on a thin sensitive film formed on an optional substrate, patternwise passivating or activating it, and combining a chemical compd. with the remaining parts. CONSTITUTION:The thin photosensitive layer contg. a sensitive group causing chemical reaction on exposure to energy rays is formed on an optional substrate. This film is patternwise exposed to energy rays to passivate or activate the sensitive group, then a chemical substance of a straight chain siloxane molecule with Cl atoms on both terminals is selectively combined to the remaining parts to form a pattern. As the substrate, a hydrophilic substrate is used, and as the sensitive film, a straight chain hydrocarbon having a vinyl or cyano group on one terminal and a chlorosilane group on the other terminal.
Abstract:
PURPOSE:To form resist patterns with high precision on an organic thin film regardless of surface irregularity on a basic substrate by a method wherein a light sensitive LB film patterns containing Si are transferred to an organic thin film utilizing O2 plasma. CONSTITUTION:A semiconductor substrate 1 is coated with an organic thin film 2 and then light sensitive LB films 3 containing Si are laminated on the film 2 while LB film patterns 3' are formed by selectively polymerizing or decomposing the LB films 3 utilizing energy beams 4. The LB film patterns 3' comprising only a few layers but with high O2 resistant plasma etching property can well endure O2 plasma etching process in the basic organic thin film 2. Besides, the LB films laminated with monomolecular films may be formed evenly thick on overall surface regardless of minor irregularity in the thickness to form pattern with evenly high precision on overall surface. Through these procedures, the organic film patterns 2' may be utilized as etching resist to etch the substrate 1.

Abstract:
The invention relates to protein thin films and compositions for use in their preparation. In one aspect reverse micelles of protein are used to prepare homogeneous thin films. The process is useful for making thin films of water-soluble proteins which might otherwise be unstable at the air/water interface. In another aspect protein thin films are thermally stabilized whilst preserving the functional properties to produce an oriented Langmuir-Blodgett protein film. Another aspect provides a method for preparing protein thin films on non-planar substrates such as microparticles. Also, in another aspect, the invention provides for chemical functionalization and site-specific mutagenesis of proteins to provide ordered protein thin films.
