The invention relates to a microlithographic process for producing circuits using organic, conductive films sensitive to electromagnetic radiation and to charged particles. This process for producing electricity conducting zones on a substrate consists of depositing on said substrate a coating of an electricity conducting, organic compound, such as alkyl pyridinium-tetracyanoquinodimethane and then irradiating certain locations (2,3) of the coating by means of charged particles and/or electromagnetic radiation, so that the irradiated locations become insulating and that on the organic compound coating the electricity conducting zones (1) are directly formed at the desired locations.

Microlithographic process for producing circuits using conductive

Electrically-conducting films comprising at least one monomolecular layer of an organic charge transfer complex and their production process. These films comprise at least one monomolecular layer of an organic charge transfer complex having at least one electron acceptor group and at least one electron donor group, the electron acceptor and/or donor group having at least one hydrocarbon chain with 16 to 30 carbon atoms and the electron acceptor and/or donor groups being organized in such a way that two adjacent groups of the same type, namely electron donors or electron acceptors, can be sufficiently coupled in the plane of the layer to exchange an electron and ensure an electrical conduction in said plane. The charge transfer complex can be an alkyl pyridinium-tetracyanoquinodimethane.

Electrically conducting films comprising at least one monomolecular

Process for producing a film having at least one monomolecular layer of non-amphiphilic molecules. This process comprises the following stages:

Process for producing a thin film having at least one monomolecular

The monomolecular layer is first formed from a solution of amphiphilic molecules by introduction of the solution on a liquid surface which is divided into at least two compartments by at least one rotatable and partly immersed horizontal member. The solvent is then removed and the horizontal member is driven in rotation so as to apply a predetermined pressure to said layer as this latter is transferred from one compartment to the next, the layer being finally deposited on a substrate.
