DIELECTRIC SUBSTRATE WITH REDUCED AND STABILIZED SURFACE ELECTRICAL CONDUCTIVITY, PROCESS FOR ITS MANUFACTURE, AND USE OF THE SUBSTRATE

摘要

In order to reduce and stabilize the electrical conductivity of surfaces of crystalline, polycrystalline or amorphous structure in such a way that the reduction and stabilisation is permanent and not affected by solvents or temperature changes, it is proposed that the surface of the substrate is cleaned chemically and brought into contact with chlorotrimethylsilane ((CH3)3ClSi) dissolved in at least one solvent, preferably a low chlorinated hydrocarbon (e.g. chloroform or dichloromethane), and the solvent and the gaseous substances produced by the chemical reaction are allowed to evaporate off. The valencies involved in the chemical reactions at the surface of the substrate are saturated after passivation with (CH3)3Si radicals.
