A polymer layer is deposited on a surface of a support, said surface comprising a flat main part and at least one recessed zone with respect to the flat main part. The polymer layer is achieved by at least the following successive steps:

Method for depositing a polymer layer on a surface of a support comprising at least a recessed zone

A method producing conductive rods localized on conductive blocks of an electronic component.

Microelectronic interconnect device comprising localised conductive pins

This invention relates to a process for manufacturing an anisotropic conducting film comprising a layer of electrically insulating material and conducting through inserts, the process including the following steps: a) formation on a substrate of at least one layer of material with through holes, the layer being called the perforated layer, b) filling of the through holes to form conducting inserts. The process also includes production of a mask partially covering a first end of the conducting inserts and etching of the unmasked part of the ends of the conducting inserts so as to obtain conducting inserts with pointed ends. The invention is applicable to the formation of components (chips, integrated circuits) with a high interconnections density.
