STRUCTURE EQUIPPED WITH ELECTRIC CONTACTS FORMED THROUGH SAID STRUCTURE SUBSTRATE AND METHOD FOR OBTAINING SAID STRUCTURE

摘要

The invention concerns a structure to be equipped with at least one electric contact formed in a layer (24), on the front surface side thereof. Said layer is formed on a substrate (20) which is bored with at least one hole (28) to expose the layer rear surface. The contact (32) is formed thereon opposite the hole, in a cavity overhung by the hole edge closest to the first layer, said overhang enabling to insulate electrically the substrate contact. The invention is applicable to accelerometers, pressure sensors and actuators.
