Abstract:
1. A method of repairing an integrated electronic circuit, comprising the formation of an electrical isolation between two conducting parts of the circuit that are located at respective places of the circuit, a volume having been errantly hollowed out for the purpose of forming both at least one of the conducting parts and an electrical connection that connects the two places, the method comprising the following steps: a) formation of a mask on the circuit having an aperture that reveals a portion of the errantly hollowed out volume; b) deposition of an electrically insulating material on that portion revealed by the mask, so as to at least partly fill the errantly hollowed out volume; and c) removal of the mask, so as to leave the errantly hollowed out volume at least partly filled with insulating material; and d) depositing an electrically conducting material in a non-filled portion of the errantly hollowed out volume so as to form at least one of the two conducting parts electrically insulated from the other of the conducting parts by the deposited insulating material.
