Abstract
The invention relates to a process for manufacturing a sensor with a metal electrode in an MOS structure. During the MOS process, a sensing region with a structure for the metal electrode is formed, this structure being made of a material having predetermined adhesion properties for metals, the sensing region being uncovered by etching the passivating layer, and a metallization of the surface of the MOS structure being carried out in which the metal layer adheres only to the structure for the metal electrode.
