Method of manufacturing an integrated component with improved spatial occupation, and integrated component

An integrated component, comprising:

• a first wafer having first and second trenches defined in a top surface thereof;
• and
• a second wafer formed by a substrate and a structural layer on the substrate, the structural layer integrating an electromagnetic radiation detector overlying the second trench, the second wafer being coupled to the first wafer;
• a first cap coupled to the second wafer in a position overlying the electromagnetic radiation detector and serving to cooperate with the second wafer to define a first air-tight chamber for the electromagnetic radiation detector;
• a stator, a rotor, and a mobile mass integrated in the substrate of the second wafer, the stator and rotor forming a drive assembly for driving the mobile mass, the rotor overlying the first trench;
• and
• a second cap coupled to the second wafer in a position overlying the mobile mass and serving to cooperate with the second wafer to define a second air-tight chamber for the mobile mass.
