An oscillator device includes: a structural layer extending over a first side of a semiconductor substrate; a semiconductor cap set on the structural layer; a coupling region extending between and hermetically sealing the structural layer and the cap and forming a cavity within the oscillator device; first and second conductive paths extending between the substrate and the structural layer; first and second conductive pads housed in the cavity and electrically coupled to first terminal portions of the first and second conductive paths by first and second connection regions, respectively, which extend through and are insulated from the structural layer; a piezoelectric resonator having first and second ends electrically coupled, respectively, to the first and second conductive pads, and extending in the cavity; and third and fourth conductive pads positioned outside the cavity and electrically coupled to second terminal portions of the first and second conductive paths.
