Abstract:
1. An assembly comprising a piezoelectric resonator and a case, said case including a base part, on which said resonator is mounted, a wall extending from said base part so as to surround at least partially said resonator, and a cover fixed to said wall in such a way as to close said case, the base part and the wall being made of silicon and being separated by a dielectric layer, wherein the base part includes a main portion and at least two conductive vias, the conductive vias electrically connecting said piezoelectric resonator to an outside circuit through the base part, and each of the conductive vias being surrounded by a insulating lining so as to insulate said vias from the main portion, wherein said main portion is divided into two parts by an insulating partition in such a way that the two conductive vias are on different sides of said partition.
