A capacitive structure is made with thin film capacitor plates substantially surrounding an opening cavity for accommodating a chip. The capacitive structure includes at least one capacitor and is mounted around the periphery of a ball grid array “BGA” having a flip chip in the opening. The capacitive structure provides a high capacitance with a low parasitic inductance.
