TRENCH CAPACITOR COMPONENT WITH REDUCED EQUIVALENT SERIES RESISTANCE AND EQUIVALENT SERIES INDUCTANCE

Abstract:

Certain aspects of the present disclosure generally relate to a capacitive element. One example capacitive element generally includes a substrate, a plurality of trench capacitors, an electrically conductive via, a first electrically conductive contact, and a second electrically conductive contact. The trench capacitors intersect the substrate. The electrically conductive via intersects the substrate and is disposed adjacent to at least one of the trench capacitors. The first electrically conductive contact is disposed above the substrate, and the second electrically conductive contact is disposed below the substrate and electrically coupled to the plurality of trench capacitors through the electrically conductive via.
