Patent ID: 8896521

Claim:
An apparatus comprising: a glass substrate having a first surface and a second surface opposite the first surface, the glass substrate including a plurality of first vias, each of the first vias extending from the first surface towards the second surface, each first via defined by an inner via surface of the glass substrate; a first electrode layer disposed over regions of the first surface of the glass substrate and disposed on the inner via surfaces in the first vias; a dielectric layer disposed on the first electrode layer including on portions of the first electrode layer in the first vias; and a second electrode layer disposed on the dielectric layer including on portions of the dielectric layer in the first vias, the dielectric layer electrically isolating the first electrode layer from the second electrode layer in each of the first vias; and wherein at least the portions of the first electrode layer, the portions of the dielectric layer, and the portions of the second electrode layer in the first vias form a capacitive structure having a capacitance.
