Abstract: An electronic component package comprising a substrate having at least one die-receiving cavity formed therein, the cavity being defined by a die-receiving surface and an inner sidewall having a terraced contour, the substrate having an exterior surface bordering the cavity perimeter, the inner sidewall extending between the die-receiving surface and the substrate exterior surface, and at least one capacitor positioned completely within the cavity and mounted to the terraced contour of the inner sidewall.

Abstract: A method is described for providing a body of first material and a body of second material in a chemical environment wherein the first material contains first constituents having a lower and higher oxidation state and wherein the second material contains constituents having an oxidation state of energy greater than lower oxidation state of the first constituent. The environment is further provided with first cations energetically disposed for receiving electrons from the first constituents but not energetically disposed for receiving electrons from the second constituents. Electrons transfer from the first constituents to the first cations which are transformed thereby into second cations of lower oxidation state resulting in first body releasing into the environment third cations which are cations of the first (lower) oxidation state of the first constituent.
