Composite reconstituted wafer structures
View Patent ↗A reconstituted electronic device comprising at least one die and at least one passive component. A functional material is incorporated in the substrate of the device to modify the electrical behavior of the passive component. The passive component may be formed in redistribution layers of the device. Composite functional materials may be used in the substrate to forms part of or all of the passive component. A metal carrier may form part of the substrate and part of the at least one passive component.
1. A reconstituted electronic device, comprising
a substrate in which at least one die and one piece of functional material are embedded, and
at least one metallic redistribution layer on a surface of the substrate, the at least one metallic redistribution layer defining an electrical component in an area at least partially within the area of the functional material when viewed in a plan view,
wherein the electrical component is an interdigitated metal oxide metal capacitor.
2. A reconstituted electronic device according to claim 1 , wherein the functional material is a ceramic.
