Claim 11:
12. A method of forming a semiconductor device, the method comprising:
forming a first plurality of redistribution layers on a first substrate, the first plurality of redistribution layers comprising a first plurality of conductive pads, the first plurality of conductive pads exposed on a top surface of the first plurality of redistribution layers;
forming an adhesive over the first plurality of redistribution layers;
singulating the first substrate, the first plurality of redistribution layers, and the adhesive into a plurality of local interconnect components, a first local interconnect component of the plurality of local interconnect components comprising:
a singulated portion of the first substrate;
a singulated portion of the first plurality of redistribution layers on the singulated portion of the first substrate;
a first conductive pad of the first plurality of conductive pads and a second conductive pad of the first plurality of conductive pads extending to a top surface of the singulated portion of the first plurality of redistribution layers; and
a singulated portion of the adhesive covering the singulated portion of the first plurality of redistribution layers;

attaching the first local interconnect component to a second substrate;
encapsulating the first local interconnect component with a first encapsulant;
removing a top portion of the first encapsulant and removing the singulated portion of the first substrate from the first local interconnect component;
forming a first redistribution structure over a first side of the first local interconnect component and the first encapsulant;
removing the first local interconnect component, the first encapsulant, and the first redistribution structure from the second substrate and attaching the first redistribution structure to a third substrate;
removing the singulated portion of the adhesive to expose the first conductive pad and the second conductive pad; and
forming a second redistribution structure over a second side of the first local interconnect component and the first encapsulant, the second side being opposite the first side, the second redistribution structure comprising a third conductive pad and a fourth conductive pad, the third conductive pad being bonded to the first conductive pad, the fourth conductive pad being bonded to the second conductive pad.
