Abstract:
1. An integrated circuit package comprising: a plurality of stacked layers of a cured, photo-imageable epoxy that were deposited sequentially, wherein at least some of the epoxy layers were patterned, the plurality of epoxy layers including a first patterned epoxy layer, a second patterned epoxy layer, a third patterned epoxy layer, a fourth patterned epoxy layer and a fifth epoxy layer, the first patterned epoxy layer including a first cavity; a plurality of integrated circuits that include a first integrated circuit and a second integrated circuit, the first integrated circuit being positioned within the first cavity, the second patterned epoxy layer being formed on the first patterned epoxy layer and the first integrated circuit; a plurality of interconnect layers, including a first interconnect layer and a second interconnect layer, the first interconnect layer including a plurality of interconnect traces, the first interconnect layer formed on the second patterned epoxy layer and embedded in the second patterned epoxy layer, the first interconnect layer being electrically coupled through a via with the active surface of the first integrated circuit, wherein: a thermal pipe made of a thermally conductive material, the thermal pipe being embedded in at least one associated epoxy layer, the thermal pipe bending such that a first portion of the thermal pipe extends in a first direction and a second portion of the thermal pipe extends in a second direction substantially different from the first direction, the first portion of the thermal pipe being embedded in one of the epoxy layers and the long axis of the first portion of the thermal pipe extending substantially parallel to the one of the epoxy layers, the second portion of the thermal pipe being embedded in another one of the epoxy layers and the long axis of the second portion of the thermal pipe extending substantially perpendicular to the another one of the epoxy layers, wherein the thermal pipe thermally couples one of the integrated circuits with at least one exterior surface of the integrated circuit package; a component selected from a group consisting of an I/O pad that is exposed on the exterior of the integrated circuit package, an integrated circuit having an active surface that is covered by one of the epoxy layers and that is positioned in one of the patterned epoxy layers, and an electrical device that is embedded in one of the patterned epoxy layers, wherein one of the integrated circuits is electrically coupled with the component through one of the interconnect layers; and a multiplicity of external package contacts formed over the fifth epoxy layer, one of the integrated circuits being electrically connected to one of the external package contacts at least in part through one of the interconnect layers.
