Abstract:
1. A method comprising: attaching a first and a second die to a carrier, the first and the second die each having interconnect areas on a side opposite the carrier; attaching a dielectric sheet over the interconnect areas of the first and the second die, the dielectric sheet having a polished surface facing the dies, and being stable to 600° C.; forming conductive vias in the dielectric sheet over the interconnect areas after attaching the dielectric sheet to connect with pads of the interconnect areas; depositing build-up layers over the dielectric sheet, the build-up layers including routing to connect pads of the first die interconnect area to pads of the second die interconnect area through the conductive vias; and packaging the dies, the dielectric sheet, and the build-up layers by mounting the dies to a package substrate through the build-up layers.
