Abstract:
1. A method of fabricating a microelectronic assembly, comprising: processing a first subassembly such that extremities of electrically conductive first connectors of the first subassembly project into a temporary layer, the first connectors extending in a direction away from a first support element of the first subassembly; forming a first insulating structure of the first subassembly comprising flowing a first dielectric material into spaces between individual first connectors between the temporary layer and the support element and at least partially curing the first dielectric material; removing the temporary layer so that extremities of the first connectors project beyond a surface of the first insulating structure of the first subassembly; uniting the first connectors with electrically conductive second connectors of a second subassembly juxtaposed therewith to form an assembly, wherein at least one of the first and second subassemblies has at least one microelectronic element mounted to an inwardly facing surface of the respective support element; and forming a second insulating structure comprising flowing a second dielectric material into spaces between adjacent ones of the second connectors and between the first connectors joined thereto.
