Claim:
1. A microelectronic assembly comprising: a plurality of interposers overlying one another and comprising a set of at least two interposers each of which comprises one or more first contact pads; a plurality of first modules each of which is attached to at least one of the interposers and comprises a respective semiconductor integrated circuit and one or more contact pads each of which is electrically coupled to the integrated circuit and connected to a respective first contact pad, wherein each interposer in the set has a first contact pad connected to a contact pad of a first module; wherein at least one of the interposers comprises one or more first cavities, and at least part of each first module is located in at least one respective first cavity; wherein the microelectronic assembly further comprises: one or more first conductive vias each of which passes through at least part of at least respective one of the interposers and reaches at least one respective first cavity and physically contacts, or is capacitively coupled to, circuitry of at least one respective first module at least partially located in the respective first cavity; one or more second conductive vias each of which has a segment which at least partially passes through at least respective two of the interposers outside of any first cavity which have respective first conductive vias.
