Abstract:
1. A microelectronic assembly, comprising: first and second support elements each having first and second oppositely facing surfaces; a microelectronic element mounted to the second surface of a support element of the first and second support elements; electrically conductive first connectors projecting above the second surface of the first support element; electrically conductive second connectors projecting above the second surface of the second support element and coupled to ends of the first connectors; dielectric reinforcing collars surrounding portions of at least some of one or more of: the first connectors, or the second connectors, the dielectric collars configured to substantially prevent collapse of the connectors reinforced thereby when the connectors reinforced thereby are joined with other connectors in forming the assembly, such that the assembly has increased height, and connections between the first and second support elements have increased aspect ratio; and a first encapsulation overlying surfaces of the reinforcing collars, the first encapsulation being formed in contact with at least one of: the second surface of at least one of the first or second support elements; or a second encapsulation formed in contact with the second surface of the another support element, the microelectronic assembly having terminals at the first surface of the second support element, the terminals being electrically coupled with conductive elements on the first support element through pairs of a first connector coupled with a respective second connector.
