A connection component for use in making microelectronic element
assemblies which has peelable leads that are formed on a dielectric
support structure. One end of each lead is permanently connected to the
support structure and the opposite end of the lead is releasably
connected to the support structure. When the releasable end of the lead
is bonded to a contact on a semiconductor chip, the releasable end of the
lead can be peeled from the support structure such that the chip may be
moved away from the support structure. A compliant layer may be disposed
between the chip and the support structure. If a compliant material is
injected between the chip and the support structure to form the compliant
layer, the compliant material will lift the chip away from the support
structure and facilitate the peeling of the leads from the support
structure.
