Lead configurations

A microelectronic lead element comprising:

• a first strip-like leg having a surface releasably attached to a first substrate, said first strip-like leg having a base end and a first tip end permanently connected to said first substrate, and
• a second strip-like leg having a surface releasably attached to a second substrate, said second strip-like leg having a base end and a second tip end permanently connected to said second substrate, the base ends of said legs being electrically connected together, wherein movement of said first tip end relative to said second tip end in a vertical direction will cause flexure of said legs in opposite directions upon release of said legs from said first and second substrates.

A combination of a microelectronic lead element connecting first and second microelectronic elements, said lead element comprising:

• a strip-like first lead having a surface releasably attached to a first microelectronic element, said first lead having a tip end permanently connected to said first microelectronic element and a base end releasably attached to said first microelectronic element,
• a strip-like second lead having a surface releasably attached to a second microelectronic element, said second lead having a tip end permanently connected to said second microelectronic element and a base end releasably attached to said second microelectronic element, said first microelectronic element facing said second microelectronic element in spaced apart relationship with said first and second leads disposed therebetween with said leads arranged in vertical alignment with respect to each other,
• bonding material electrically connecting said base ends of said first and second leads together, wherein movement of said tip ends relative to each other in a vertical direction will cause flexure of said leads in opposite directions upon release of said leads from said first and second microelectronic elements while said tip ends remain permanently connected to said first and second microelectronic elements.
