Abstract:
A microelectronic assembly comprising:(a) a packaged semiconductor chip including: (i) a semiconductor chip having a front surface with contacts thereon and a rear surface; (ii) a connection component disposed adjacent the chip, said connection component having terminals thereon, at least some of said terminals being connected to at least some of said contacts on the chip, wherein said connection component overlies a surface of the chip, said connection component including a conductive sheet core and a polymeric dielectric coating overlying and adhering to said conductive core, at least some of said terminals being disposed on said coating so that said coating maintains such terminals separate from said core; and (b) a circuit panel larger than said connection component, said packaged chip being mounted on and said circuit panel with said circuit panel extending beyond said connection component, said circuit panel having contact pads thereon, said contact pads of said circuit panel being connected to said terminals of said connection component, said connection component and said substrate having substantially equal coefficients of thermal expansion.
