Abstract: An integrated circuit assembly 10 is provided, including a substrate 14 having at least one substrate contact surface 18, an integrated circuit device 12 having at least one first contact surface 16, and a bar bond element 22. The bar bond element 22 provides communication between the at least one substrate contact surface 18 and the at least one first contact surface 16. The bar bond element 22 includes a conductive plate element 23 having an integrated circuit foot portion 24, a substrate foot portion 26 and a strain relief loop 46 positioned between the integrated circuit foot portion 24 and the substrate foot portion 26.

Abstract: A method and assembly for mounting an IC semiconductor device to a substrate using flip chip technology. The assembly generally entails a flip chip having a first surface, an oppositely-disposed second surface, an integrated circuit that includes a vertical device on the first surface, and an electrical contact for the vertical device on the second surface. The flip chip is bonded with first solder connections to a first conductor pattern on a substrate, so that the first solder connections electrically and mechanically connect the flip chip to the substrate. The assembly further includes an electrical contact member that is positioned so that the flip chip is between the contact member and the substrate. The contact member is electrically and mechanically connected to a second conductor pattern on the substrate with second solder connections. A third solder connection electrically and mechanically connects the contact member to the electrical contact on the second surface of the flip chip.
