Mechanically compliant bumps for flip-chip bonding have a base that is deposited, for example, on the contact pad of a semiconductor chip. A thin wall depends from the periphery of the upper surface of base. The wall advantageously completely encircles the upper surface of the mechanically compliant bump. The wall, which is capable of flexing or deforming under pressure provides mechanical compliance. The wall is able to flex or deform under pressure even if the bump is formed from high-temperature metal. These mechanically compliant bumps facilitate sound electrical connections even when an electronics device is brought into contact for bonding out of parallel. |
