Abstract
A semiconductor device has a semiconductor die. The semiconductor die has a contact pad. A first conductive layer is formed over the contact pad. A conductive shell having a hollow core is formed over the first conductive layer. A compliant material is deposited in the hollow core. The semiconductor die is mounted over a substrate with the conductive shell electrically connected to a conductive trace on the substrate. A second conductive layer is formed over the conductive shell. The compliant material is an insulating material. A bump material is deposited around the conductive shell. A pre-solder material is deposited over the conductive trace. The conductive shell has a cross-sectional width less than 7 micrometers. The second conductive layer is a conductive lip. Mounting the semiconductor die over the substrate further includes mounting the semiconductor die over the substrate in a bump on lead (BOL) configuration.
