Abstract:
A method of fabricating a pillar-type connection includes forming a first conductive layer. A second conductive layer is formed on the first conductive layer to define a conductive pillar that includes a top surface defining a recess aligned with a hollow core of the first conductive layer. A conductive via that terminates at a top surface of the first conductive layer is formed.
