Abstract

An electronic structure includes a first substrate having a first under bump metallization (UBM) region and a second UBM region formed thereon. One or more solder bumps is deposited onto the first UBM region. A downstop formed on the second UBM region is wider, shallower and more rigid than any one of the solder bumps formed on the first UBM region. A second substrate is joined to the first substrate by the one or more solder bumps located on the first UBM region, and a height of the downstop limits a distance between at least one of the first substrate and the second substrate, or between an object and at least one of the first substrate and the second substrate.
