Abstract
The present disclosure, in some embodiments, relates to a semiconductor structure. The semiconductor structure includes a substrate and a first conductive pad arranged over the substrate. A boundary structure is on an upper surface of the substrate around the first conductive pad. The boundary structure has one or more sidewalls defining an opening with a round shape over the first conductive pad.
