Zusammenfassung:Various substrates or circuit boards for receiving a semiconductor chip and methods of processing the same are disclosed. In one aspect, a method of manufacturing is provided that includes forming a first opening in a solder mask positioned on a side of a substrate. The first opening does not extend to the side. A second opening is formed in the solder mask that extends to the side. The first opening may serve as an underfill anchor site.
