Optimized power delivery to high speed, high pin-count devices

摘要

A high-speed semiconductor device includes a substrate having an upper substrate surface, a lower substrate surface, and a periphery bounding the upper and the lower substrate surfaces, the substrate further having an upper substrate ground trace providing an electrical path to the lower substrate surface through a substrate ground via; an array of solder balls attached to the lower substrate surface, the array of solder balls including a plurality of ground solder balls disposed at the periphery and electrically connected to the substrate ground via.
