IC HAVING ELECTRICALLY ISOLATED WARPAGE PREVENTION STRUCTURES
摘要:
Disclosed aspects include a semiconductor die including a substrate having a semiconductor surface including circuitry. A top metal layer is above the semiconductor surface including top metal lines that are electrically connected through a metal stack including metal interconnects that electrically connect to the circuitry. The top metal lines are configured in a primary orientation that collectively represents at least 50% of a total length of the top metal lines in a first direction. The top metal layer includes bond pads exposed from a passivation layer. The metal features are positioned lateral to and not directly electrically connected to the top metal layer and/or are positioned on the passivation layer. At least a majority of a total area of the metal features is not over metal interconnects. The metal features have a length direction oriented in a second direction that is at least essentially perpendicular relative to the primary orientation.
