摘要: The embodiments of bump and bump-on-trace (BOT) structures provide bumps with recess regions for reflowed solder to fill. The recess regions are placed in areas of the bumps where reflow solder is most likely to protrude. The recess regions reduce the risk of bump to trace shorting. As a result, yield can be improved.
