摘要: The mechanisms for forming metal bumps to connect to a cooling device (or a heat sink) described herein enable substrates with devices to dissipate heat generated more efficiently. In addition, the metal bumps allow customization of bump designs to meet the needs of different chips. Further, the usage of metal bumps between the semiconductor chip and cooling device enables advanced cooling by passing a cooling fluid between the bumps.
