EUTECTIC SOLDER STRUCTURE FOR CHIP |
摘要 |
The present invention provides a eutectic solder structure for a chip including a substrate and a solder structure on the substrate. The solder structure includes an alternate lamination of a plurality of first metal layers and a plurality of second metal layers, wherein each second metal layer has a continuous region and a plurality of openings and the melting point of the plurality of second metal layers is higher than that of the plurality of first metal layers. The eutectic solder structure for a chip also includes a chip on the solder structure, wherein the chip is bonded to the substrate by a eutectic reaction of the solder structure. |
