Packaged Semiconductor Chip Comprising An Integrated Circuit Chip Ablated With Laser And Cut With Saw Blade From Wafer
摘要:
A packaged semiconductor chip comprising an integrated circuit chip including a low-k dielectric layer and a chip substrate, wherein an edge of the integrated circuit chip has a first edge portion and a second edge portion. At least part of the first edge portion being across a same level as the low-k dielectric layer, and the first edge portion having been laser ablated to have a series of rounded recesses formed therein. The second edge portion being across a same level as at least part of the chip substrate, and the second edge portion having a different surface texture than that of the first edge portion. The packaged semiconductor chip also comprises a packaging substrate having the integrated circuit chip attached and a plurality of solder bumps electrically connecting between the packaging substrate and the integrated circuit chip.
