Hybrid laser and plasma etch wafer dicing using substrate carrier
Abstract:
Methods of and apparatuses for dicing semiconductor wafers, each wafer having a plurality of integrated circuits, are described. A method includes forming a mask above the semiconductor wafer, the mask composed of a layer covering and protecting the integrated circuits. The semiconductor wafer is supported by a substrate carrier. The mask is then patterned with a laser scribing process to provide a patterned mask with gaps, exposing regions of the semiconductor wafer between the integrated circuits. The semiconductor wafer is then etched through the gaps in the patterned mask to singulate the integrated circuits while supported by the substrate carrier.
