Abstract:
Methods of dicing semiconductor wafers are described. In an example, a method of dicing a semiconductor wafer having integrated circuits thereon involves forming a mask above the semiconductor wafer, the mask composed of a layer covering and protecting the integrated circuits. The mask is then patterned with a multiple pass laser scribing process to provide a patterned mask with gaps exposing regions of the semiconductor wafer between the integrated circuits, the multiple pass laser scribing process including a first pass along a first edge scribing path, a second pass along a center scribing path, a third pass along a second edge scribing path, a fourth pass along the second edge scribing path, a fifth pass along the center scribing path, and a sixth pass along the first edge scribing path. The semiconductor wafer is then plasma etched through the gaps in the patterned mask to singulate the integrated circuits.

Claim (Index 12):
The method of  claim 11 , wherein patterning the mask with the multiple pass laser scribing process comprises forming trenches in the regions of the semiconductor wafer between the integrated circuits, wherein plasma etching the semiconductor wafer comprises extending the trenches to form corresponding trench extensions, and wherein the trenches have a width of approximately 20 microns and a depth in the range of 5-6 microns.
