Abstract: The present disclosure generally relates to ensuring a plasma plume or cloud that forms during a laser cutting process does not lead to undesired re-deposition of material onto the substrate. At least one electrode is biased to draw the electrons of the plasma plume or cloud towards the electrode and away from the substrate. A vacuum port and/or a blower may be strategically located to ensure proper gas flow away from the substrate and hence, directing of the electrons away from the substrate. In so doing, material re-deposition is less likely to occur.

Abstract: A semiconductor device includes a die stack having dies selected into the stack based on their thicknesses. After the dies are formed on a wafer and thinned, a metrology tool is used to determine the thicknesses of the dies in the wafer.

In one example, dies which have been classified into bin 1 (having an optimal thickness) are selected to provide a high capacity highly reliable semiconductor device. In a further example, dies of different bins are mixed and matched to provide a uniform, highly controlled overall die stack height.
