Hi All, Has anyone tried and succeeded in processing a 100 micron thin -- die of size 20mm x 20 mm or 2-inch wafers ? What were the main issues you encountered while processing? Is it possible to perform lithography (using contact aligner) on such a thin die or wafer using the alignment features located on the other side (back-side) ? Please share your experiences, either in the forum or in person (by e-mail). Any tip(s)/suggestion(s) are appreciated. Thanks, Vijay TU Delft
