Investigation of Defectivity Coming from the Back Side of Wafers during AlCu Polymer Removal Processes Performed in a Batch Spray Tool

The defectivity of a batch process for polymer removal in AlCu BEOL technology has been investigated, reasearching the defectivity source and studying the composition of the defects. Different solutions for the minimization of this defectivity have been found, working on the positioning of the wafer...
