Qnity’s post-etch residue removers are aqueous and semi-aqueous organic mixtures formulated to effectively remove residues from substrate surfaces after via, poly and metal etch processes. Post-etch residue removers (PERR) are part of the core product offering from our EKC Technology portfolio.
EKC4000 PCT is a cost-effective replacement that outperforms conventional "rinse" chemistries such as IPA and NMP. It quickly and effectively eliminates corrosion on the wafer surface caused by drag-out (carry over) of chemistry from prior wet cleaning. EKC4000 PCT is compatible with automatic equipment and is formulated to meet ULSI grade specifications for advanced wafer treatment.
