DuPont’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 are part of our EKC Technology portfolio.
Those products are designed to clean residues created during the etch process, while keeping compatibility with exposed metal and dielectric materials. DuPont has products for Aluminum process integration, and more recently for Copper process integration.
Aqueous & semi-aqueous organic mixtures formulated to effectively remove residues from substrate surfaces after via, poly and metal etch processes.
DuPont’s post-etch residue removers are aqueous and semi-aqueous organic mixtures formulated to effectively remove residues from substrate surfaces.
DuPont’s post-etch residue removers for copper (Cu) applications include CuSolve™ copper integration technology and SAC™ semi-aqueous chemistry removers.
Aqueous formulations employed for post-CMP cleaning are designed to protect the planarized metals and dielectrics preventing metal corrosion while providing a smooth defect free wafer surface.
