Post-CMP Cleaners

Chemical mechanical planarization (CMP) is a critical enabling technology in advanced integrated circuit manufacturing. Defects and residues either deposited or formed during the planarization process that can adversely affect product yield are subsequently removed in the post-CMP cleaning step. Aqueous formulations employed for post-CMP (PCMP) cleaning are designed to protect the planarized metals and dielectrics preventing metal corrosion while providing a smooth defect free wafer surface.

DuPont’s PCMP offerings are part of our EKC Technology portfolio.
