  • Patent number: 10613442
    Abstract: The present invention is a charge complexing chemical composition that protects metal during polymer removal. The polymer coatings include crosslinked systems by chemical-amplification and photoacid generated (PAG) means as in epoxies. The system includes a solvent, a charge complexing additive, and an acid that creates a protective complex for sensitive metals during the dissolving and rinsing practice needed for processing microelectronic parts. The composition can be utilized with a method for removing partial and fully cured crosslinked coatings that originate from chemical amplification or PAG-epoxy photoimageable coatings.
