摘要:
A novel cleaning composition used for post-etch resist residue removal is disclosed. In contrast to the conventional cleaning solutions based on fluoride chemistries, the present invention can significantly reduce the oxide loss resulting from the exfoliation, while still providing an excellent cleaning efficiency.
