Abstract:
A semi-aqueous wet clean system and method for removing carbon-containing silicon material (e.g., plasma residue) or nitrogen-containing silicon material (e.g., plasma residue) includes a hydroxyl-terminated organic compound, a diol, and a fluoride ion donor material. The system is configured to protect silicon oxide and amorphous silicon during a post-dry-etch wet clean. The wet clean system is configured to selectively remove carbon-containing or nitrogen-containing plasma residue. pH of the wet clean system can be modified to tune selectivity for removal of carbon-containing or nitrogen-containing plasma residues. As a result, positive TEOS recession of less than about 3 nanometers may be achieved. Additionally, the wet clean system can be adapted for reclamation and subsequent reuse.

Claim (Index 16):
The method of  claim 15 , wherein the cleaning comprises at least partial removal of the at least one of the carbon-containing silicon residue or the nitrogen-containing silicon residue from a silicon-containing structure.
