  • Patent number: 9472420
    Abstract: Aqueous compositions for stripping titanium nitride (TiN or TiNxOy) hard mask and removing etch residue are low pH aqueous composition comprising solvent, a weakly coordinating anion, amine, and at least two non-oxidizing trace metal ions. The aqueous compositions contain no non-ambient oxidizer, and are exposed to air. Bifluoride, or metal corrosion inhibitor may be added to the aqueous composition. Systems and processes use the aqueous compositions for stripping titanium nitride (TiN or TiNxOy) hard mask and removing titanium nitride (TiN or TiNxOy) etch residue.
    Type: Grant

  • Patent number: 7452426
    Abstract: Process solutions comprising one or more surfactants are used to reduce the number of defects in the manufacture of semiconductor devices. In certain preferred embodiments, the process solution of the present invention may reduce defects when employed as a rinse solution either during or after the development of the CMP processing. Also disclosed is a method for reducing the number of defects on a plurality of post-CMP processed substrates employing the process solution of the present invention.

  • Patent number: 7348300
    Abstract: Disclosed herein are process solutions, which may be aqueous-based, non-aqueous-based, and combinations thereof, that contain at least one alkoxylated acetylenic diol surfactant. In one aspect, the process solution comprises water and an alkoxylated acetylenic diol surfactant having the formula A: where r and t are 1 or 2, (n+m) is 1 to 30 and (p+q) is 1 to 30.
