Abstract:
A removal composition and process for selectively removing p-doped polysilicon (e.g., boron-doped polysilicon) relative to silicon nitride from a microelectronic device having said material thereon. The substrate preferably comprises a high-k/metal gate integration scheme.

Claim (Index 1):
A method of selectively removing p-doped polysilicon relative to silicon nitride, said method comprising contacting a substrate comprising p-doped polysilicon and silicon nitride with a removal composition, wherein the removal composition selectively removes the p-doped polysilicon relative to silicon nitride and comprises at least one nitrate, at least one fluoride, at least one strong acid, optionally at least one silicon source, optionally at least one reducing agent, and optionally at least one solvent.
