Abstract:
A method and composition for removing bulk and/or ion-implanted resist material from microelectronic devices have been developed. The compositions effectively remove the ion-implanted resist material while not damaging the silicon-containing or germanium-containing materials.

Claim (Index 34):
A composition comprising (a) at least one non-oxidizing acid present in an amount greater than 80 wt %, at least one of a fluoride species and/or a bromide compound, and at least one compound that lowers the melting point of the composition, with the proviso that the composition is substantially devoid of oxidizers, and wherein the pH of the composition is less than 2 or (b) a sulfur-containing acid present in an amount greater than 90 wt %, HCl, and optionally at least one fluoride and/or at least one bromide compound, wherein when in contact with a surface of a microelectronic device, the composition removes ion-implanted resist material from the surface of the microelectronic device while not substantially damaging silicon-containing materials and germanium-containing materials present on the surface of the microelectronic device.
