Use of non-oxidizing strong acids for the removal of ion-implanted resist

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.
