Abstract:
1. A method for removing an ion implanted photoresist material from a semiconductor structure comprising: providing a patterned photoresist on a surface of a semiconductor structure, said patterned photoresist having at least one opening therein that exposes an upper surface of a semiconductor substrate of the semiconductor structure; introducing dopants into the exposed upper surface of the semiconductor substrate as well as the patterned photoresist by ion implantation; forming a polymeric film containing at least one lanthanide metal-containing oxidant on at least exposed upper surfaces of the ion implanted and patterned photoresist; performing a baking step causing a reaction between the polymeric film and the ion implanted and patterned photoresist in which a modified patterned photoresist that is soluble in aqueous, acid or organic solvents is formed; and removing the modified patterned photoresist from the semiconductor structure using an aqueous, acid or organic solvent.
