Claim:
1. A method used during fabrication of a semiconductor device, comprising: prior to the formation of a first feature, determining a profile issue associated with formation of the first feature to be formed using a first photosensitive material formulation, wherein the profile issue is one of a footing profile issue, a T-top profile issue, an undercut profile issue, and top rounding profile issue; determining a modification of the first photosensitive material formulation to compensate for the profile issue, wherein the modification includes adjusting at least one of an acid loading and a base loading of the first photosensitive material formulation to provide a modified photosensitive material thereby mitigating the profile issue, wherein the determining the modification of the first photosensitive material formulation includes providing a formulation including a solvent, a photoacid generator, and a quencher and wherein the quencher has a formula wherein R4, R5 and R6 are alkyl fluoride and one of R4, R5, and R6 is C forming a layer of the modified photosensitive material on a substrate; and after the forming the layer, patterning the layer of the modified photosensitive material using an exposure to a radiation beam and development of the exposed layer of the modified photosensitive material to provide the first feature of the modified photosensitive material, wherein the patterning provides the first feature with straight sidewalls.
