Abstract
Dendritic compounds are provided. The dendritic compounds include an anionic dendron that has a focal point having an anionic group and a linking group, and a photoreactive cation. The dendritic compounds find particular use as photoacid generators. Also provided are photoresist compositions that include such a dendritic compound, as well as methods of forming electronic devices with the photoresist compositions. The dendritic compounds, photoresist compositions and methods find particular applicability in the manufacture of semiconductor devices.
