Photoresist compositions with pendant polar-functionalized aromatic groups and acid-labile branching

Acid-catalyzed positive photoresist compositions having generally improved performance (especially photoresist compositions having improved contrast (solubility differential), shrinkage and processing kinetics on radiation exposure) are obtained by use of polymers containing pendant polar-functional...
