SAHR(TM) [1-3] (Silylated Acid Hardened Resist) employs chemically amp
lified crosslinking of exposed areas and results in positive-toned fea
tures following dry development. Two undesirable characteristics of th
is process have been identified and explained in terms of physical che
mical properties of the materials used. Two very simple process modifi
cations are presented as solutions to these problems. Data is presente
d which shows how these modifications work to improve lithographic per
formance.
