We report on replication of high resolution patterns over a 4 in, wafer are
a by imprint lithography with a commercial hydraulic press and a pair of ho
t plates. The experiments confirm that the imprint lithography can be used
for large area patterning. As a result, sub-100 nm features were obtained b
y the imprint lithography and lift-off with a good uniformity and an accura
te pattern placement over the 4 in. wafer area.
