Research output: Chapter in Book/Report/Conference proceedingConference contribution


A two-stage replication molding method for fabricating ordered submicron sized features over a large area of biomedical poly(urethane urea) (PUU) was investigated. A lithographic technique was used to fabricate a master pattern in a photosensitive resist on a 150 mm diameter silicon wafer. The replication efficiency for each pillar width was calculated as the percentage of the 5×5 pillar array present. The monolayer was shown to reduce replication efficiency and accurate replication was obtained to the resolution limit of 309 nm without it.
