Nanometre-scale printing technique could put its stamp on the electronics industry

This year marks 20 years since Stephen Chou, Peter  Krauss and Preston Renstrom first published their work showcasing a versatile approach for mass production of identical nanostructures for the electronics industry. This technique is called nanoimprint lithography and it involves pressing a nano-patterned structure into a hot molten polymer. As the polymer cools, the pattern stamped into it sets so that it can be used as a mould to make several identical replicas of the original structure.

Just as the printing press brought literature to the masses, it is easy to imagine how this nanofabrication technique could have a significant impact on the production of integrated circuits. To commemorate the development, Nanotechnology has published a perspective article on the technique, and I had a chance to talk to the author Qiangfei Xia of the University of Massachusetts at Amherst about the technique’s advantages, challenges and outlook for the future.

Daresbury holds a ‘wedding for microscopists’

Last month on a rainy grey morning in north-east England I headed to the Daresbury Laboratory as the SuperSTEM lab there celebrated the installation of its latest world-class microscope. Industrial and academic microscopists from around the world gathered for the inauguration, which was described as a “wedding for microscopists” because so many people from the tightly knit microscopy community were there. You can hear the excitement in the audio piece below, where SuperSTEM lab director Quentin Ramasse and other researchers at the event tell me their plans for the new instrument.
