He used a comparison with commercial aviation to highlight his point. Making faster airplanes isn\u2019t all that difficult; making money from them is \u2013 where\u2019s Concorde now<\/a>? Just as commercial aviation has reached a speed plateau and seeks to expand by changing other variables such as capacity (see the humongous Airbus A380<\/a>), so the drive to use smaller and smaller wavelengths for photolithography<\/a> is no longer the focus of the semiconductor industry. Techniques to improve the resolution of established 193 nm lithography – such as immersion lithography<\/a> \u2013 may be the way forward.<\/p>\n

Willson then went on to discuss imprint lithography techniques, such as his step-and-flash nanoimprint lithography<\/a>, which set the scene for the rest of the session. Although it is quite clear that optical lithography is the current standard, nanoimprint lithography<\/a> seems set to make a big impression.<\/p>\n
