Webthe litho–cure–litho–etch (LCLE) process has been introduced as an alternative technique. In this study, the LCLE process is modelled and simulated to explore the pattern formation between the two lithography processes (litho 1 and litho 2). This process allows for the physical phenomena of pattern formation to be better understood.

WebLithografie is een zogenaamde vlakdruktechniek. Het woord is afgeleid van de Griekse woorden λίθος (lithos – steen) en γράφειν (grafein – tekenen/schrijven). Bij lithografie wordt de steen niet ingekerfd, bekrast of gesneden zoals in bijvoorbeeld een houtsnede, maar deze techniek maakt gebruik van de chemische eigenschappen van olie en water.
