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.

Webimmersion litho defects at a lower cost-of-ownership. This paper describes litho monitoring methodologies developed and implemented for flash devices for 65nm production and 45nm development using the darkfield imaging inspector. Keywords: after-develop inspection, photo-cell monitoring, litho monitoring, darkfield inspection 1. INTRODUCTION WebOffset lithography printing, given the multitude of material choices, produces more frequent print defects relating to non-conforming materials. The International Standards Organization has developed several standards to define the quality of graphic images, based on various perspectives such as tone, colour, resolution, contrast, etc. billy strings bronzeback
