WebLet’s say we wanted to model the whole process from litho to fabrication. This is exactly what Coventor, Panoramic Technology and ASMLdid in material they showed at SPIEa few weeks ago. They used HyperLith from Panoramic Technology to predict the resist contours at a variety of doses and defocus values (0 to +/-50nm). WebLithografie is een grafische techniek die tot de vlakdruk behoort. Het woord is afgeleid van de Oudgriekse woorden λίθος lithos (steen) en γράφειν graphein (tekenen/schrijven) en betekent steendruk..
