Analysis of Focus Errors in Lithography using Phase-Shift Monitors

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.. Lithografie maakt gebruik van het vet in het tekenmateriaal en in de drukinkt.Als drager van de tekening dient een bepaald soort kalksteen of (tegenwoordig) … WebEen Litho is een afbeelding gemaakt volgens het principe dat water en vet elkaar afstoten. Het drukproces is een behoorlijk specialistisch karwei. Omdat de term Litho en de techniek niet bij iedereen bekend is, geven wij hier een beknopte uitleg: De techniek: graham nolan\u0027s: the chenoo

Web1.1 Introduction to Optical Lithography As critical dimensions(CD’s, also called “feature size”) in the rapid development of the semiconductor industry have been continuously reduced, the improvement of optical lithography has played a very important role in the semiconductor industry. Lithographic requirements differ from chip to chip. WebKeywords: Lithography, Focus, Phase-Shift Focus Monitor, 1. INTRODUCTION As the dimensions of devices shrink, the numerical aperture of the lithography scanners increases and the actinic wavelength decreases. This leads to a reduction of the useable depth of focus for lithography printing, as is illustrated in Figure 1.
