Web1 jul. 2016 · The metal-oxide resists we use offer a high etch capability for EUVL because of their intrinsic properties, 6 and they can therefore serve as a useful alternative to conventional organic films. Compared with CARs (with optimized film thicknesses), the metal-oxide resists offer the advantage of very thin film thicknesses (as low as 20nm), … http://www.chipmanufacturing.org/h-nd-240.html
WebThe first double patterning technique, litho-etch litho-etch (LELE), is the most straightforward. It consists of an initial lithography step followed by an etching step and then the same process is repeated to get the final pattern, see figure 1. The negative aspects of this technique are that two masks must be used to create the final pattern.
