Litho etch thin film diffusion cmp等制程机理研究

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.
