Web1 jun. 2008 · In Inverse Lithography Technology (ILT), MEEF can be included in the cost function as a nonlinear factor, so that the inversion minimizes MEEF, in addition to … Web1 jul. 2014 · The MEEF is determined by a programmed mask with features varied in a reasonable range to represent the mask process variation and the relevant wafer CDs after performing the lithography process. As shown in Fig. 5, the measured MEEF, however, is a global MEEF (G.MEEF) instead of a local MEEF (L.MEEF).
