Web2.1 Image MEEF Fundamentally, what is the cause of MEEF values other than one? Anything that causes the overall imaging process to be non-linear will lead to a non-unit valued MEEF. In lithography, every aspect of the imaging process is non-linear to some degree, with the degree of non-linearity increasing 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).
