Lithography defects
WebAs with exposure dose, the optimal focus offset for a given process must usually be determined experimentally. On stepping exposure systems where many exposures occur … WebParticulates result in defects in the final resist pattern, whereas film contamination can cause poor adhesion and subsequent loss of linewidth control. Particulates generally …
