WebOne effect of the reflectivity of such substrates is linewidth variation known as reflective notching which severely impacts process latitude and device reliability. In recent years, strongly absorbing intermediate layers or ARCs, both organic and inorganic, have seen widespread implementation to control reflective notching. WebVariation in line width caused by light scattered from the substrate (reflective notching) is a major problem in VLSI lithography. This paper demonstrates the reduction of reflective notches using a resist with increased absorptivity (a dyed resist). The optimal set of process conditions which minimize line width variations is explored.
