In addi- tion, it can provide increased visual contrast at the pat- terned resist inspection stage (6). A variation on the visual contrast improvement involves the … WebJul 7, 1997 · This paper explores through numerical simulation and experiment the role of partial coherent illumination on reflective notching in optical projection printing over a nonplanar substrate. The intensity in the photoresist when patterning a gate line over a LOCOS generated active area well covered in polysilicon was simulated with the rigorous …
Dyed resist for the reduction of reflective notching (Conference ...
WebReflective notching results when the exposing light strikes a surface which is not perpendicular to the incoming ray and is scattered into a region which was intended to … 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. getfullyear is not a function angular
