You start with a pattern layout. Run the etch process. The result? You get uneven depths — some areas too shallow, others too deep. That’s where design-level solutions come in. With dummy patterning and virtual process modeling, engineers simulate how etchants behave across different layout geometries before ever touching a wafer.
