The in KLayout is a semi-3D visualization tool that extrudes 2D layout polygons into vertical layers with defined thicknesses. To use it, you must run a script—often a variant of a DRC script —to define the material stack and z-levels. The Architect of Silicon
In the world of semiconductor design, visualization is just as critical as routing. For decades, chip designers have relied on flat, top-down 2D views to inspect masks and layers. However, as process nodes shrink (28nm, 16nm, 5nm) and vertical stacking (3D-ICs, FinFETs) becomes standard, the traditional planar view often falls short. klayout 25d view
To activate the 2.5D view effectively, the following workflow is standard: Default control: Click and drag in the 3D window
