Mastering the KLayout 25D View: A Deep Dive into 2.5D Visualization for IC and MEMS Design

: Changing the fill color or pattern in the layer list will update the "face" color of the extruded blocks in real-time. Pivot Point

1. Open the Layer Properties (right-click the layer list or View > Layer Properties).
2. Select a layer (e.g., "Metal1").
3. Look for the "3D" tab within the Layer Properties dialog.
4. Check "Use 3D extrusion".
5. Set the "Height" value (in Microns or database units).

   7. Conclusion

   Beyond the Flat Plane

   Unlike a true 3D viewer that might support arbitrary angles and curved surfaces, the 2.5D view in KLayout works strictly by taking 2D polygon layers and extruding them vertically. It cannot model complex process topologies (like conformal coverage) but excels at showing how different metal, poly, and diffusion layers sit on top of each other.

   6. Limitations

   2.5D Scripting

   : To use the tool, you must create a script that defines how the layers are stacked and extruded. These scripts use a variant of the DRC (Design Rule Check) language . Open the Layer Properties (right-click the layer list
