Layer colors from your standard GDS palette are preserved, but transparency can be adjusted. This prevents occlusion when many layers are extruded simultaneously.
KLayout's 2.5D (often called "25D") view provides a simple and effective way to visualize layered semiconductor layouts with an embossed, height-coded representation that helps designers inspect layer stacking, overlaps, and process-related thickness information.
Because it is an extrusion-based approach, it is significantly faster than rendering a true, realistic 3D model. klayout 25d view
Once your stackup is configured, you can manipulate the view to inspect intricate details of your design:
Adjust the “height” factor in layer properties to exaggerate thickness for better visibility. Layer colors from your standard GDS palette are
: The 2.5D view inherits colors directly from your active KLayout Layer Properties . If you hide a layer or change its fill color in the main window, the 2.5D view updates accordingly.
: KLayout must be compiled with OpenGL support for the 2.5D viewer to work. Performance Limits Because it is an extrusion-based approach, it is
Work inside a specific leaf cell rather than the top-level chip array.
: The GDSII/OASIS layer identifier (e.g., 1/0 for Polysilicon).
