Beyond Flatland: Mastering the “2.5D View” in KLayout for Enhanced IC Layout Analysis

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.

• Z-Position: The vertical starting height of the layer.
• Thickness: The physical thickness of the material.
• Material Properties: Users can assign colors and transparency to simulate visual properties of specific materials (e.g., Silicon, SiO2, Metal).

Create a New Script: Go to Tools > 2.5d View > New 2.5d Script. This opens a new script template in the macro editor. klayout 25d view

Step 3: Launch the 25D Window

Navigate to View > New 2.5D View. A separate window opens, initially showing your layout as a flat, extruded landscape. Use the mouse: Beyond Flatland: Mastering the “2
