zz { ... } : This combines multiple z statements into a single display group for easier material management.

The 2.5D view respects your 2D layout settings. If you change a layer's fill color or hide it in the main viewer, it will update in the 2.5D window.

The 2.5D view is only available if your KLayout build was compiled with OpenGL support . klayout 25d view

A dedicated list on the right allows you to toggle specific material groups on or off, which is useful for "peeling back" upper metal layers to see lower-level transistor structures.

Because semiconductor layers are often very thin relative to their width, the 2.5D view includes a on the right side of the window. Increasing this factor exaggerates the vertical dimensions, making it easier to see height variations that would otherwise appear flat. Advanced Visualization Features If you change a layer's fill color or

z(layer, zstart: 0.0, height: 1.0) : This extrudes a specific layer from a base (zstart) to a certain thickness (height).

Unlocking the KLayout 2.5D View: A Comprehensive Guide KLayout's is a specialized visualization tool that transforms flat 2D mask layouts into semi-3D representations through vertical extrusion. Introduced in version 0.28, this feature allows designers to inspect the vertical stack of a semiconductor process, helping to visualize wiring congestion and relative material heights. What is 2.5D View? Because semiconductor layers are often very thin relative

Currently, the tool has a practical limit of approximately 100,000 polygons . Setting Up Your First 2.5D Scene
