Zoom into the specific cell or region of interest (rendering an entire multi-billion transistor chip in 25D is not recommended).

To make the 2.5D view actionable, hide unused or non-functional layers so you can focus on the interconnects and devices.

Renders significantly faster than full 3D CAD engines, allowing you to parse massive GDSII files smoothly. Step-by-Step Guide to Setting Up KLayout 25D View

The GDS/OASIS layer map (e.g., 6/0 for Polysilicon). Elevation (Z-Start): The distance from the substrate base ( ) to the bottom of the layer.

You can often adjust the "Z-scaling" factor. Since many chip layers are very thin (nanometers) compared to their width (microns), increasing the Z-scale helps you see the vertical details more clearly. Why use 2.5D instead of 3D? klayout 25d view

In MEMS design, use the 25D view to check if etched release channels will accidentally breach neighboring structural walls.

Unlike commercial verification tools that can be costly and slow, the 2.5D viewer in KLayout is free, fast, and seamlessly integrated into the editor. How to Access and Use the 2.5D View in KLayout

It is much easier to see if a via is "floating" or if a metal layer is missing its underlying insulation in a 2.5D space than by looking at overlapping flat colors.

The actual vertical thickness of the material.

Click and drag your left mouse button to rotate the chip along the X, Y, and Z axes.

The layer definition is controlled via a simple configuration script or graphical table within the plugin interface. You must specify three critical parameters for each layer:

Unlike a true 3D CAD model that uses complex solid geometries (like voxels or boundary representations), a 25D engine simply extrudes 2D polygons along the Z-axis. It gives the illusion of 3D depth, which is perfectly suited for semiconductor manufacturing stacks where layers are deposited sequentially on top of one another. Why Use 25D View in KLayout?
