Klayout 25d View Exclusive -

The magic of the 2.5D view lies entirely in . KLayout does not know that Metal 1 is 0.1µm thick and Metal 2 is 0.2µm thick by default. You have to tell it.

KLayout, the open-source GDSII and OASIS file viewer and editor, solves this problem with its feature. Often called a "quasi-3D" viewer, this tool bridges the gap between flat 2D masks and complex, resource-heavy 3D engines. It generates a dynamic, layered preview of your semiconductor stack directly from your mask geometry. What is the KLayout 25D View?

The 2.5D view is accessed through the main toolbar in KLayout. klayout 25d view

For extremely large layouts (>10 GB GDSII), create a quick 25D view by first using Hierarchy > Flatten on selected cells, then reduce detail with Edit > Selection > Convert to polygons with a tolerance of 0.01 µm.

The height where the layer begins relative to the substrate ( Thickness (height): The physical thickness of the material. Step 3: Automate with a Macro (.lym) The magic of the 2

KLayout’s 25D feature requires a few setup steps. It is not enabled by default in minimal installations due to hardware acceleration dependencies.

So next time you’re hunting for a mysterious short or explaining your floorplan to a colleague, tilt your view, extrude those layers, and see your design rise off the plane. KLayout, the open-source GDSII and OASIS file viewer

Unlike a full 3D process simulator that models physical topology (like planarization or conformal etching), the 2.5D view is an extruded 2D view

Once your stackup is configured, you can manipulate the view to inspect intricate details of your design:
