Klayout 25d — View Patched

It emphasizes layer stackups and vertical interconnects (vias) without the visual clutter of organic, non-planar topological variations.

Simulates complex physics, conformal depositions, non-planar etching, and true rounded topologies (like a chemical-mechanical planarization process).

Easily identify if a via is missing its landing pad or if a metal trace is accidentally shorting on a different plane. How to Use the 2.5D View klayout 25d view

Step 2: Configuring the Layer Stack (The .lyp or Script Setup)

to move from a visual representation to physical simulation. DRC-style script to help you set up your first 2.5D material stack? The 2.5d View - KLayout Layout Viewer And Editor How to Use the 2

It is not a full 3D simulator – and that is perfectly fine. For tape-out checks, MEMS topology inspection, and even client presentations, the 2.5D perspective offers the best trade-off between speed, clarity, and physical insight. With a few minutes of layer height assignment, you can see your design the way it will exist on silicon: as a three-dimensional object, not just a geometric abstraction.

: Unlike a "true" 3D engine, this tool uses a script to define the material stack, assigning specific thicknesses and starting heights to 2D polygon layers. OpenGL Support For tape-out checks, MEMS topology inspection, and even

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

Once you drag the angle below 80°, you will see the polygons pop up into "walls."

Pro Tip: You can save this stack configuration file so you don't have to re-enter process parameters every time you open a new layout. Step 4: Render and Navigate

To display a 2.5D structure accurately, KLayout needs to know the physical dimensions of your process node. It needs to know how high Metal 1 sits above the silicon, and how thick it is.
