View: Klayout 25d

When training new layout engineers, it is difficult to explain that a "Contact" is a hole in the oxide, not a physical block. In 2.5D, you can set the "Implant" layer to height 1, "Oxide" to height 10 (transparent), and "Contact" to height 11. The student literally sees the contact piercing the oxide.

  • Set the "Sidewall color" – usually a darker shade of the fill color.

    • While powerful, the KLayout 2.5D view has distinct limitations compared to commercial TCAD tools: klayout 25d view

    KLayout's 2.5D (often called "25D") view provides a simple and effective way to visualize layered semiconductor layouts with an embossed, height-coded representation that helps designers inspect layer stacking, overlaps, and process-related thickness information. When training new layout engineers, it is difficult

    Open your GDSII or OASIS file (File > Open). Ensure you have a technology file loaded (.lyp or .lyt) so layers have proper colors and names, though this isn't strictly required. Set the "Sidewall color" – usually a darker
