25d View | Klayout

The Z-start or thickness values for your layers are likely set to zero, or the layers are not bound to active GDS layer numbers.

MEMS devices rely heavily on vertical suspension, air gaps, and cavity etching. Silicon photonics layout requires precise waveguide positioning relative to cladding layers. Visualizing these devices in 2.5D ensures the structural integrity of the physical device matches design intent. 3. Debugging Complex DRC Errors

# Example to extrude Metal 1 from z=0.1 to z=0.3 z(input(10, 0), zstart: 0.1, zstop: 0.3, name: "Metal1") Use code with caution. Limitations and Practical Constraints

2D shapes given a fixed thickness (height) and a z-offset (elevation). Key Features The Z-start or thickness values for your layers

This opens the macro editor, where you can define your process stack. 3. Basic Script Syntax (2.5D Script Anatomy)

In advanced CMOS processes, a single signal path may traverse a dozen metal layers. Misaligning a single via creates an open circuit. By isolating the net and viewing it in 25D, you can trace the vertical staircase from Metal 1 all the way to the top global routing layer. 3.
