gdsfactory.technology.LayerStack

class gdsfactory.technology.LayerStack(*, layers: dict[str, ~gdsfactory.technology.layer_stack.LayerLevel] = <factory>)

For simulation and 3D rendering. Captures design intent of the chip layers after fabrication.

Parameters:

layers – dict of layer_levels.

__init__(**data: Any) → None

Add LayerLevels automatically for subclassed LayerStacks.
