Level for 3D LayerStack.

Parameters:
  • name – layer name.

  • layer – (GDSII Layer number, GDSII datatype).

  • thickness – layer thickness in um.

  • thickness_tolerance – layer thickness tolerance in um.

  • zmin – height position where material starts in um.

  • zmin_tolerance – layer height tolerance in um.

  • material – material name.

  • sidewall_angle – in degrees with respect to normal.

  • sidewall_angle_tolerance – in degrees.

  • width_to_z – if sidewall_angle, relative z-position (0 –> zmin, 1 –> zmin + thickness).

  • z_to_bias – parametrizes shrinking/expansion of the design GDS layer when extruding from zmin (0) to zmin + thickness (1). Defaults no buffering [[0, 1], [0, 0]].

  • mesh_order – lower mesh order (1) will have priority over higher mesh order (2) in the regions where materials overlap.

  • layer_type – grow, etch, implant, or background.

  • mode – octagon, taper, round. https://gdsfactory.github.io/klayout_pyxs/DocGrow.html

  • into – etch into another layer. https://gdsfactory.github.io/klayout_pyxs/DocGrow.html

  • resistivity – for metals.

  • bias – in um for the etch. Can be a single number or 2 numbers (bias_x, bias_y)

  • derived_layer – Optional derived layer, used for layer_type=’etch’ to define the slab.

  • info – simulation_info and other types of metadata.

  • background_doping_concentration – uniform base doping level in the material (cm-3)

  • background_doping_ion – uniform base doping ion in the material

  • orientation – of the wafer (Miller indices of the plane)

__init__(**data: Any) None#

Create a new model by parsing and validating input data from keyword arguments.

Raises [ValidationError][pydantic_core.ValidationError] if the input data cannot be validated to form a valid model.

self is explicitly positional-only to allow self as a field name.

Methods

__init__(**data)

Create a new model by parsing and validating input data from keyword arguments.
