GDS Import

The GDS import tab (Figure 68) provides functionality to import a GDS file as a field.

We recommend to use KLayout for creating and editing GDS files.

Limitations

  • Maximum number of layers: 10

  • Maximum rasterization dimension: 5,000 x 5,000 pixels

    Increasing the step size reduces the rasterization dimension.

  • The current version does not rasterize GDS Path elements accurately

    Convert GDS Path elements to GDS Boundary elements in KLayout.

    KLayout > Edit > Selection > Merge Shapes

  • GDS Node and GDS Text elements are not rasterized

Open GDS File: Select and load a GDS file

Field Size: Figure 69 shows the field size parameters

Figure 69 Field Size Parameters

Lock Aspect Ratio: Enforce equal dX and dY

dX (nm): X-spacing between adjacent tip indentations

dY (nm): Y-spacing between adjacent tip indentations

X (µm): X-size of the field

Derived from the imported GDS X-size.

Y (µm): Y-size of the field

Derived from the imported GDS Y-size.

X (px): X-dimension of the field

Derived from dx (nm) and the imported GDS X-size.

Y (px): Y-dimension of the field

Derived from dY (nm) and the imported GDS Y-size.

Orientation (°): Orientation of the write field relative to the piezo scanner (θ)

Field Depth: Each layer in the GDS file is assigned a target depth

{Layer Id : depth (nm), ...}: Input string format

Assign 0 depth to exclude a layer.
