Define Layout¶
This section explains how to upload pattern files on the NanoFrazor.
- Select Layout from the top menu of the Main Panel.
select Field Source from the left menu.
The layout can be defined starting from bitmap or GDSII files.
Import Bitmap¶
If you wish to import a bitmap:
- Select the Image Import tab.
- Click on the Open Image File button. A dialogue opens - select the desired bitmap file. File types supported are .png, .bmp, .jpeg, and .tiff. The bitmap dimension should be less than 10,000 x 10,000 pixels.
- Adjust image if necessary (Invert Grayscale, Flip, Rotate, Interpolate).
- In the Field Size box, specify the pixel size (= indentation spacing) in X and in Y (dX (nm) and dY (nm)). The field size should be less than 60 µm x 60 µm.
- In the Field Depth box specify the field depth range (Min (nm) to Max (nm)).
- Click once on the Load image as Field 0 button. The image is loaded to the NanoFrazor as a write field.
Note
Clicking the button again creates a new field with an updated numbering, e.g. Load image as Field 1.
Note
If you tick the Exclude White Pixels box the pure white color pixels of the bitmap will not be written. This option is mainly used for single level patterns with only one desired written depth (the Min (nm) depth). If Exclude White Pixels is not ticked, the white pixels of the bitmap will be written with depth equal to Min(nm).

Import GDSII¶
If you wish to import a GDSII file:
Select the GDS Import tab.
Click on the Open GDS File button. A dialogue opens - select the desired GDSII file. The total size of the design in the GDSII file should not exceed 60 µm x 60 µm.
Specify the pixel sizes, dX (nm) and dY (nm), that will be used for the pixelization of the design.
In the Field Depth box specify the target depth for each layer. This is done by editing the string “{layer Id : depth (nm), ...}”. If the target depth for a layer is set to 0 nm, this layer will not be written at all.
