| Most of the NanoLab tools (and most other microfabrication applications elsewhere!) take as input a GDSII file. This is the particular type of 2D file we almost exclusively use. These files have a number of layers, and each layer contains some number of polygons. For example, a photolithography tool like [[mla150|mla150]] might expose a pattern on a wafer everywhere there is a polygon on either of two particular wafers in a given GDSII file. | Most of the NanoLab tools (and most other microfabrication applications elsewhere!) take as input a GDSII file.

Each color represents a different layer of the GDSII file (sometimes, multiple GDSII layers are used in a single fabrication step). |

| + | Occasionally pages on this wiki may link to GDSII files. GDSII files can be large (megabytes to gigabytes), so we usually store them on [[home|Box or Google Drive]]. GDSII files can be large (megabytes to gigabytes) due to the sheer complexity of the designs they represent. | ||

| We have also created software to programmatically generate GDSII files with full electrostatic inchworm motors, etc., given only a few basic parameters. This can drastically reduce design time. | We have also created software to programmatically generate GDSII files with full electrostatic inchworm motors, etc., given only a few basic parameters.
