Klayout - Layout Viewer And Editor Free Downloads - 2000 Shareware periodically updates software information and pricing of Klayout - Layout Viewer And Editor from the publisher, so some information may be slightly out-of-date. You should confirm all information before relying on it. Suretrak 3.0 windows 10. Thank you for using our Mac software library. Unfortunately, there is no direct download for the Mac version of KLayout. To download the product, proceed to the developer's site via the link below. FDMLib cannot ensure the security of software that is hosted on third-party sites. For the first topic, luckly KLayout has a concept similar to the devicePixelRatio: the 'resolution'. The idea is to define a drawing unit - a 'pixel' - and indicate that the canvas has a smaller physical pixel size. The rulers and annotations - whose width is one 'pixel' - get painted with n.

Klayout Macro
KLayout
A free, open-source, and fast/simple CAD tool for mask/reticle layout. Download at klayout.de.
- Available on Windows, Mac or *Nix.
- Easily scriptable with Python or Ruby, with decent tutorials.
- Fast and very effective viewing of layer overlay, overlay multiple files, cell hierarchy etc.
- ‘Before’ starting your design, set the Layout Properties > Database Unit to something small eg. 0.0001 µm (0.1nm).
- Turn on the display of the Origin (0,0) in Preferences > Display > Background > Axis = choose an option apart from the default 'invisible', eg. 'Lines with Ticks'.
- How to draw circles. You have to draw a square, and then apply the Edit>Selection>Round Corners function with Outer Corner Radius = the desired circle radius. This is for compatibility, because GDS files do not have a 'circle' primitive built-in, so instead it creates a polygon. Make sure you include enough polygon points, eg. 100. See the forum help pages on this for more info.
CAD Design Tips
It is highly recommended that you understand and use the concept of 'Cells' in your design. This circumvents many problems with enormous file sizes (due to huge numbers of identical polygons), and if used properly, helps tremendously with programming the Stepper lithography machines. Links to documentation below:
Klayout For Mac
- Create a new cell, and instancing that cell: KLayout Docs : Creating a Cell instance
- Viewing only some levels of the heirachy, to prevent drawing all objects: KLayout Docs: Viewing Cell Heirarchy
OASIS files tend to be much smaller than GDS files, and they also save the Layer Names (not just number). Alternatively, in KLayout the function File > Save Session will save the entire view including layer styles and window/zoom locations will be saved. You can share this file, as the entire design file is embedded within it, but it may not be as robust between KLayout versions.
Example CAD File
Here is an example CAD file, showing the use of Layers and Cells, designed in KLayout. The device is fictional, for illustrative purposes only.
- CAD_Tutorial_for_ASML_Reticle_v1.OAS (Demis D. John)
- Cell 'Device_Layout' shows a single device, with each Layer overlaid as it would be in a fabricated device. Each Layer (eg. a 'process step' such as Mesa etch, Pad Metal etc.) is placed into it's own Cell.
'Device_Layout' Cell showing as the 'top cell'
- Every Cell's Origin (0,0) lies on top of one another in the final Device_Layout.
- One way this can be accomplished is by selecting the objects/polygons you want to make into a new Cell, then use the function Edit >Selection > Make Cell, and uncheck the 'Put Origin at..' checkbox, so the new Cell maintains the same origin as the original view.
- The Cell 'Reticle_Layout' can be exported by itself (right-click the Cell name), for sending to the photomask manufacturer.
- Here is and example GDS file (download) for submission to the photomask manufacturer, with all objects moved to a single Layer.
- See the ASML Mask Making Guidelines page for an example of how to program this Reticle into an ASML Stepper job.
General Calculators
- Anaconda Python
- A free Matlab-like IDE and GUI, using the Python language. The Spyder interface is modeled after Matlab.

- Octave Online Interpreter (online-utility.org)
- A Matlab-like command-line interface, powered by Python Octave.
- Wolfram Alpha
- A versatile online interpreter/calculator, allowing calculations such as 'Volume of 1.5g of Silicon', 'melting point of SiO2' or '520°C in Fahrenheit'.
Python Scripts
These scripts are best run in the Spyder IDE, which is easily installed via Anaconda, Python(X,Y), or by directly compiling Spyder using a command-line package manager.
