The following alignment marks are suggested to use on the Mask aligners for good pattern recognition. Pleased be adviced that they can be removed in KOH etching. | The following alignment marks are suggested to use on the Mask aligners for good pattern recognition.

Our standard mask supplier is [https://www.macdermidalpha.com/semiconductor-solutions/compugraphics Compugraphics]. They can provide 5" and 7" masks on soda lime glass or quartz. Minimum feature size can be 0.8µm, 1µm or 1.5µm which is reflected in the price.

If you are using L-edit to design your mask you should remember to mark the top cell as the fabrication cell; a small pink <b style="color:magenta">''f''</b> should show to the left of the cell name in the Design Navigator. | If you are using L-edit to design your mask you should remember to mark the top cell as the fabrication cell; a small pink <b style="color:magenta">''f''</b> should show to the left of the cell name in the Design Navigator. | ||
