Hi All,
I am doing some layout which requires sharp corners of shapes on the wafer after the photolithography and etch steps. Towards this I wanted to add some small serifs (square shapes for example of 1um square) to all the corners of a drawn shape. I was wondering if anyone had worked on a script to do this, which you would be willing to share? The drawn shape may not be drawn to Manhattan rules and hence I wanted the serif to be rotated to the same angle as the corner. Any help or guidance would be much appreciated.
Thanks,
Vikas

Hi,
For Manhattan, there is a very simple solution using the DRC feature:
A generic solution would be this:
But in my example it was only partially working. I need to take a look into this.

The edge extension feature bug is fixed now (https://github.com/klayoutmatthias/klayout/issues/90) and will be released with the next minor release.
