Create a temporary guide
It is useful to make a rectangle to define the pattern area.
Add a rectangle to define your pattern area, shown in
Your will delete this later.
Draw your pattern inside the rectangle.
Make sure it is black & white.
Remember the mask will define where
acid will remove ITO
Fixing isolated areas
The pattern we want, enclose regions
of ITO which are not connected to the
front electrode contact.
We can easily fix this by drawing black lines
between the outside and the inside.
Use several lines
to insure connection.
Some may fail.
Use lines at least 1-1/2 pts wide.
Finalizing your pattern
When you are satisfied with your pattern
erase the guide rectangle from step 9.
Group all of the objects.
This helps prevent parts of your
mask from accidentally shifting.
