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 blue. Your will
delete this later.
Draw your pattern
inside the rectangle.
Make sure it is black
& white. No gray.
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.
