Final check
Make sure the bar
separating the front and the back
electrode is
clear. No part of your pattern should
cross it.
Are any parts of your
pattern isolated? If so go to step
11.
Because
your pattern is only 1” square, you can put many on one sheet. It
is a good idea to copy our mask pattern
several times so that you have extra.
Test print you mask
on paper
You will use a laser
printer to generate your mask
by printing onto
transparency film.
Because transparency
film does not grow on trees
we will first make a
test print on paper.
It is best to perform
the test print on the SAME printer
you will use for the
transparency.
Print your mask on transparency film.
Inspect you Finished
Mask
If you find defects in
the black image
use a Sharpie marker to
cover the
unwanted clear
areas.
When you are sissified
with your mask
your are ready for the
photolithography.
