forever.

Subject: [mems-talk] Regarding Glass lithography

Hi all!
    I am trying to make one-dimensional groove pattern over the glass
surface with a width and depth ranging from 50micron to 200 micron. I
laminated dry photoresist over the glass surface and prepared the
pattern in the glass surface. Photoresist is not staying more than 1
minute if i put it in dilute HF. And also I read in this site that I can
use Chromium as a sacrificial layer. But I don't have chromium with me.
Can you suggest some other material as a sacrificial layer ? Whether I
have to coat my sacrificial layer before or after the photoresist ?
Please give some idea to overcome this issue.
          Thanks!
                                  With regards,
                                    R.Kannan
