    Hi,

    I'd like to know if any available software for creating pattern
    (a simple pattern black and white rectangles) with a precision up to 10 micron.
    And I can print the output on normal paper with laser printing (1200 dpi).

    Thanks for any helps,
    sant
     
  2. I'd like to know if any available software for creating pattern
    Our experience with printing on slides on an HP laserjet 4 (supposedly
    1200 dpi) is that 20 um is the best resolution you can achieve, and
    with poor reproducibility. Most important is the fact that laser
    printers
    will not provide lines dark enough for lithography (some of the UV light
    will go through pinholes in the ink). We either have to give the design
    to a professional printing shop (~4 euros/sheet) or use optical
    reduction
    (using photography development equiment). Also be aware that on some
    slides,
    granular structure might affect the lithographic process and become
    apparent at a later stage.

    For the pattern generation, I use either xfig (unix) or diretly program
    in postscript for periodic patters. A colleague of mine uses CleWin
    as available at http://www.wieweb.com/ie/index.html
