The most important source of information is always the photoresist manufacture's data sheet (see the T: drive). There are also some good textbooks in the OSU library that cover all aspects of microfabrication: text/html 2009-11-23T13:06:31-08:00 Ethan Minot http://www.science.oregonstate.edu/~minote/wiki/doku.php?id=designcad_hints&rev=1259010391&do=diff DesignCAD product website Overview Export your DesignCAD drawing in the .dxf format. All shapes in this file must be closed polygons. For example, a rectangle drawn with the rectangle tool is a closed polygon, however, 4 individual lines that touch at 4 corners do not form a closed polygon. If necessary, you can bind together a selection of lines with the key stroke shortcut “b”, thereby creating a closed polygon. text/html 2009-11-23T11:05:58-08:00 Ethan Minot http://www.science.oregonstate.edu/~minote/wiki/doku.php?id=outreach&rev=1259003158&do=diff * Size scales in nature * Carbon nanotubes * Atomic force microscope image of a butterfly wing text/html 2009-11-20T16:51:39-08:00 Ethan Minot http://www.science.oregonstate.edu/~minote/wiki/doku.php?id=wiki:navigation&rev=1258764699&do=diff * admin * advising * AFM * device making * group meetings * lab notes * nanotube growth * optics * outreach * purchasing supplies * probe station * proteins * safety * scheduling * seminars * software * travel & conferences text/html 2009-11-20T16:24:38-08:00 Ethan Minot http://www.science.oregonstate.edu/~minote/wiki/doku.php?id=comsol&rev=1258763078&do=diff Fluid dynamics and mass transport Comsol can be used to solve the Navier-Stokes equation for an arbitrary flow geometry.

Important add-on is the wash station (dips the needle in a sonicator bath) for $2,600. When working with proteins cooling may be important ($8,000 add on). The SpotBot has excellent precision (better than 10 microns) once it finds the first spot place. The trick is this initial alignment. The smallest spotter needle gives ~ 50 micron diameter. Hydrophobic surfaces stop the spots from getting bigger. text/html 2009-11-18T15:37:39-08:00 Ethan Minot http://www.science.oregonstate.edu/~minote/wiki/doku.php?id=start&rev=1258587459&do=diff Welcome to the wiki for the Minot Research Group in the Department of Physics at Oregon State University. Group members contribute and maintain up-to-date manuals, recipes and information on many common lab questions. (Setting up a wiki like this one is relatively easy.)
