We (the Khuri-Yakub lab) spent a lot of time trying to figure out how to export data/pictures but came to a dead-end. We contacted the company who wrote the software and they confirmed that such exporting was not possible. We then spent some time trying to reverse engineer the pics from the raw-data but came to a dead-end there too b/c of the approximations that are made in the software. moe. mbadi at snf On Thu, 16 Aug 2001, Graham Milne wrote: > > > Does anyone know of either a way to get the data from the stresstest into > excel or a computer somewhere in the building that has the relevant software > AND a colour printer? > > Thanks, > > Graham > > _________________________________________________________________ > Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp > > moe. -------- Mohammed H.

The best way to export the data is just to take a printscreen, go to MS paint, and store it as a JPG so that it will fit on you disk. That's probably you best bet. If you want data files, it's a little more complicated and will not necesarily give you what you want. What the stresstester stores are values (with nonstandard units) that are proportional to instantaneous curvature (ie if you integrate them you'll get your wafer height x some constant). This is all it stores, and from there does various calculations to generate the multiple 3D graphs. If you want this you can go into your directory under the FSM directory and look for a files similar to you scan name and wafer number (ie bob001.*). Look for the file with the extension .mpm (for mappings) or .scm (for scans). If you open up these files with notepad, you'll see a table of numbers, each column representing a scan. Save the bob001.scm or bob001.mpm onto your disk and take it to Excel. There are some fudge factors and equations to get curvature, height, or stress or what have you. They'll give you the crossection of each scan line. I'm not sure how you would generate a 3D graph from that, but if you know I'd be interested to hear. I think i have the numbers/equations if you want. Also keep in mind that the stress distribution may not be accurate. I talked with the makers of the stress-tester and they weren't sure they could use a stress equation (Stoney's) with their measurements. They had a debate when they were writing our version of the software and just decided to stick it in. In their newest software release they don't have a stress option altogether. Just another thought, I don't remember if there is a print option in the FSM software, but if there is and you can install a postscript printer driver, then you can print to a postscript file, save that on disk, and export that. I don't believe that the FSM computer is connected to any network or computer.
