-  - Use a piece of glass with dimensions 50*50 mm, with a thickness of 1.56 mm. You can get this at the LIS. Quarts glass is best, but regular glass will be fine. The 50*50mm is an upper boundary, larger peices will not fit into the sample holder. The 1.56mm is a lower boundary, if your glass is to thin, the clamps won't work and your class will move during the process.

   - Carefully clean the glass, avoid scratches.
   - Use the [[Z-400#manual|Z400]] to sputter 10-20 seconds (no longer!!!) of MoGe. This will prevent charge building up in the ebeam.
