To deposit photo resists, the Nanolab is equipped with a solar-semi EL S 200 BM spin-coating module. The coater can handle

  • wafers up to 8" or
  • samples up to 6" × 6".

Process step times range from 0.5 s to 999.9 s. The speed as well as the the acceleration of the rotary plate are freely programmable:

  • speed starting at 100 rpm up to 6000 rpm and
  • acceleration starting at 1 rpm/s up to 6000 rpm/s.

In total, 40 recipes with 8 steps each can be saved on the internal memory.
