S1818 - NanoLabStaff/nanolab GitHub Wiki
Coater: Polos Spin 150
| Spin speed (rpm) | Thickness (μm) |
|---|---|
| 2000 | 2.66 |
| 4000 | 1.87 |
| 5000 | 1.68 |
| 6000 | 1.52 |
- Spin time 30s
- Ramp: 1s.
- Thickness measured after soft bake using reflectometer (robust mode, FTT gives slightly lower values).
- Lamp intensity warning on Filmetrics reflectometer in litho finger,but values were in agreement with the one in the student lab
Very uniform coating for >3000rpm.
