About

The three stack Tystar 8” furnace is used primarily for 3 processes. The processes are dedicated for one tube each:

1. Dry or wet oxidation of silicon
2. Dry or wet oxidation of AlGaAs (or other materials)
3. General furnace annealing

The tubes can hold up to twenty-five 8” wafers per cycle. We have boats for various wafer sizes, including pieces. The maximum temperature is 1050°C for the system. Gases used are O₂, Steam from DI-H₂O, N₂.

Under the “ambient” variable use the following:

• Wet – 0.945
• Dry – 1.298

These numbers will give accurate growth calculations.
