- Upgradeable to plasma, in the field.
- Warm-walled aluminum chamber with heated sample holder from 40 – 400°C
- 3 organometallic precursors can be heated to 185°C and an additional one at standard conditions*
- Up to 4 oxidant/reductant sources each with ultrafast MFCs (2 standard)
- High temperature compatible fast pulsing ALD valves with an ultrafast MFC for
integrated inert gas purge - High exposure available with static processing mode
-
* Upgradeable to 4, all heated to 185°C.
SPECIFICATION
- Substrate temperatures from RT to 400°C ± 1 °C; Precursor temperatures from RT to 185°C ± 2°C (w/ heating jacket)

FACILITIES
- For detailed instructions see our presentation and video instructions: “AT650T Installation and Start-up“
- N2 purge gas should be >99.9995% with a shutoff valve (regulated to 10 – 30 psi, metal sealed).
- Input line is 1/4 female VCR compression fitting
- Attach > 99.9995% nitrogen (UHP) purge gas via 1/4″ metal line to the 1/4″ compression fitting on back
- Attach 90-110 psi CDA (clean dry air) via 1/4″ polyethylene tubing or metal line to the other 1/4″ compression fitting marked CDA (Clean Dry Air)
- Min 19.5cfm wet pump (**PTFE vacuum fluid (like Fomblin) required) (Dry pumps is optional)
- NW40 (1.5″) connection and also exhaust line (with > 5cfm draw)
- Greater than 1 meter should use NW50 exhaust line
- Precursor’s attach via female VCR elbows (always use new gaskets).
- Elbow: 1/4″ gasket first (with gloves on)
- For precursor attachment please refer to “AT650T Tool and Software Operation”
