Liquid source

Flexibility through easy use of multiple chemistries

Beneq’s liquid source options support the versatility and modularity of the Beneq TFS 200 research platform. With multiple liquid sources, you can run more processes simultaneously. Dedicated precursor sources and lines improve efficiency, reduce maintenance work and prevent cross-contamination.

Beneq TFS 200 can accommodate a maximum of four liquid source lines.

All of our liquid source options include

• a liquid source container (container type chosen separately)
• integration with gas delivery unit (GDU)
• standard tubing, needle valve (if chosen) and pulsing valves
• software upgrade
• testing and documentation
• commissioning by Beneq personnel

Our liquid sources are available in two different configurations

• liquid source with a single output from a vessel
• liquid source with a dual line setup (output and boosting nitrogen input)

Liquid source line with boosting functionality LS-BL

For low vapour pressure liquid precursors (BTBAS, 3DMAS, TEGA, etc.)

Includes:

• two pneumatic pulsing valves: one for purge gas, the other for chemical supply
• high precision needle valve for pulse adjustment
• orbital welded stainless steel tubing with VCR® (Swagelok) fittings
• aluminum liquid source container holder cooling cup for controlling the source temperature between +5 °C and room temperature (requires cooling water assembly, chiller or facility cooling lines)

Please note that this option does not include a precursor container.

Liquid source precursor containers LS-BL-PC/200 and LS-BL-PC/200 DOT

Additional liquid source containers.

• for water (H₂O), trimethyl aluminum (TMA), diethyl zinc (DEZ), titanium tetrachloride (TiCl₄) etc.
• volume 200 ml, maximum filling volume 150 ml*
• equipped with two separate lines with manual valves
• material: stainless steel
• LS-LS-BL-PC/200 : for H₂O, TMA, DEZ, TiCl₄ etc.
