    FITOK Integrated Gas System, a device specifically used for gas control in the semiconductor industry....

  • Integrated Gas System is a modular system used for gas control in semiconductor industry. With the advance of semiconductor process technology, higher requirements for gas control system arise.


    FITOK integrated gas system adopts surface mount components conforming to SEMI standard for modular design, which makes installation and maintenance simpler while reducing the size of the system.

    Single Flow Path  System



    ◆Modular design-shorten design time

    According to the customer's PID diagram, the design can be completed by installing standard substrate, valves (diaphragm valves, check valves, regulators), flowmeters, filters, pressure sensors and other components on the  panel.

    ◆Surface mounting-easy for installation and maintenance

    All components are surface mounted in accordance with SEMI standard (1.125 ''W-seal), and installation and later maintenance can be completed with simple tools.


    The size is about 1/3 the traditional panel, and the corresponding flow path size is also reduced for better contamination control.

    ◆316LVV material, electropolishing process and orbital welding

    The wetted components are all 316LVIM-VAR austenitic stainless steel, the flow paths are all electrolytically polished (Ra0.13), and the fittings are all orbital welded.


    W-seal between the components and the substrate, the sealing faces are independent of components receiving external forces, thus achieving the optimal sealing effect.

    At a glance

    Vacuum generators are devices designed to evacuate the gas lines of residue gas by creating a vacuum. With a minimum source Nitrogen pressure of 70 psig, FITOK vacuum generators can generate a 60 Torr vacuum, thus greatly improving the purging efficiency.

    ◎ All-welded design

    ◎ Inner surface roughness of Ra 20 μin. (0.51 μm)

    ◎ 100% tested for Helium leakage


    Technical Data

      Ultimate Vaccum Pressure

      60 Torr (-93.3 kPa)

      Gas Pressure at Ultimate

      70 psig (4.8 bar)

      Gas Flow at Ultimate

      67 l/min

      Max. Working Pressure

      132 psig (10 bar)

      Working Temperature

      32~302°F (0~150°C)


    How it works

    Supply the vacuum generator with gas at inlet. The constriction of nozzle causes the gas flow to accelerate. After exiting the nozzle, the accelerated gas expands and flows through the disffuser into the outlet port. In the process, a vacuum is created in the disffusion chamber, which sucks the residue gas from the gas lines through the vacuum port.
