Definitions
- the present invention relates to a vacuum device, and more particularly to a small vacuum device that consumes less power of a vacuum pump.
- Vacuum devices are used in many industrial fields, including the semiconductor and liquid crystal display manufacturing fields. Especially in the field of semiconductor and liquid crystal display manufacturing, most processes such as film formation, etching and etching are performed under reduced pressure atmosphere in vacuum equipment.
- a vacuum pump is used to maintain the inside of a vacuum vessel for performing a process, measurement, or the like in a vacuum or reduced pressure.
- pumps of the scraping type tend to have a higher evacuation speed and a lower allowable back pressure as the ultimate vacuum degree is higher.
- the vacuum pump ultimate vacuum is operating at high 1.
- These pumps have a high pumping speed even with small pumps, but have an extremely low allowable back pressure of 133 Pa (lTorr) or less.
- the present invention provides a vacuum container having a gas inlet and an exhaust port, a gas supply system for introducing a desired gas from the gas inlet into the vacuum container.
- a vacuum device provided with an exhaust system for keeping the vacuum vessel ⁇ at a reduced pressure, wherein the exhaust system has a plurality of vacuum pumps connected in multiple stages in series, and the exhaust port pressure of the final stage vacuum pump is substantially large. Atmospheric pressure is realized, and a vacuum apparatus is realized in which the last-stage vacuum pump or, if necessary, the middle-stage vacuum pump exhausts gas from a plurality of front-stage vacuum pumps per unit.
- FIG. 5 is a schematic diagram of an apparatus according to the fourth embodiment.
- the mechanical pump booster pump maintains the pumping speed up to a low pressure range of about 4.00 Pa (30 mTorr), while the roots pump has a significantly reduced pumping speed in the pressure range of 133.32 Pa (ITorr) or less. . Therefore, in order to obtain the required pumping speed with a roots pump, it is necessary to select a larger pump. For example, to obtain a pumping speed of 2000 L / min at 53.33 Pa (0.4 Torr), which is the allowable back pressure of a thread groove type molecular pump, a roots pump of 2400 L / min is required according to Fig. 2. I understand.
- the valve 603 of the vacuum vessel that is not performing the process is closed and the roughing pump 60 is closed.
- the rough exhaust system is added to the apparatus of the second embodiment, but the same effect can be obtained by adding the rough exhaust system to the apparatus of the first to fourth embodiments.
- the piping 604 is connected to the exhaust side of the high vacuum pump, but it may be connected directly to the vacuum vessel or to the exhaust side of the low vacuum pump. .
- exhaust gas generated after processing in a vacuum vessel contains a large amount of precipitated by-products and the like. These substances are contained in the gas phase component and the exhaust gas in the vacuum vessel, but are cooled during passage through the pipe, change into a solid phase component, and may adhere to the inside of the pipe. Such deposits may cause a decrease in the pumping performance of the vacuum pump and a failure of the device itself. Since such deposits reduce the cross-sectional area of the piping, they also include the problem of reducing the conductance of the exhaust gas, and it is desirable to take measures to prevent the deposits.
- a water-cooled truck is used as a means for removing the precipitated components in the exhaust gas.
- the heating means may be any means that can heat a portion in contact with the exhaust gas in the exhaust path to at least 90 ° C or more, and is not limited to the rubber heater of the embodiment, such as using a ceramic heater. The same is true for
