Definitions
- the present invention relates to a vacuum processing apparatus that performs processing such as etching, Chemical Vapor Deposition (hereinafter referred to as CVD), ashing, surface modification, etc., on a workpiece using a process gas.
- processing such as etching, Chemical Vapor Deposition (hereinafter referred to as CVD), ashing, surface modification, etc.
- process gases are now lacking in the manufacture of semiconductor devices and the production of electrical devices such as liquid crystals and solar cells. It is an important industrial machine that cannot be used.
- Control of these process gases is performed by opening and closing valves called stop valves and gas valves provided downstream of the mass flow controller via a flow controller such as the mass flow controller according to the process recipe step information. It is realized by controlling.
- the process gas introduced into the processing chamber or reaction reactor is turned into plasma or reacted at a high temperature to process the material to be processed, such as etching, CVD, ashing, surface modification, diffusion, etc. Apply.
- a process gas of several cubic centimeters / minute to several liters / minute is flowed through the stop valves and gas valves that constitute these gas supply systems, and they are opened and closed according to a complicated recipe step structure, so that durability and reliability are further improved. Cleanliness is required to suppress adhesion of foreign matter to the workpiece.
- the valve has a cylinder that is operated by applying air pressure of about 0.3 MPa to 0.65 MPa to open the valve. Normally closed valves are used that close when the air supply is stopped and the air pressure in the cylinder is released. The valve is closed by the pressing force of the spring. Diaphragms and bellows are used as movable parts in the gas contact part to prevent leakage of process gas to the outside. When the device energization is turned off for safety, a normally closed type valve that closes the valve to stop the gas supply is frequently used in the gas supply system.
- An electromagnetic valve (solenoid valve) is used to supply an air signal for opening these valves.
- An air signal is generated according to the electrical signal On / Off.
- process gases that are subject to control include gases that are flammable and flammable, as well as toxic and corrosive. Various interlock functions are available to safely use, mix, and react these gases. It is designed so that it can be safely processed and processed by holding the device.
- Patent Document 1 As an example of providing an interlock function in a circuit for controlling air pressure for controlling valve opening / closing, there is a means disclosed in Patent Document 1.
- Double interlocking hardware is usually required as a foolproof function for interlocks that prevent malfunctions.
- the opening and closing operation of these process gas valves using an electrical relay circuit, etc., according to the pressure signal and the circuit studied in advance, the mutual opening and closing operation between different valves is controlled, abnormal reaction, It is devised to prevent gas leakage and gas source contamination (mixing with other gases).
- the software that controls the device is also designed to avoid dangerous operations that have been entered incorrectly or intentionally based on the interlock concept, but in many cases the soft interlock has a foolproof function. As insufficient. For this reason, in addition to an electrical interlock, yet another device is required.
- One of the methods is to immediately stop the gas supply when an abnormality occurs or when an abnormal operation is instructed.
- the process gas valve When the gas leak sensor provided in the room detects gas, for example, the process gas valve is closed by electrically cutting off the supply to the above-described electromagnetic valve so that no air signal is generated. At the same time, by having the function of cutting off the supply of air to the solenoid valve as energy, we try to eliminate the energy itself for opening the valve from the pipe. Thus, the supply of process gas can be stopped electrically and mechanically.
- the signal of this vacuum gauge is used for electrical interlocking of the combustible gas valve opening and the combustion supporting gas valve opening. Furthermore, in an apparatus using a corrosive gas (for example, an etching apparatus), in order to reduce the process gas piping exposed to the atmosphere for maintenance as much as possible and suppress the generation of foreign matter such as rust, a processing chamber or a reaction reactor ( A final stage valve is provided near the chamber.
- a corrosive gas for example, an etching apparatus
- a final stage valve is provided near the chamber.
- the gas from the nitrogen gas source with low reaction rate is used to fill the piping with safe gas.
- An N2 purge line is provided upstream of the mass flow controller.
- a check valve is usually provided to prevent the process gas from flowing back into the piping of the N2 purge line, and the N2 purge pressure is set higher than the pressure of the process gas to prevent backflow.
- an interlock is required to prevent the purge N2 gas supply valve and the process gas supply source valve from opening simultaneously.
- a highly reliable valve is used so that the probability that the two valves fail simultaneously is extremely low. Therefore, as a foolproof function, it is necessary to separately provide an interlock that prevents the two valves from being opened simultaneously, in addition to an electrical interlock that is not opened unless a vacuum is applied.
- the gas is supplied to the downstream side of the normal gas line and the exhaust gas flowing through the final stage valve so as to come into contact with the object to be processed in the processing chamber or reaction reactor (chamber) for processing.
- Some devices have a line to throw away.
- the gas piping is connected before and after the compressible turbomolecular pump. For example, if the valve for the final stage and the piping for discarding the gas are simultaneously opened, the compression downstream of the turbomolecular pump is performed. The gas thus made flows back through the gas pipe from the final stage valve into the processing chamber or reaction reactor (chamber).
- the present invention provides a vacuum processing apparatus including a gas supply means having a hard interlock of a pair of gas valves.
- the present invention relates to a vacuum processing apparatus including a gas supply unit that supplies a gas for performing vacuum processing to a processing chamber in which the vacuum processing is performed using a normally closed type air-driven valve.

- the valve V2 is a valve at the outlet (downstream) of the flammable gas MFC.
- the valve V11 is a process gas supply (upstream) valve for combustible gas
- the valve V21 is a process gas supply (upstream) valve for combustible gas.
- Downstream of each MFC is an N2 purge valve V12 for supplying a combustible gas purge N2 and an N2 purge valve V22 for supplying a combustion-supporting gas purge N2, respectively. It is connected with the process gas supply (upstream) valve.

- N12 purge valve V12 the combination of valve V21, which is a process gas supply (upstream) valve for combustion-supporting gas, and valve V22 for N2 purge It is.
- process gas supply (upstream) valves V11 and V21 do not generate gas turbidity due to the gas flowing downstream, so that either the final stage valve V0 or the waste gas valve V00 is used. It must be possible to open it only in the open state.
- FIG. 2 is a control system diagram of the air signal of the vacuum processing apparatus shown in FIG.
- the air supply line 15 is supplied with pressurized air from an air source.
- the air discharge line 16 discharges air in the cylinder after driving the valve from this line.
- the solenoid coil excitation elements S0 to S22 are solenoid coil excitation elements for generating air for opening the process gas valves.
- each solenoid coil (indicated by the same number) is excited and pressurized by an air signal (air supply) to be opened.
- the 3-position spring return center exhaust type 5-port solenoid valve 21, 24, and 25 is not supplied with air and is in a state of air bleeding through the air discharge line 16.
- the 2-position spring return type solenoid valves 22 and 23 are a combustible gas MFC outlet (downstream) valve V1 and a combustion-supporting gas MFC outlet (downstream), respectively, according to an opening command for exciting the solenoid coil excitation elements S1 and S2.

- N2 purge valves V12 and V22 which are nitrogen purge lines, need to be purged during replacement of AA gas supply system, such as valves and mass flow controllers, and maintenance work. Therefore, even if neither the final stage valve V0 nor the waste gas valve V00 is open, it will be open and N2 purge must be possible, so the N2 purge directly without going through the pilot valve using the pilot air signal line 17
