Description

Technical Field

[0001] The present application relates to the technical field of semiconductor tail gas treatment, and in particular to an integrated tail gas treatment system with a gas leakage detection function. Background Art

[0002] The semiconductor industry is one of the important sub-industries of the electronic information manufacturing industry. The semiconductor industry requires the use of a large amount of acid, alkali, organic solvents and a variety of special gases in processes such as cleaning, photolithography, degumming and drying. The entire production process will produce a large amount of toxic substances, acidic waste gas, alkaline waste gas, organic waste gas, etc.

[0003] The toxic and harmful substances and waste gas generated in this process are strictly prohibited from being discharged directly into the atmosphere without treatment. Relevant tail gas treatment must be carried out. The treated tail gas can only be discharged into the atmosphere after meeting environmental protection requirements. Under normal circumstances, the toxic and harmful substances and waste gas generated by the semiconductor industry are collected and treated in a classified and closed manner. The treatment system includes local treatment at the machine end and central treatment system at the factory end. For example, in the processes such as thermal oxidation, CVD, dry etching, and ion implantation, characteristic gases such as silane, arsine, phosphine, perfluorocarbons, halogen-containing gases and other toxic and high-boiling-point waste gases are generated, which need to be pre-treated by the local scrubber first, and then centrally treated by the central treatment system at the factory end.

[0004] The existing local scrubber tail gas treatment device is usually set up in the lower layer of the semiconductor process equipment. The pump body pumps the tail gas from the semiconductor process equipment space to the tail gas treatment device. The tail gas treated by the tail gas treatment device is finally sent to the central processing system for centralized treatment. In the prior art, many tail gas treatment devices and many pump bodies are set up in the same large space. In this setting, once a gas leak occurs, the gas will quickly diffuse into the space, requiring large-scale detection. The location of the gas leak cannot be found in time, and the equipment cannot be repaired in time. In serious cases, it may cause fire, explosion, and poisoning of personnel. Utility Model Content

[0029] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily.

[0030] The semiconductor industry is one of the important sub-industries of the electronic information manufacturing industry. The semiconductor industry requires the use of a large amount of acid, alkali, organic solvents and a variety of special gases in processes such as cleaning, photolithography, degumming and drying. The entire production process will produce a large amount of toxic substances, acidic waste gas, alkaline waste gas, organic waste gas, etc.

[0031] The toxic and harmful substances and waste gas generated in this process are strictly prohibited from being discharged directly into the atmosphere without treatment. Relevant tail gas treatment must be carried out. The treated tail gas can only be discharged into the atmosphere after meeting environmental protection requirements. Under normal circumstances, the toxic and harmful substances and waste gas generated by the semiconductor industry are collected and treated in a classified and closed manner. The treatment system includes local treatment at the machine end and central treatment system at the factory end. For example, in the processes such as thermal oxidation, CVD, dry etching, and ion implantation, characteristic gases such as silane, arsine, phosphine, perfluorocarbons, halogen-containing gases and other toxic and high-boiling-point waste gases are generated, which need to be pre-treated by the local scrubber first, and then centrally treated by the central treatment system at the factory end.

[0032] The existing local scrubber tail gas treatment device is usually set up in the lower layer of the semiconductor process equipment. The pump body pumps the tail gas from the semiconductor process equipment space to the tail gas treatment device. The tail gas treated by the tail gas treatment device is finally sent to the central processing system for centralized treatment. In the prior art, many tail gas treatment devices and many pump bodies are set up in the same large space. In this setting, once a gas leak occurs, the gas will quickly diffuse into the space, requiring large-scale detection. The location of the gas leak cannot be found in time, and the equipment cannot be repaired in time. In serious cases, it may cause fire, explosion, and poisoning of personnel.

[0033] The acoustic imaging detection device is based on microphone array measurement technology. By measuring the signal phase difference of sound waves reaching each microphone in a certain space, the position of the sound source is determined according to the phased array principle, the amplitude of the sound source is measured, and the distribution of the sound source in space is displayed in the form of an image, that is, a spatial sound field distribution cloud map - an acoustic image is obtained, in which the color and brightness of the image represent the strength, and the position of the pipeline leak can be determined. This application uses acoustic imaging detection technology to detect the location of gas leakage.

[0034] Based on this, an exemplary embodiment of the present application provides an integrated exhaust gas treatment system with a gas leakage detection function, in which the exhaust gas treatment module and the dry pump treatment module are integrated into one, and the exhaust gas treatment module and the dry pump treatment module are connected through a connecting pipeline system, and a gas leakage detection device is arranged in the dry pump processing module. In this way, the gas leakage detection device can detect in real time whether there is a gas leakage in the pipeline and locate the position of the gas leakage. Once a gas leakage is detected, an alarm can be issued in time, and the leakage position can be inspected and repaired in time to prevent major losses caused by large-scale gas leakage.

[0035] An exemplary embodiment of the present application provides an integrated exhaust gas treatment system, such as Figures 1 to 4As shown, the integrated exhaust gas treatment system includes a dry pump treatment module 10, an exhaust gas treatment module 20, and a connecting pipe system 30 connecting the dry pump treatment module 10 and the exhaust gas treatment module 20; the exhaust gas is transported from the dry pump treatment module 10 to the exhaust gas treatment module 20 through the connecting pipe system 30, and the exhaust gas after being treated by the exhaust gas treatment module 20 is subsequently treated by the central processing system. The dry pump treatment module 10 includes a first dry pump treatment system 101 and a second dry pump treatment system 102 arranged horizontally; the exhaust gas treatment module 20 includes a first exhaust gas treatment device 201 arranged on one side of the first dry pump treatment system 101 and a second exhaust gas treatment device 202 arranged on one side of the second dry pump treatment system 102. The gas leakage detection device 50 is arranged in the first dry pump treatment system 101 and the second dry pump treatment system 102, and the gas leakage detection device 50 includes an acoustic imaging detection device and a telescopic rotating bracket assembly 501, and the acoustic imaging detection device can use an existing acoustic imaging detection device on the market. Once a gas leak is detected in the system, the gas leak detection device 50 can promptly detect the location of the gas leak and issue an alarm so that the leak location can be promptly inspected and repaired to prevent major losses caused by a large amount of gas leakage.

[0036] Among them, the first dry pump treatment system 101 and the second dry pump treatment system 102 can work at the same time; or, the first dry pump treatment system 101 is a dry pump treatment system in normal working state, and the second dry pump treatment system 102 is a standby dry pump treatment system. When a leakage occurs, the second dry pump treatment system 102 is started; of course, the second dry pump treatment system 102 can also be a dry pump treatment system in normal working state, and the first dry pump treatment system 101 is a standby dry pump treatment system. The first exhaust gas treatment device 201 and the second exhaust gas treatment device 202 can adopt the existing combustion exhaust gas treatment devices on the market, and one of the first exhaust gas treatment device 201 and the second exhaust gas treatment device 202 is an exhaust gas treatment device in normal working state, and the other is a standby exhaust gas treatment device; preferably, the first exhaust gas treatment device 201 is an exhaust gas treatment device in normal working state, and the second exhaust gas treatment device 202 is a standby exhaust gas treatment device. The integrated exhaust gas treatment system integrates a dry pump treatment module 10 and an exhaust gas treatment module 20. The system has a high degree of integration and occupies a small space. The length of the pipeline connecting the pipeline system 30 is greatly reduced, thereby reducing the risk of exhaust gas leakage. At the same time, a backup dry pump treatment system and an exhaust gas treatment system are provided. When a gas leakage occurs, the backup dry pump treatment system and the exhaust gas treatment system can be activated to prevent the gas leakage from causing the equipment to be shut down for maintenance, affecting production, and reducing production efficiency.

[0037] The first dry pump processing system 101 includes a first dry pump device 1011 and a second dry pump device 1012 arranged vertically; the second dry pump processing system 102 includes a third dry pump device 1021 and a fourth dry pump device 1022 arranged vertically; the first dry pump device 1011 is arranged in the first chamber 1013, the second dry pump device 1012 is arranged in the second chamber 1014, the third dry pump device 1021 is arranged in the third chamber 1023, and the fourth dry pump device 1022 is arranged in the fourth chamber 1024; the first chamber 1013 and the second chamber 1014 are interconnected; the third chamber 1023 and the fourth chamber 1024 are interconnected. The first chamber 1013, the second chamber 1014 and the third chamber 1023, the fourth chamber 1024 are relatively sealed, and sealing rings are provided at the connection between each chamber and each pipeline for sealing.

[0038] The first tail gas treatment device 201 is disposed in the fifth chamber 2011, and the second tail gas treatment device 202 is disposed in the sixth chamber 2021. The fifth chamber 2011 is relatively sealed from the first chamber 1013 and the second chamber 1014, and the sixth chamber 2021 is relatively sealed from the third chamber 1023 and the fourth chamber 1024 to prevent leaked gas from flowing into the entire system.

[0039] A gas concentration detection device 40 is provided on the top of the first chamber 1013, the third chamber 1023, the fifth chamber 2011 and the sixth chamber 2021. The gas concentration detection device 40 may be an existing gas concentration detection device 40 on the market, for example, an electrochemical gas concentration detector or an infrared gas concentration detector. When a gas leak occurs in the first chamber 1013, the second chamber 1014, the third chamber 1023, the fourth chamber 1024, the fifth chamber 2011 and the sixth chamber 2021, the leaked gas will contact the gas concentration detection device 40 through the pipeline, and the gas concentration detection device 40 may trigger an alarm system to remind the staff that a gas leak occurs in the system, so as to timely inspect and maintain the system.

[0040] The first chamber 1013 and the second chamber 1014, the third chamber 1023 and the fourth chamber 1024, the fifth chamber 2011 and the sixth chamber 2021 are relatively sealed, so that it can be accurately detected which chamber's pipeline has a leak, which facilitates the investigation of the leak location, so as to carry out maintenance in time and reduce the risk of gas leakage.

[0041] The connecting pipe system 30 includes a first connecting pipe assembly 301 connected to the first dry pump device 1011, a second connecting pipe assembly 302 connected to the second dry pump device 1012, a third connecting pipe assembly 303 connected to the third dry pump device 1021, and a fourth connecting pipe assembly 304 connected to the fourth dry pump device 1022; the first connecting pipe assembly 301 connects the first dry pump device 1011, the first exhaust gas treatment equipment 201 and the second exhaust gas treatment equipment 202; the second connecting pipe assembly 302 connects the second dry pump device 1012, the first exhaust gas treatment equipment 201 and the second exhaust gas treatment equipment 202; the third connecting pipe assembly 303 connects the third dry pump device 1021, the first exhaust gas treatment equipment 201 and the second exhaust gas treatment equipment 202; the fourth connecting pipe assembly 304 connects the fourth dry pump device 1022, the first exhaust gas treatment equipment 201 and the second exhaust gas treatment equipment 202.

[0042] like Figure 3 As shown, the first dry pump device 1011 includes an intake pipe 1011a, a first dry pump 1011b, and an intake flow control valve 1011c; the intake flow control valve 1011c is arranged at the intake end of the intake pipe 1011a, and the intake pipe 1011a is connected to the intake flow control valve 1011c and the first dry pump 1011b. Based on the same principle, the second dry pump device 1012 includes an intake pipe 1011a, a second dry pump, and an intake flow control valve 1011c, the third dry pump device 1021 includes an intake pipe 1011a, a third dry pump, and an intake flow control valve 1011c, and the fourth dry pump device 1022 includes an intake pipe 1011a, a fourth dry pump, and an intake flow control valve 1011c.

[0043] The first connecting pipe assembly 301 includes a first connecting pipe 3011, a second connecting pipe 3013, a third connecting pipe 3014 and a bypass valve 3012; the first connecting pipe 3011 connects the first dry pump 1011b and the bypass valve 3012, the second connecting pipe 3013 connects the bypass valve 3012 and the first exhaust gas treatment device 201, and the third connecting pipe 3014 connects the bypass valve 3012 and the second exhaust gas treatment device 202. Based on the same principle, the second connecting pipe assembly 302, the third connecting pipe assembly 303 and the fourth connecting pipe assembly 304 all include the first connecting pipe 3011, the second connecting pipe 3013, the third connecting pipe 3014 and the bypass valve 3012, and the directions of the pipes in different chambers are slightly different.

[0044] In one embodiment, if Figure 1As shown, a gas leakage detection device 50 is provided in the first chamber 1013, the second chamber 1014, the third chamber 1023 and the fourth chamber 1024. During normal operation, the first exhaust gas treatment device 201 is in working state, and the second exhaust gas treatment device 202 is a standby exhaust gas treatment device. During normal operation, the second exhaust gas treatment device 202 does not work. At this time, under the action of the bypass valve 3012, the exhaust gas is sucked into the first dry pump 1011b, the second dry pump, the third dry pump and the fourth dry pump from the intake pipe 1011a, and then enters the first exhaust gas treatment device 201 through the second connecting pipe 3013. After being processed by the first exhaust gas treatment device 201, it enters the central processing system for subsequent processing.

[0045] The gas leakage detection device 50 can detect in real time whether there is any leakage of gas in the pipelines in the first chamber 1013, the second chamber 1014, the third chamber 1023 and the fourth chamber 1024. Once a gas leakage is found, the gas leakage detection device 50 can trigger the alarm system in time, and the control system can control the intake flow control valve 1011c and the bypass valve 3012 in time according to the location of the leakage to keep the entire system in a stable working state. For example, assuming that the gas leakage detection device 50 detects a gas leak on the first connecting pipe 3011 in the first connecting pipe assembly 301, at this time, the control system can control the closing of the intake flow control valve 1011c of the first dry pump device 1011. At this time, the first dry pump device 1011 does not work and waits for maintenance by the staff. The second dry pump device 1012, the third dry pump device 1021 and the fourth dry pump device 1022 continue to work. The control system can also adjust the intake flow control valve 1011c of the second dry pump device 1012, the third dry pump device 1021 and the fourth dry pump device 1022 to maintain the total intake flow within a preset range. Not only will the gas leakage not cause downtime maintenance and affect production, but the intake flow of the entire system can be maintained within a stable working range by adjusting the intake flow, and the production time will not be extended.

[0046] Exemplarily, assuming that the gas leakage detection device 50 detects that there is leakage in the first connecting pipe assembly 301 and the second connecting pipe 3013 in the second connecting pipe assembly 302 at the same time, at this time, in order to maintain a stable total intake air flow, the control system can control the bypass valve 3012 to allow the gas to flow from the first dry pump, the second dry pump, the third dry pump, and the fourth dry pump into the third connecting pipe 3014, and then into the second exhaust gas treatment equipment 202. At this time, the second exhaust gas treatment equipment 202 is enabled, and the first exhaust gas treatment equipment 201 is turned off. The second connecting pipe 3013 in the first connecting pipe assembly 301 and the second connecting pipe 302 can be inspected and maintained, and the entire system will not be shut down due to pipeline gas leakage, and production will not be affected.

[0047] The telescopic rotating bracket assembly 501 is arranged on the side wall of the first chamber 1013 or the second chamber 1014 or the third chamber 1023 or the fourth chamber 1024, and the acoustic imaging detection device is arranged on the telescopic rotating bracket assembly 501. Preferably, the first chamber 1013, the second chamber 1014, the third chamber 1023 and the fourth chamber 1024 are all provided with a gas leakage detection device 50, which can respectively detect the gas leakage of the pipelines in the first chamber 1013, the second chamber 1014, the third chamber 1023 and the fourth chamber 1024, and timely transmit the leakage information of the pipelines to the control system, so that the control system can take corresponding control in time to reduce the leakage of gas and reduce the risk of gas leakage.

[0048] like Figure 4 As shown, the telescopic rotating bracket assembly 501 includes a first driving unit 5011 arranged on the side wall, the first driving unit 5011 can be a motor, and the output end of the first driving unit 5011 is connected to the driving gear 5012 in a transmission manner; an electric push rod 5013 is also arranged below the first driving unit 5011; a passive gear 5014 is arranged on the electric push rod 5013, and the passive gear 5014 is meshed with the driving gear 5012 for transmission; one end of the electric push rod 5013 is rotatably arranged on the side wall through a bearing 5015, and a fixed bracket 5016 for fixing the acoustic imaging detection device is arranged on the other end. In this way, the first driving unit 5011 can drive the driving gear 5012 and drive the passive gear 5014 and the electric push rod 5013 to rotate, thereby driving the fixed bracket 5016 and the acoustic imaging detection device to rotate, so as to achieve all-round detection of each room space.

[0049] Exemplarily, the fixed bracket 5016 includes a hollow tubular portion 5016a sleeved on the electric push rod 5013, and a plurality of support rods are evenly arranged on the hollow tubular portion 5016a, and an acoustic imaging detection device is provided at the end of the support rod.

[0050] like Figure 5 As shown, in one embodiment, the fixed support 5016 includes a first support rod 5016b, a second support rod 5016c and a third support rod 5016d, the first support rod 5016b is provided with a first acoustic imaging detection device 5021, the second support rod 5016c is provided with a second acoustic imaging detection device 5022, and the third support rod 5016d is provided with a third acoustic imaging detection device 5023, and the detection directions of the first acoustic imaging detection device 5021, the second acoustic imaging detection device 5022 and the third acoustic imaging detection device 5023 are arranged at a preset angle. Preferably, as Figure 5As shown, the arrow directions in the figure indicate the detection directions of the first acoustic imaging detection device 5021, the second acoustic imaging detection device 5022 and the third acoustic imaging detection device 5023, and each detection direction is set at an angle of 120°. Since the lens of the acoustic imaging detection device has a certain field of view angle, for example, a field of view angle of 120°, when the first driving unit 5011 drives the fixed bracket 5016 and drives the first acoustic imaging detection device 5021, the second acoustic imaging detection device 5022 and the third acoustic imaging detection device 5023 to rotate around the extension direction of the electric push rod 5013, the three acoustic imaging detection devices can realize the detection of the entire space of the first chamber 1013, the second chamber 1014, the third chamber 1023 and the fourth chamber 1024, so as to detect the pipelines in each chamber and detect the gas leakage position in real time, so as to reduce the risk caused by gas leakage in the system, perform system maintenance in time, and reduce the risk to a minimum.

[0051] When a gas leak occurs and the pipeline is to be inspected, the electric push rod 5013 can drive the fixed bracket 5016 and the acoustic imaging detection device to move toward the side walls of the first chamber 1013, the second chamber 1014, the third chamber 1023 and the fourth chamber 1024, so that the fixed bracket 5016 and the acoustic imaging detection device are close to the side walls, reserving space for the inspection of the pipeline.

[0052] In this application, the terms "comprises", "comprising" or any other variations thereof are intended to cover non-exclusive inclusion, so that an article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such article or device. In the absence of more restrictions, the elements defined by the sentence "comprising..." do not exclude the presence of other identical elements in the article or device comprising the elements.

[0053] Although the preferred embodiments of the present application have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept.
