[0002] Wafer manufacturing needs to be carried out in a clean room, and as the process evolves, its improved line diameter has reached the level of nanometers, so in a semiconductor high-order wafer manufacturing plant, the clean room has begun to care about the concentration of extremely small gaseous molecular pollutants (AMC) in addition to filtering out particulate pollutants, wherein the gaseous molecular pollutants (AMC) include VOC organic, acid, alkali, DOPANT, etc. four substances, and it is required that gaseous molecular pollutants (AMC) must also be filtered out, so chemical filter screens are used in clean rooms to remove such gaseous molecular pollutants (AMC). However, the source of gaseous molecular pollutants (AMC) is quite extensive, and how to effectively control it becomes a very important issue.

[0003] In addition, the clean room has another source of micro-pollution in addition to the above-mentioned gaseous molecular pollutants (AMC), which is outside air (Outside Air), i.e. the surrounding atmospheric environment. The concentration of volatile organic pollutants (VOC) in outside air (Outside Air) is very low, generally less than 1000 ppb, and the total volatile organic gas (TVOC) concentration is also about <1000 ppb, which contains isopropyl alcohol, acetone, toluene, etc. Because the total volatile organic gas (TVOC) concentration is relatively low, it does not exceed the hazardous or acceptable standards set by international WHO or the Institute of Occupational Health, so it has less harm to human health, but for high-order wafer processes, it will affect the yield of clean room products, especially the yield of processes below 7 nanometers, such as 3 nanometer or 2 nanometer wafer processes.

[0054] The cooling area 102 of the zeolite wheel 10 is provided with two embodiments, one of which is that the cooling gas inlet pipeline 14 connected to one side of the cooling area 102 of the zeolite wheel 10 is used for fresh air to enter (as shown in Figure 2 The cooling area 102 of the zeolite wheel 10 is provided with two embodiments, one of which is that the cooling gas inlet pipeline 14 connected to one side of the cooling area 102 of the zeolite wheel 10 is used for fresh air to enter (as shown in Figure 1 The cooling area 102 of the zeolite wheel 10 is provided with two embodiments, one of which is that the cooling gas inlet pipeline 14 connected to one side of the cooling area 102 of the zeolite wheel 10 is used for fresh air to enter (as shown in Figure 1 The cooling area 102 of the zeolite wheel 10 is provided with two embodiments, one of which is that the cooling gas inlet pipeline 14 connected to one side of the cooling area 102 of the zeolite wheel 10 is used for fresh air to enter (as shown in

[0056] In addition, the outside air conditioning box (MAU) 3 is provided with an inlet 401 and an outlet 402 (as shown in Figure 1 and Figure 2 In addition, the outside air conditioning box (MAU) 3 is provided with an inlet 401 and an outlet 402 (as shown in

[0057] The outdoor air conditioning unit (MAU) 3 is provided with a box 40, which is provided with a first filter device 41, a first temperature device 42, a water washing device 43, a second temperature device 44 and a second filter device 45 (as shown in Figure 1 and Figure 2 The outdoor air conditioning unit (MAU) 3 is provided with a box 40, which is provided with a first filter device 41, a first temperature device 42, a water washing device 43, a second temperature device 44 and a second filter device 45 (as shown in

[0058] The first temperature device 42 is any one or combination of a pre-cooling coil 421 and a pre-heating coil 422 (as shown in Figure 2 The pre-cooling coil 421 is provided with any one of cooling water and chilled water, so as to effectively reduce the temperature of the gas transported by the zeolite rotary adsorption device 2. The pre-heating coil 422 is provided with any one of hot water and steam, so as to transfer heat to the gas transported by the zeolite rotary adsorption device 2, thereby increasing the temperature of the gas. In addition, the first temperature device 42 can also be any one or combination of a pre-cooler 423 and a pre-heater 424 (as shown in Figure 1 The pre-cooler 423 is any one of a shell-and-tube cooler, a finned tube cooler or a plate heat exchanger cooler, and the pre-heater 424 is any one of an electric heater, a gas heater, a heat medium oil heater or a hot water heater.

[0059] In addition, the water washing device 43 is a washing humidifier, mainly composed of at least one pressurizing pump, at least one nozzle, at least one water supplement valve, at least one water discharge valve, and at least one pipeline (not shown in the figure). When the adsorbed gas transported through the clean gas conveying pipeline 13 of the zeolite wheel adsorption device 2 passes through the washing humidifier, water molecules will fully absorb the heat in the adsorbed gas and vaporize and evaporate, increasing the humidity of the adsorbed gas transported through the clean gas conveying pipeline 13 of the zeolite wheel adsorption device 2, to form humidified gas.

[0060] In addition, the second temperature device 44 is any one or a combination of the re-cooling coil 441 and the re-heating coil 442 (as shown in Figure 2 The re-cooling coil 441 is supplied with any one of cooling water or ice water to effectively lower the temperature of the adsorbed gas transported through the clean gas conveying pipeline 13 of the zeolite wheel adsorption device 2. The re-heating coil 442 is supplied with any one of hot water or steam to transfer heat energy to the adsorbed gas transported through the clean gas conveying pipeline 13 of the zeolite wheel adsorption device 2, to increase the temperature of the adsorbed gas. In addition, the second temperature device 44 can also be any one or a combination of the re-cooler 443 and the re-heater 444 (as shown in Figure 1 The re-cooler 443 is any one of a shell-and-tube cooler, a finned tube cooler, or a plate heat exchanger cooler, and the re-heater 444 is any one of an electric heater, a gas heater, a heat medium oil heater, or a hot water heater.

[0061] The second filter device 45 is any one or a combination of a high efficiency particulate air filter (HEPA) and an ultra low penetration air filter (ULPA). The high efficiency particulate air filter (HEPA) is suitable for end filtration, with an efficiency of 99.998% for 0.1 microns and 0.3 microns, and a removal efficiency of more than 99.7% for particles with a diameter of 0.3 microns (1 / 200 of the diameter of hair) or more, which is the most effective filter medium for smoke, dust, and bacteria, and the material is mainly superfine glass fiber paper or composite filter paper. The ultra low penetration air filter (ULPA) is mainly used to remove particles of 0.12 microns (120 nanometers) or more, with a filtration effect of more than 99.995% for DOP, and the material is mainly special superfine glass fiber paper.

[0062] Furthermore, the concentration of gaseous volatile organic pollutants in the outside air is very low, generally less than 1000 ppb, and the actual concentration of IPA in the outside air is about tens of ppb. Compared with the volatile organic exhaust treatment system used in air pollution prevention and control, the concentration of volatile organic gaseous exhaust in a semiconductor electronic factory is mostly between 100-800 ppm. The applicant analyzes that there is a big difference between the two, and the concentration difference is at least 100-1000 times. Therefore, the zeolite wheel adsorption equipment 2 (as shown in Figure 1 and Figure 2 shown) is installed at the upstream end of the outside air conditioning box (MAU) 3, which can directly filter out the micro-pollutants of the outside air (Outside Air) 1, and the zeolite wheel 10 is used for adsorption and desorption. The zeolite wheel 10 can be recycled, has no consumables, has a long service life, low maintenance cost, and saves time and consumables.

[0063] In addition, the zeolite runner adsorption equipment 2 has two kinds of embodiments, wherein the first kind of embodiment is that the zeolite runner 10 is provided with a zeolite runner controller (not shown in the figure), the zeolite runner controller is set to any one of continuous operation or timing operation, mainly the zeolite runner 10 can be continuously operated for 24 hours in a way of adsorption and desorption, or can be used in a timing operation mode for adsorption and desorption, and the zeolite runner controller can be connected with the heater 11, when the zeolite runner controller is set to continuous operation or timing operation, the heater 11 can be started at the same time to heat and output heat source to the desorption zone 103, and the zeolite runner 10 in the timing operation state is stopped for a period of time according to the setting of the time, and then continues to operate to perform the adsorption and desorption action. The zeolite runner controller can also close the heater 11, so that the cooling gas transported by the cooling gas conveying pipeline 15 can directly pass through the heater 11 without heating, and then is transported into the desorption zone 103. In addition, the second kind of embodiment of the zeolite runner adsorption equipment 2 is that the zeolite runner 10 is provided with a zeolite runner desorption zone controller (not shown in the figure), the zeolite runner desorption zone controller is set to any one of continuous desorption or timing desorption, mainly the desorption zone 103 of the zeolite runner 10 can be continuously desorbed for 24 hours in a way of desorption, or can be used in a timing desorption mode for desorption, and the zeolite runner desorption zone controller can be connected with the heater 11, when the zeolite runner desorption zone controller is set to continuous desorption or timing desorption, the heater 11 can be started at the same time to heat and output heat source to the desorption zone 103. The zeolite runner desorption zone controller can also close the heater 11, so that the cooling gas transported by the cooling gas conveying pipeline 15 can directly pass through the heater 11 without heating, and then is transported into the desorption zone 103, so that the desorption zone 103 of the zeolite runner 10 in the timing desorption state is stopped for a period of time according to the setting of the time, and then continues to heat to facilitate output of heat source to the desorption zone 103 for desorption.

[0064] Especially by experiment, it is found that by making a module (for example 400mm) of zeolite blocks with the same thickness as the zeolite wheel, carrying out desorption for one hour, and then carrying out saturated adsorption capacity test experiment, it is found that it can adsorb 3.5 hours under the condition that the adsorption efficiency decreases from 100% to 80%. When the test inlet condition is IPA 11.69ppm, the experimental results show that the inlet IPA 11.69ppm can be adsorbed for 210 minutes = 3.5 hours after desorption, but the actual operation of the external gas IPA is 20~60ppb, and the total volatile organic compounds (TVOC) is <1000ppb. The external gas IPA is less adsorbed than other general pollutants, such as toluene. Therefore, based on the above, it can be inferred that the adsorption time is equivalent, and we simply calculate the expected adsorption time a after regeneration = (11.69ppm*1000ppb / ppm)*3.5 hours / 1000ppb = 40.9 hours. Therefore, when using a heated gas stream to heat desorption (hereinafter referred to as heated desorption), we have designed an intermittent heated desorption. For example: desorption for one hour. Then use for 12 hours. In this way, 24 hours of continuous desorption is not required every day. Only one hour of desorption every 12 hours is required. Such operation can greatly reduce the energy of desorption.

[0065] The details are as follows. Based on the above design, the zeolite blocks are made into a honeycomb-shaped zeolite wheel, and the speed of the honeycomb-shaped zeolite wheel is 1 RPH, that is, it takes one hour for the honeycomb-shaped zeolite wheel to rotate one circle, and the entire honeycomb-shaped zeolite wheel uses a heated gas stream to heat desorption. The heated gas stream is used to heat desorption (hereinafter referred to as heated desorption) for one hour, and then it can be used for 40.9 hours, for example, we set the safety factor SF = 3.4, 40.9 / 3.4 = 12 hours, then design intermittent heated desorption. The honeycomb-shaped zeolite wheel can be used for 12 hours after intermittent heated desorption for one hour, and one day is 24 hours, that is, it is not necessary to continuously heat desorption for 24 hours. The unique intermittent heated desorption design of the present application has the advantage of saving the electricity cost of heating.

[0066] For example, a diameter 4250mm honeycomb zeolite wheel desorption needs 8000NCMH air volume, the cooling zone outlet temperature is 150℃, needs to be heated to 220℃, the electricity price is based on NTD 3.5 yuan / kW-hr, the continuous 24 hours heating desorption power consumption is calculated as 209kW*24hr=5,020kW-hr, and then the annual operation electricity fee is calculated as 5020*360*3.5=6,325,200 yuan / year. And the intermittent heating desorption honeycomb zeolite wheel is designed by the unique design of the utility model, and the intermittent heating desorption can be used for 12 hours after one hour, and one day is 24 hours, that is, it is not necessary to continuously heat and desorb for 24 hours, and the same is a diameter 4250mm honeycomb zeolite wheel desorption needs 8000NCMH air volume, the cooling zone outlet temperature is 150℃, needs to be heated to 220℃, the electricity price is based on NTD 3.5 yuan / kW-hr, the heating desorption power consumption within 24 hours is calculated as 209kW*(1 / 12)*24hr=418kW-hr, and then the annual operation electricity fee is calculated as 418*360*3.5=526,680 yuan / year, and the power consumption difference is very large, wherein the annual operation electricity fee difference is NTD 5,798,520, and obviously, the utility model has economic benefits in the annual operation cost difference.

[0067] Therefore, the utility model mainly is through a outside air (Outside Air) 1, a zeolite wheel adsorption equipment 2, a outside air conditioning box (MAU) 3 and a clean room 4 combination design (such as Figure 1 And Figure 2 As shown), and the zeolite wheel adsorption equipment 2 is provided with a zeolite wheel 10, so that the outside air (Outside Air) 1 can first pass through the zeolite wheel 10 of the zeolite wheel adsorption equipment 2 to filter out the micro-pollutants of the outside air (Outside Air), and then is sent into the outside air conditioning box (MAU) 3, and is sent to the clean room 4 through the outside air conditioning box (MAU) 3, so that the micro-pollutants entering the clean room 4 can be greatly reduced, the filtering burden of the chemical filter screen in the clean room 4 can be reduced, the service life of the chemical filter screen in the clean room 4 can be increased, and the overall practicability is increased.

[0068] Through the above detailed description, the person skilled in the art can understand that the utility model can achieve the above-mentioned purposes, and the utility model has met the requirements of the patent law, and therefore the patent application is proposed.

[0069] The above is only a preferred embodiment of the utility model, and cannot limit the scope of the utility model embodiment, therefore, all simple equivalent changes and modifications made according to the utility model claims and the utility model specification content should still belong to the scope covered by the utility model.
