Description

Technical Field

[0001] This utility model relates to the field of semiconductor processing equipment, and in particular to an air intake component for EFEM equipment. Background Technology

[0002] In chip manufacturing, EFEM (Equipment Front End Module) equipment is required, especially plasma etching machines, which are commonly used in chip manufacturing. In the chip manufacturing process, plasma etching machines are mainly used for precise etching of semiconductor materials. Through the physical and chemical reactions between plasma and the material surface, unwanted parts are removed, thereby enabling the transfer of complex circuit patterns and the shaping of microstructures on the chip. Typically, EFEM equipment participates in chip manufacturing, and the working environment is a cleanroom. Currently, the temperature and dust levels inside the EFEM equipment's working chamber can only reach the same range and composition as the overall cleanroom environment. This is due to the characteristics and limitations of its existing environmental control mechanisms.

[0003] Although the cleanroom as a whole has created a relatively clean and stable temperature and humidity environment, the working chamber of the EFEM equipment does not have more refined environmental control measures that are independent of the larger environment. However, the working chamber of the EFEM equipment may still generate additional micro-dust particles during material transfer and equipment operation. Furthermore, it is impossible to filter and remove these internally generated micro-dust particles more efficiently. It can only maintain a micro-dust composition state similar to that of the cleanroom environment, making it difficult to further reduce the concentration of micro-dust or remove specific types of micro-impurities.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-4 An embodiment of this utility model provides an EFEM equipment air intake assembly, comprising: an equipment body 1, at least one set of air intake assemblies being provided at the air inlet of the equipment body 1; the air intake assembly comprising: a housing 2; the housing 2 being disposed outside the air inlet 3; a filter 4 being disposed on one side of the housing 2; the housing 2, the filter 4 and the air inlet 3 forming a volumetric cavity; a fan 5 and a temperature regulating component 6 being disposed inside the volumetric cavity.

[0033] In this embodiment, a temperature regulating component 6 and a filter 4 are added to the air inlet of the device body 1 to achieve further temperature control. While filtering micro-dust, the air pressure in the working chamber of the device body 1 will be reduced. A fan 5 is added to one side of the air inlet 3 to meet the working requirements. The air inlet assembly is set on the outside of the device body 1 for easy installation or disassembly.

[0034] The housing 2 includes a connecting part 21 and a mounting part 22. The connecting part 21 is a rectangular frame, and handles 23 are provided on both end faces of the connecting part 21.

[0035] In this embodiment, the device is installed with the device body 1 via the connecting part 21, and the handle 23 facilitates installation and disassembly.

[0036] The mounting part 22 is located on the side away from the device body 1, and the mounting part 22 is provided with limit grooves 24 on both sides, and the filter 4 is located inside the limit grooves 24.

[0037] In this embodiment, the filter 4 is assembled with the mounting part 22. Limiting grooves 24 are provided on both sides of the mounting part 22. The two ends of the filter 4 are placed inside the limiting grooves 24. After filtering the air, it is delivered to the equipment body 1 to further filter the air in the clean room, reduce the amount of dust entering the inside of the equipment body 1, and improve the stability of the quality of the produced products.

[0038] The size of the mounting part 22 is larger than the size of the connecting part 21, and the size of the filter 4 is larger than the size of the connecting part 21.

[0039] In this embodiment, the size of the filter 4 is larger than the size of the connection part 21, so that the air can be filtered sufficiently.

[0040] The air inlet 3 extends into the inner side of the equipment body 1, forming a recess, and the temperature regulating element 6 is set in the recess; the temperature regulating element 6 is a thermocouple or a heating resistor.

[0041] In this embodiment, the air inlet 3 is a rectangular grid-shaped partition that is recessed inward. The temperature regulating component 6 is set in the recess, which optimizes the space occupied by the air inlet assembly and does not affect the maintenance and repair of the equipment body 1.

[0042] During temperature control, the device is closer to the inside of the main body 1, which allows for more accurate temperature monitoring. Temperature control can be achieved through the device's own control system.

[0043] The fan 5 is located inside the housing 2 and installed at the end face of the equipment body 1; the fan 5 is located below the air inlet 3; two fans 5 are provided inside the housing 2, and the number of fans 5 is the same as the number of temperature regulating components 6; two sets of air inlet components are provided.

[0044] In this embodiment, by setting up a fan 5 to draw in air, and because a filter 4 is set up, the equipment body 1 will be in a negative pressure environment when filtering the air, which will not meet the working requirements of the equipment body 1. Therefore, four centrifugal fans are added to regulate the air pressure.

[0045] In this embodiment, the control system of the device body 1 controls the fan 5 and the temperature regulating component 6 to work, and adjusts the wind speed and temperature so that the working chamber of the device body 1 reaches a more suitable temperature, temperature difference and wind pressure.

[0046] All standard parts used in this embodiment can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
