Description
Technical Field
[0001] The invention relates to semiconductor temperature control cleaning equipment, belonging to the technical field of semiconductor processing. Background Art
[0002] Semiconductors are materials with electrical conductivity between insulators and conductors. Their electrical conductivity is easily controlled and can be used as a component material for information processing. From the perspective of science and technology or economic development, semiconductors are very important. The core units of many electronic products, such as computers, mobile phones, and digital recorders, use the changes in the conductivity of semiconductors to process information.
[0003] Silicon carbide has become an important semiconductor material due to its superior properties. It is a high-performance material component that is widely used in semiconductor manufacturing, optics, aerospace and other fields. It is formed into a solid material by condensing gaseous reactants on a substrate. In the process of preparing silicon carbide, the vapor of a gaseous precursor (such as trichloromethylsilane MTS, polymethylsilane PMS, etc.) is usually introduced into a reaction chamber where a substrate such as graphite is placed. A chemical reaction occurs under gaseous conditions to generate SiC, which is then deposited on the surface of the substrate to form the desired SiC.
[0004] After semiconductor materials are made, since many particles and organic matter will adhere to their surfaces, dry ice cleaning is currently commonly used for treatment. However, in actual operation, continuous flushing with dry ice will lead to low-temperature condensation, causing frost to cover impurities and reduce the efficiency of subsequent flushing. Continuous cleaning will not be able to clean completely, and it is necessary to heat up the material to melt the frost before cleaning. This will cause large temperature changes during the cleaning process, affecting the cleaning effect and making it difficult to perform efficient cleaning under constant temperature conditions. In addition, it is inconvenient to place the semiconductor materials during cleaning, affecting the operating efficiency. The heating operation during continuous cleaning will also affect the cleaning efficiency, reduce the processing quality of the semiconductor materials, and affect the subsequent processing of the semiconductor materials.

[0029] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.
[0030] like Figure 1-10 As shown, the semiconductor temperature control cleaning equipment includes: The cleaning assembly 100 includes a cleaning box 101, wherein a placement slot 102 for placing semiconductor materials is provided inside the cleaning box 101, a partition 104 is fixedly connected to the inner wall of the cleaning box 101 at the bottom of the placement slot 102, a rotating mechanism is provided in the middle of the partition 104, and the semiconductor materials are placed on the rotating mechanism through a bracket assembly 300; A lifting component 200 is fixedly installed inside the cleaning component 100, and a blowing component 400 is rotatably connected to the inner wall of the cleaning box 101 located on one side of the lifting component 200, and a guide component 500 is fixedly installed inside the cleaning box 101, and the guide component 500 is connected to the flushing component 600, and the flushing component 600 is fixedly installed inside the cleaning box 101.
[0031] As a preferred solution, the semiconductor material is placed on the bracket assembly 300 and above the cleaning assembly 100. The lifting assembly 200 can be used to stably place the semiconductor material inside the cleaning box 101, and the semiconductor material can be evenly rotated through a rotating mechanism. Dry ice flushing and gas blowing are performed alternately inside the cleaning box 101. The blowing assembly 400 is used to drive the heat insulation cover 405 to close the bracket assembly 300, which can reduce the temperature change range in the cleaning box 101 and facilitate temperature control during subsequent dry ice cleaning. The cleaned gas can carry impurities for collection and discharge, thereby realizing rapid cleaning operations of the semiconductor material.
[0032] A top plate 103 located inside the placement groove 102 is fixedly installed on the top of the cleaning box 101. The top plate 103 is a square hollow structure. Exhaust ports 105 are provided on both sides of the partition 104 located inside the cleaning box 101, and guide blocks 111 are fixedly connected to the middle of both ends of the partition 104. The guide block 111 has an inclined surface on one side close to the inner wall of the placement groove 102. The inner wall of the cleaning box 101 is respectively fixedly connected with a temperature sensor 109 and a sealing gasket 110.
[0033] By adopting such a scheme, the top plate 103 can cooperate with the lifting assembly 200 to achieve the closure of the top of the cleaning box 101. When placing semiconductor materials, the bracket assembly 300 can be moved to the top of the top plate 103 through the lifting assembly 200. At this time, the semiconductor materials can be conveniently placed, and the lifting assembly 200 can be quickly separated through the guide block 111 on the partition 104, so that it can correspond to the rotating mechanism after placement, and will not affect the normal operation of the subsequent rotating mechanism. The internal temperature of the cleaning box 101 is monitored by the temperature sensor 109.
[0034] The rotating mechanism includes a rotating motor 106, which is fixedly mounted to the bottom of the partition 104. The output end of the rotating motor 106 is fixedly connected to a turntable 107, which is rotatably connected to the top of the partition 104, and a plurality of evenly distributed positioning pins 108 are fixedly connected to the edge of the turntable 107. A bracket assembly 300 is provided on the surface of the turntable 107 for placing the semiconductor material of the annular structure. The bracket assembly 300 is composed of a carrier frame 301 and a bracket 303. The carrier The carrier frame 301 is fitted and connected to the surface of the turntable 107, and positioning holes 305 corresponding to the positioning pins 108 are opened on the edge of the carrier frame 301, symmetrically distributed ears 302 are fixedly connected on both sides of the carrier frame 301, and a ring-shaped bracket 303 is fixedly installed in the middle of the carrier frame 301 between the ears 302, and the semiconductor material is fitted and connected to the top surface of the bracket 303, and a number of evenly distributed limit blocks 304 are fixedly connected to the edge of the bracket 303, and the limit blocks 304 are in contact with the edge of the semiconductor material.
[0035] As a specific solution, when the lifting component 200 drives the bracket component 300 to move downward, the carrier frame 301 moves downward and the positioning hole 305 and the positioning pin 108 cooperate to ensure that the carrier frame 301 is stably placed on the surface of the turntable 107. At this time, the semiconductor material is supported by the bracket 303, and the semiconductor material is limited by the limit block 304. After the bracket assembly 300 is placed using the lifting component 200, when the rotating motor 106 is started to drive the turntable 107 to rotate, the turntable 107 drives the semiconductor material on the bracket assembly 300 to rotate slowly, and is fully cleaned during the flushing by the flushing component 600.
[0036] The lifting assembly 200 includes an electric push rod 201, which is embedded and installed inside the cleaning box 101. The telescopic end of the electric push rod 201 passes through the partition 104 and is fixedly connected to the frame 202. The cross-section of the frame 202 is a square hollow structure. The frame 202 is located outside the carrier frame 301. The middle of both sides of the frame 202 is fixedly connected to the top cover 205 through the vertical plate 203. The corners of the frame 202 and the vertical plate 203 are fixedly connected to the two ends of the vertical rod 204 respectively. The vertical plate 203 and the vertical rod 204 are both located inside the top plate 103, the bottom edge of the top cover 205 is fixedly connected to the sealing ring 206, and the sealing ring 206 is fitted and connected to the surface of the top plate 103, and a movable rod 207 is horizontally slidable at the bottom of the vertical plate 203. The cross-section of the movable rod 207 is a square hollow structure and is embedded and connected with the notches on both sides of the bottom of the vertical plate 203. One end of the movable rod 207 is connected to the vertical plate 203 through a spring 208, and the other end of the movable rod 207 is correspondingly arranged above the guide block 111.
[0037] As a specific solution, when placing semiconductor materials, the electric push rod 201 is started to drive the frame 202 to rise, and the frame 202 drives the vertical plate 203 and the vertical rod 204 to rise. When the frame 202 moves to the bottom of the top plate 103, the bracket assembly 300 passes through the top plate 103 and moves to the outside of the cleaning box 101. After placing the semiconductor materials, the electric push rod 201 and the electric frame 202 are reset, and the sealing ring 206 on the top cover 205 is pressed against the edge of the top plate 103, thereby achieving the sealing of the inside of the cleaning box 101; when the electric push rod 201 is extended, the movable rod 207 moves on the inclined surface of the guide block 111, through The elasticity of the spring 208 pushes the movable rod 207 to move to the side close to the bracket assembly 300. The movable rod 207 realizes its stable translation through the limit at the bottom of the vertical plate 203, so that when one end of the movable rod 207 moves to below the hanging ear 302, the carrier frame 301 is lifted to the top plate 103. When the electric push rod 201 moves downward and the carrier frame 301 is placed on the turntable 107, the movable rod 207 moves to the guide block 111. When it continues to move downward, the movement is limited by the inclined surface of the guide block 111 to move to both sides, and then separates from the bracket assembly 300, which does not affect the rotation of the turntable 107 and the carrier frame 301, and can be quickly taken and placed.
[0038] The blowing component 400 includes a driving motor 401, which is embedded and installed in the cleaning box 101. The output end of the driving motor 401 is fixedly connected to a driving shaft 402, and the end of the driving shaft 402 is fixedly connected to a round rod 403. A sleeve rod 404 is rotatably sleeved on the surface of the round rod 403. The two ends of the sleeve rod 404 are respectively fixedly connected to a gear 406 and a heat insulation cover 405. The driving shaft 402 is rotatably connected to the inside of a side plate 407, and the side plate 407 is fixedly installed to the inner wall of the cleaning box 101. A rack 408 with an arc structure is fixedly connected to the side wall of the side plate 407. The center of the arc where the rack 408 is located coincides with the axis of the driving shaft 402, and the rack 408 is correspondingly distributed with the gear 406. A sealing gasket 110 is provided above the side plate 407, and when the heat insulation cover 405 rotates, the edge of the heat insulation cover 405 fits with the surface of the sealing gasket 110.
[0039] As a preferred solution, when the driving motor 401 is working, it drives the driving shaft 402 to rotate on the side plate 407, so that the driving shaft 402 drives the round rod 403 and the sleeve rod 404 to rotate synchronously, and then drives the heat insulation cover 405 to rotate to the side of the placement groove 102, which can not affect the normal lifting of the lifting component 200. At this time, the heat insulation cover 405 and the air inlet pipe 412 and the air outlet pipe 411 are all attached to the surface of the sealing gasket 110, and the blow-off component 400 will not be affected when dry ice cleaning is performed. Afterwards, when the driving shaft 402 drives the round rod 403 and the sleeve rod 404 to rotate, the gear 406 on the sleeve rod 404 contacts the rack 408 on the side plate 407. At this time, the gear 406 drives the sleeve rod 404 to rotate on the surface of the round rod 403. The sleeve rod 404 drives the heat shield 405 to rotate and then fits on the surface of the carrier frame 301, covering the semiconductor material and the bracket 303 inside the heat shield 405, and then heating gas is transported to the inside of the heat shield 405 to melt the dry ice and blow away impurities.
[0040] The heat insulation cover 405 is a circular hollow structure, and a heater 409 is fixedly installed on the top of the heat insulation cover 405. The heater 409 is fixedly connected to the inside of the heat insulation cover 405 through a delivery pipe 410, and one end of the delivery pipe 410 located inside the heat insulation cover 405 is attached to the inner wall of the heat insulation cover 405. The heater 409 is fixedly connected to an air inlet pipe 412, and the bottom of the heat insulation cover 405 is fixedly connected to an air outlet pipe 411. The air inlet pipe 412 and the air outlet pipe 411 are both L-shaped structures and are distributed in parallel. The heat insulation cover 405 is attached to the top surface of the carrier frame 301.
[0041] Further, before the heat shield 405 is attached to the carrier frame 301, the gear 406 is separated from the rack 408. At this time, the heat shield 405 smoothly covers the edge of the carrier frame 301. At this time, the rotating motor 106 stops working. When the heat shield 405 rotates, it drives the air inlet pipe 412 and the air outlet pipe 411 to correspond to the first fixed pipe 506 and the second fixed pipe 507. The sealing of the connection is achieved by squeezing the fitting block 508. At this time, the air pump 505 is started to extract the air inside it, so that the outside air is transported to the air inlet pipe 412 through the second fixed pipe 507, and the air is heated by the heater 409 and then transported to the heat shield 405 through the delivery pipe 410. Internally, the delivery pipe 410 is arranged on the inner wall of the heat insulation cover 405, so that a vortex state of heating gas is formed inside the heat insulation cover 405, and is discharged through the outlet pipe 411 and the first fixed pipe 506, so as to realize the circulation of hot air, melt the frost attached to the surface of the semiconductor material, and blow away the impurities. When the temperature rises, the rotating motor 106 drives the heat insulation cover 405 to fit the surface of the sealing gasket 110, and continues to perform the cleaning operation by dry ice cleaning, so as to realize the alternation of dry ice cleaning and hot air blowing and suction. At the same time, the heat insulation cover 405 can isolate the heat, avoid affecting the temperature in the placement groove 102, and reduce the temperature change amplitude to facilitate the subsequent temperature control cleaning.
[0042] The guide assembly 500 includes a ring 501, which is fixedly installed on the bottom of the cleaning box 101. The ring 501 is fixedly connected to the bottom of the partition 104. A channel for gas collection is formed between the ring 501 and the cleaning tank, and the channel is located below the exhaust port 105. A cavity 502 connected to the outside is opened at the bottom of the cleaning box 101, and the cavity 502 is connected to the channel. The outer wall of the cleaning box 101 on one side of the cavity 502 is hinged with a box cover 112, and the inner wall of the cleaning box 101 located inside the cavity 502 is fixedly connected with a filter.
[0043] With such a solution, the enclosure 501 is used to isolate the passage and other electrical equipment, so that the carbon dioxide gas during dry ice cleaning enters the passage from the exhaust ports 105 on both sides of the partition 104 and is discharged after passing through the cavity 502. A filter is provided inside the cavity 502 to filter impurities during cleaning, and a box cover 112 is provided to facilitate subsequent opening for cleaning.
[0044] A dry ice particle storage tank 503 is fixedly installed on the outer wall of the cleaning box 101. The top of the dry ice particle storage tank 503 is fixedly connected to a connecting pipe 504 via a delivery pump. The connecting pipe 504 runs through the cleaning box 101 and is connected to the flushing assembly 600. A pump body 606 is fixedly installed on the outer wall of the cleaning box 101 above the connecting pipe 504. The pump body 606 is fixedly connected to the flushing assembly 600 via a branch pipe 607, and a control valve 608 is fixedly connected to the end of the branch pipe 607.
[0045] Specifically, during cleaning, the delivery pump is started to deliver dry ice particles to the inside of the nozzle 601 through the connecting pipe 504. When the dry ice particles are sprayed out from the nozzle 605, they are mixed with the high-pressure gas to discharge the dry ice particles and the gas mixture, thereby quickly removing particulate matter and organic matter on the surface of the semiconductor material.
[0046] An air pump 505 is fixedly installed inside the cleaning box 101, and the air pump 505 is located inside the circle 501 below the partition 104. An electric push rod 201 and a rotating motor 106 are also arranged inside the circle 501. The partition 104 is respectively connected with a first fixed pipe 506 and a second fixed pipe 507, and the first fixed pipe 506 and the second fixed pipe 507 are respectively distributed corresponding to the outlet pipe 411 and the inlet pipe 412. The ends of the air pipe 412 and the air outlet pipe 411 are fixedly connected to the bonding block 508, and the first fixed pipe 506 and the second fixed pipe 507 are extended to the outside of the cleaning box 101. The air pump 505 can allow the outside air to enter the heat insulation cover 405 from the second fixed pipe 507, the air inlet pipe 412 and the delivery pipe 410. The heat insulation cover 405 is used for temperature isolation to avoid affecting the low temperature environment in the placement tank 102, and to allow the hot air to heat the semiconductor material and then be discharged from the air outlet pipe 411 and the first fixed pipe 506.
[0047] The flushing assembly 600 includes a nozzle 601, which is fixedly installed to the inner wall of the cleaning box 101. An impeller 602 is rotatably connected inside the nozzle 601. The impeller 602 is rotatably connected to a bearing 603 installed inside the nozzle 601, and the end of the impeller 602 is fixedly connected to a stirring rod 604. The end of the nozzle 601 is fixedly connected to a nozzle 605, and the nozzle 605 is correspondingly arranged above the bracket assembly 300.
[0048] Furthermore, when the dry ice particles and high-pressure gas entering the nozzle 601 are ejected from the nozzle 605, the gas drives the impeller 602 to rotate, so that the impeller 602 drives the stirring rod 604 to rotate synchronously, thereby further crushing the dry ice particles to make them finer before ejecting them. During the cleaning process, the pump body 606 works to transport the gas from the branch pipe 607 to the inside of the nozzle 601, thereby adjusting the gas discharge rate in the nozzle 601 and changing the dry ice discharge amount within the corresponding time to perform temperature control. The temperature can be controlled according to the cleaning situation to achieve a constant temperature cleaning function.
