[0049] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0050] As described in the background section, current cleaning methods for semiconductor devices primarily involve overall cleaning, such as immersing the entire semiconductor device in a cleaning solvent. However, in certain specific scenarios, such as during production or research, it is necessary to clean specific areas of the semiconductor device.
[0051] As a specific example, consider a PCB board comprising components A, B, and C. During the research process, it's necessary to clean module B using a special solvent, such as an acidic solvent. However, this acidic solvent would cause surface corrosion of module A, affecting its performance. Therefore, a partial cleaning of the entire PCB board is required; that is, cleaning only module B with the acidic solvent, while excluding modules A and C.
[0052] In the existing technology, there is no device for local cleaning of semiconductor devices, which makes it impossible to achieve effective local cleaning of semiconductor devices under the above-mentioned operating conditions.
[0053] In view of this, in order to solve the above problems, this application provides a semiconductor device cleaning apparatus to achieve local cleaning of semiconductor devices.
[0054] The semiconductor device cleaning apparatus 100 provided in this application is described below by way of example:
[0055] As one implementation method, please refer to Figure 1 The semiconductor device cleaning apparatus 100 includes a lifting mechanism 110, a sample placement mechanism 120, a cleaning mechanism 130, and a drying mechanism 140. The sample placement mechanism 120 is connected to the lifting mechanism 110, and a first cleaning hole 123 is provided at the bottom of the sample placement mechanism 120. The cleaning mechanism 130 is located below the sample placement mechanism 120, and the drying mechanism 140 is located on the side of the sample placement mechanism 120. A cleaning solvent is arranged inside the cleaning mechanism 130. When in the cleaning state, the sample to be cleaned is placed inside the sample placement mechanism 120, and the sample placement mechanism 120 is immersed in the cleaning mechanism 130 under the action of the lifting mechanism 110. A portion of the sample to be cleaned comes into contact with the cleaning solvent through the first cleaning hole 123. After cleaning is completed, the lifting mechanism 110 is reset, and the sample to be cleaned is dried by the drying mechanism 140.
[0056] Understandably, when cleaning a semiconductor device using the semiconductor device cleaning apparatus 100 provided in this application, the sample to be cleaned (i.e., the semiconductor device to be cleaned) can be placed in the sample placement mechanism 120, and then the sample placement mechanism 120 can be lowered into the cleaning mechanism 130. Since the bottom of the sample placement mechanism 120 is provided with a first cleaning hole 123, when the sample placement mechanism 120 is lowered into the cleaning mechanism 130, only the position of the sample to be cleaned located in the first cleaning hole 123 can come into contact with the cleaning solvent, while the other positions cannot come into contact with the cleaning solvent. Therefore, when placing the sample to be cleaned, the position to be cleaned can be directly facing the first cleaning hole 123, while the other positions of the sample to be cleaned are blocked by the bottom of the sample placement mechanism 120, thereby achieving localized cleaning of the sample to be cleaned.
[0057] Of course, in one implementation, the semiconductor device cleaning apparatus 100 also includes a base mechanism 170, with the lifting mechanism 110, cleaning mechanism 130, and drying mechanism 140 all connected to the base mechanism 170. Furthermore, the base mechanism 170 can be hollow, allowing it to house relevant control or drive modules. For example, the drying mechanism 140 requires air jets, and its operation necessitates the use of motors, controllers, and other related structures; these electronic components can be housed within the base mechanism 170. Additionally, the base mechanism 170 is equipped with a control panel 171, which is connected to the control circuits of each mechanism.
[0058] The base mechanism 170 can be designed as a cuboid, which makes it easier to place different mechanisms.
[0059] Furthermore, as an implementation, the semiconductor device cleaning apparatus 100 also includes a suction nozzle mechanism 150, which is located above the sample placement mechanism 120. When in the cleaning state, the suction nozzle mechanism 150 is used to adsorb the sample to be cleaned and place the sample to be cleaned in the sample placement mechanism 120. After cleaning is completed, the suction nozzle mechanism 150 is used to adsorb the sample to be cleaned and remove it from the sample placement mechanism 120.
[0060] The suction nozzle mechanism 150 is used to more conveniently transfer the sample to be cleaned, for example, to transfer the sample to be cleaned into the sample placement mechanism 120, or to transfer the sample to be cleaned out of the sample placement mechanism 120.
[0061] As one implementation method, please refer to Figure 2The suction nozzle mechanism 150 includes a suction nozzle head 152 and a hollow connecting rod 151. One end of the connecting rod 151 is connected to a vacuum device, and the other end of the connecting rod 151 is detachably connected to the suction nozzle head 152. As shown in the figure, the connecting rod 151 can be L-shaped and connected to a vacuum pipeline. The vacuum device can be placed inside the base mechanism 170 and connected to the connecting rod 151 via a vacuum pipeline. The end of the connecting rod 151 is connected to the suction nozzle head 152, through which the sample to be cleaned can be adsorbed.
[0062] Furthermore, since the nozzle head 152 is detachably connected to the connecting rod 151, different models of nozzle heads 152 can be used according to different sample requirements. For example, for a 1cm*1cm sample to be cleaned, model a nozzle head 152 can be selected, while for a 2cm*2cm sample to be cleaned, model b nozzle head 152 can be selected, and the diameter of model b nozzle head 152 is larger than that of model a nozzle head 152.
[0063] To facilitate placing the sample to be cleaned within the sample placement mechanism 120 during the cleaning process, and to allow for removal of the sample from the sample placement mechanism 120 after cleaning, it is necessary to ensure relative movement between the suction nozzle mechanism 150 and the sample placement mechanism 120. Based on this, please refer to... Figure 3 The lifting mechanism 110 provided in this application can be a retractable cylinder, that is, the lifting mechanism 110 includes a first telescopic element 111, a second telescopic element 112 and a lifting base 113. The first telescopic element 111, the second telescopic element 112 and the lifting base 113 are connected in sequence, and the first telescopic element 111 can extend and retract relative to the second telescopic element 112, and the second telescopic element 112 can extend and retract relative to the lifting base 113; wherein, the suction nozzle mechanism 150 is installed on the first telescopic element 111, and the sample placement mechanism 120 is installed on the second telescopic element 112.
[0064] This configuration allows the suction nozzle mechanism 150 and the sample placement mechanism 120 to move relative to each other, while the sample placement mechanism 120 can move relative to the cleaning mechanism 130. Therefore, in the cleaning state, the suction nozzle mechanism 150 first adsorbs the sample to be cleaned, then moves downward relative to the sample placement mechanism 120, placing the sample at the bottom of the sample placement mechanism 120, ensuring that the area of the sample to be cleaned is directly opposite the first cleaning hole 123. It should be noted that the suction nozzle mechanism 150 simultaneously provides downward pressure to the sample to ensure that only a portion of the sample comes into contact with the cleaning solvent. Furthermore, the sample placement mechanism 120 moves downward and is immersed in the cleaning mechanism 130, allowing only a portion of the sample to come into contact with the cleaning solvent through the first cleaning hole 123, thus achieving localized cleaning.
[0065] After cleaning is completed, the sample placement mechanism 120 rises with the second telescopic element 112, and the suction nozzle mechanism 150 also rises with the first telescopic element 111, adsorbing the sample to be cleaned and removing it from the sample placement mechanism 120.
[0066] Of course, the lifting mechanism 110 can also adopt other structures, such as two independent telescopic rods, both of which can move up and down relative to the base mechanism 170. The suction nozzle mechanism 150 and the sample placement mechanism 120 are respectively mounted on one telescopic rod, which is not limited here.
[0067] As one implementation method, please refer to Figure 4 The sample placement mechanism 120 includes a connecting structure 121 and a placement cylinder 122. A first cleaning hole 123 is provided at the bottom of the placement cylinder 122. The placement cylinder 122 is connected to one end of the connecting structure 121, and the other end of the connecting structure 121 is connected to a second telescopic element 112. Furthermore, to protect the sample to be cleaned, please refer to... Figure 5 The semiconductor device cleaning apparatus 100 also includes an anti-corrosion gasket 180, which is provided with a second cleaning hole 181. The anti-corrosion gasket 180 is located at the bottom of the sample placement mechanism 120, and the projected area of the second cleaning hole 181 is located within the projected area of the first cleaning hole 123.
[0068] In this application, the area of the second cleaning hole 181 on the anti-corrosion gasket 180 is less than or equal to the area of the first cleaning hole 123. On one hand, the anti-corrosion gasket 180 serves an anti-corrosion function, ensuring that parts of the sample that do not require cleaning do not come into contact with the cleaning solvent. On the other hand, by increasing the number of anti-corrosion gaskets 180, various sizes of second cleaning holes 181 can be prepared to accommodate different areas requiring localized cleaning, providing greater flexibility.
[0069] For example, when device a has an area of 1 cm² that needs to be cleaned. 2 The area that device b needs to be cleaned is 2 cm². 2 If both use the same anti-corrosion gasket 180, then the cleaning area of device b is only 1 cm². 2 This does not meet the actual cleaning requirements. Conversely, when the area of device a that needs to be cleaned is 2cm², 2 The area of device b that needs to be cleaned is 1 cm². 2 If both use the same anti-corrosion gasket 180, then the cleaning area of device b is 2cm². 2 It will clean away any excess material.
[0070] Therefore, by setting anti-corrosion gaskets 180 with second cleaning holes 181 of different areas, different anti-corrosion gaskets 180 can be replaced according to actual needs, which meets the actual usage requirements of the box.
[0071] Please see Figure 6 The diagram shows a schematic of the anti-corrosion gasket 180 installed at the bottom of the sample placement mechanism 120. The dotted line in the diagram represents the anti-corrosion gasket 180, and the second cleaning hole 181 on the anti-corrosion gasket 180 is opposite to the first cleaning hole 123 at the bottom of the sample placement mechanism 120. Therefore, it can be ensured that after the sample to be cleaned is placed, only the part of the sample to be cleaned will come into contact with the cleaning solvent, so as to achieve the purpose of local cleaning.
[0072] As one implementation method, please refer to Figure 7 The cleaning mechanism 130 includes an annular body 131 and a placement groove 132. The annular body 131 and the placement groove 132 are connected. The cleaning solvent is arranged inside the annular body 131. When in the cleaning state, the sample placement mechanism 120 is placed in the placement groove 132 and extends into the annular body 131.
[0073] In this application, the annular body 131 is provided as a square ring. The semiconductor device cleaning apparatus 100 also includes a fixing member, which is connected to the base mechanism 170 and the annular body 131 respectively, thereby fixing the annular body 131 to the base mechanism 170.
[0074] In addition, the semiconductor device cleaning apparatus 100 also includes a heating mechanism 160, which is connected to one end of the annular body 131; see also Figure 8 When in the cleaning state, the heating mechanism 160 heats the cleaning mechanism 130 so that the cleaning solvent circulates along the annular body 131.
[0075] When the heating mechanism 160 starts heating, the cleaning solvent in the annular body 131 will generate a hydrothermal circulation effect after being locally heated, and then start to circulate in the annular body 131 to clean the sample to be cleaned. It can also wash away the reactants and dirt that have been cleaned in time, increasing the cleaning effect. The cleaning time can be set according to actual needs.
[0076] Furthermore, to achieve a more thorough cleaning, the sample placement mechanism 120 extends to half its height within the annular body 131. According to fluid dynamics formulas, this arrangement allows for a higher flow rate of the cleaning solvent below the sample placement mechanism 120 because the channel cross-sectional area is smaller than other areas. This effectively flushes specific parts of the sample, improving the cleaning effect.
[0077] As one implementation method, please refer to Figure 9The drying mechanism 140 includes a first drying element 141 and a second drying element 142, which are arranged opposite to each other. After cleaning, the air nozzles 144 of both the first drying element 141 and the second drying element 142 are facing the sample to be cleaned. Furthermore, a control panel 171 is provided on the base mechanism 170, allowing the user to control the airflow of the first drying element 141 and the second drying element 142, as well as the lifting mechanism 110, through the control panel 171.
[0078] Please refer to Figure 10 Both the first drying element 141 and the second drying element 142 include an air rod 143 and an air nozzle 144, and the air rod 143 is L-shaped and connected to the base mechanism 170.
[0079] The first drying element 141 and the second drying element 142 spray hot air relative to each other to achieve convection, which can accelerate the drying speed of the sample to be cleaned.
[0080] Therefore, the working principle of the semiconductor device cleaning apparatus 100 provided in this application is as follows:
[0081] First, such as Figure 11 As shown, the corresponding cleaning solvent is added to the cleaning mechanism 130. Then, the nozzle device of the suction nozzle mechanism 150 is opened through the control panel 171 on the base mechanism 170. The sample to be cleaned is placed under the nozzle and sucked up using tweezers or other tools. In the figure, A represents the sample to be cleaned.
[0082] Please refer to the following: Figure 12 The first telescopic element 111 retracts downwards under the control panel 171. At this time, the sample to be cleaned is sucked up by the suction nozzle mechanism 150 and gradually moves downwards until it contacts the anti-corrosion gasket 180. Next, please refer to... Figure 13 The second shrinking element is controlled to move downward. During the movement, the positional relationship between the second shrinking element and the first shrinking element remains unchanged. The positional relationship between the fixedly connected suction nozzle structure and the sample placement cylinder 122 also remains unchanged, so that the sample to be cleaned is immersed in the cleaning agent and only contacts the cleaning agent through the first cleaning hole 123 and the second cleaning hole 181.
[0083] Then, the heating function is turned on via control panel 171, causing heating mechanism 160 to heat up. The cleaning solvent in cleaning mechanism 130, after being locally heated, will generate a hydrothermal circulation effect, circulating within cleaning mechanism 130 for cleaning. This also promptly washes away the reactants and dirt, increasing the cleaning effect. Of course, the cleaning time can be set according to actual needs. After cleaning is complete, lifting mechanism 110 automatically returns to its original position.
[0084] After the sample is cleaned and reset, the drying mechanism 140 sprays hot air from the nozzle 144. This patent features drying mechanisms 140 on both sides of the base, using convection airflow to accelerate the drying of the cleaned sample area. During the reset process, the second shrinking element first moves upwards, resetting to its original position. Figure 12 The structure then moves the first telescopic element 111 upwards, resetting to its original position. Figure 11 After forming the structure, it can be dried.
[0085] Based on the above implementation, this application embodiment also provides a semiconductor device cleaning system, which includes the semiconductor device cleaning apparatus 100 described above.
[0086] In summary, this application provides a semiconductor device cleaning apparatus, which includes a lifting mechanism, a sample placement mechanism, a cleaning mechanism, and a drying mechanism. The sample placement mechanism is connected to the lifting mechanism, and a first cleaning hole is provided at the bottom of the sample placement mechanism. The cleaning mechanism is located below the sample placement mechanism, and the drying mechanism is located to the side of the sample placement mechanism. A cleaning solvent is disposed inside the cleaning mechanism. When in the cleaning state, the sample to be cleaned is placed inside the sample placement mechanism, and the sample placement mechanism is immersed in the cleaning mechanism under the action of the lifting mechanism. A portion of the sample to be cleaned comes into contact with the cleaning solvent through the first cleaning hole. After cleaning is completed, the lifting mechanism resets, and the sample to be cleaned is dried by the drying mechanism. Because this application allows for partial contact between the sample to be cleaned and the cleaning solvent through the first cleaning hole of the sample placement mechanism when cleaning semiconductor devices, it enables localized cleaning of semiconductor devices.
