Description

Technical Field

[0002] In semiconductor manufacturing technology, the particles on the wafer are a crucial factor in assessing wafer quality. These particles directly impact wafer performance, making particle control extremely important.

[0003] During wafer processing, contact between wafers and their placement sites is inevitable. If the surface of a placement site is contaminated with particles, it will interfere with the wafer placed there, affecting wafer processing. For example, during back-side processing, a protective film needs to be applied to the front side of the wafer. During the cutting of this protective film, particles are generated on its surface. When the wafer with these particles enters the thinning machine, the grinding head acts on the back side. When the wafer is thinned to a certain extent, the particles on the protective film surface can cause cracks in the wafer, rendering it unusable.

[0004] The extent to which related technologies can clean particles is limited. Utility Model Content

[0032] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0033] One embodiment of this utility model provides a semiconductor processing apparatus, in conjunction with reference to [reference]. Figure 1 and Figure 2 ,include:

[0034] Positioning structure 400;

[0035] First transmission structure 200; and

[0036] The cleaning unit 100 is located between the positioning structure 400 and the first transmission structure 200;

[0037] The cleaning unit 100 includes an ion blowing structure 110 and an air suction structure 120. The ion blowing structure 110 is used to blow ion wind onto the semiconductor structure, and the air suction structure 120 is used to adsorb particles falling from the surface of the semiconductor structure into the air suction structure 120.

[0038] In this embodiment, the first transmission structure 200 is used to transport the semiconductor structure above the cleaning unit 100 to the positioning structure 400. The ion blowing structure 110 is used to blow ion wind onto the semiconductor structure, removing particles from the surface of the semiconductor structure. The suction structure 120 is used to adsorb particles that fall from the surface of the semiconductor structure into the suction structure 120, thereby reducing the probability of particles adhering to the processing platform and improving the degree of cleaning of particles on the semiconductor structure surface.

[0039] Ion wind is an airflow that includes both positively charged and negatively charged ions.

[0040] In this embodiment, reference Figure 2 The ion blowing structure 110 includes a nozzle 112, which is inclined toward the suction structure 120. The ion blowing structure 110 provides ionized air. The nozzle 112 blows the ionized air toward the semiconductor structure. Because the nozzle 112 is inclined toward the suction structure 120, the ionized air ejected by the nozzle 112 obliquely sweeps the surface of the semiconductor structure. The ejection direction of the nozzle 112 is not perpendicular to the surface of the semiconductor structure, which makes it easier to blow particles off the surface of the semiconductor structure.

[0041] In this embodiment, reference Figure 2 The ion wind blowing structure 110 also includes a blowing chamber 111, which contains ion wind, and the nozzle 112 is connected to the blowing chamber 111.

[0042] In this embodiment, the semiconductor processing device further includes a first conduit (not shown), which is connected to the blowing chamber 111. Ionized air enters the blowing chamber 111 from the first conduit.

[0043] In other embodiments, the spray direction of the nozzle onto the surface of the semiconductor structure is not limited. The spray direction of the nozzle may be perpendicular to the surface of the semiconductor structure.

[0044] In this embodiment, reference Figure 2 The suction structure 120 includes a suction port 121. The nozzle 112 is angled toward the suction structure 120, and correspondingly, the height of the suction port 121 facing the edge of the ion blowing structure 110 is less than the height of the suction port 121 away from the edge of the ion blowing structure 110. This makes it easier for the suction port 121 to adsorb particles falling from the surface of the semiconductor structure.

[0045] In other embodiments, the height of the air intake facing the edge of the ion blowing structure is greater than or equal to the height of the air intake away from the edge of the ion blowing structure.

[0046] In this embodiment, the semiconductor processing apparatus further includes a processing cavity A, wherein the positioning structure 400, the first transmission structure 200, and the cleaning unit 100 are located in the processing cavity A.

[0047] The height of the side edge of the air intake 121 facing the ion blowing structure 110 refers to the height from the side edge of the air intake 121 facing the ion blowing structure 110 to the bottom surface of the processing chamber A. The height of the side edge of the air intake away from the ion blowing structure refers to the height from the side edge of the air intake away from the ion blowing structure to the bottom surface of the processing chamber A.

[0048] In this embodiment, reference Figure 2 The suction structure 120 further includes: a suction chamber (not shown), with a suction port 121 disposed on the top wall of the suction chamber; and one or more exhaust pipes located in the suction chamber, the exhaust pipes communicating with the suction port 121. The particles adsorbed by the suction port 121 are discharged through the exhaust pipes. Furthermore, multiple exhaust pipes are arranged in an array.

[0049] In this embodiment, an ion blowing structure 110 and an air suction structure 120 constitute a sub-unit. The cleaning unit 100 includes one or more sub-units. In this embodiment, the cleaning unit 100 includes multiple sub-units. In other embodiments, the cleaning unit includes only one sub-unit.

[0050] When the cleaning unit 100 includes multiple sub-units, during the process of the first transmission structure 200 passing the semiconductor structure over the cleaning unit 100, the first transmission structure 200 moves the semiconductor structure along the arrangement direction of the multiple sub-units, thereby enabling the multiple sub-units to clean the particles on the surface of the semiconductor structure, thus further improving the degree of cleaning of the particles on the surface of the semiconductor structure.

[0051] In this embodiment, for the ion blowing structure 110 and the suction structure 120 in the sub-unit, the ion blowing structure 110 is located on the side of the suction structure 120 away from the positioning structure 400, and the suction structure 120 is located on the side of the ion blowing structure 110 away from the first transmission structure 200.

[0052] In other embodiments, for the ion blowing structure and the suction structure in the sub-unit, the suction structure is located on the side of the ion blowing structure away from the positioning structure, and the ion blowing structure is located on the side of the suction structure away from the first transmission structure.

[0053] When the cleaning unit 100 includes multiple sub-units, the arrangement direction of the multiple sub-units is perpendicular to the arrangement direction of the ion blowing structure 110 to the suction structure 120 in the sub-units.

[0054] The total dimension of the multiple sub-units in the arrangement direction is greater than the spacing dimension corresponding to the minimum distance between the positioning structure 400 and the first transmission structure 200.

[0055] In one embodiment, the ion blowing structure 110 and the suction structure 120 in the subunit are fixedly connected. This makes the arrangement of the ion blowing structure 110 and the suction structure 120 in the subunit more compact. In other embodiments, the ion blowing structure and the suction structure are spaced apart.

[0056] In one embodiment, adjacent sub-units are detachably connected. The number of sub-units in cleaning unit 100 can be adjusted. In other embodiments, adjacent sub-units are fixedly connected.

[0057] In this embodiment, the semiconductor processing device further includes a vibration structure (not shown), which is connected to the first transmission structure 200 and is used to vibrate the first transmission structure 200.

[0058] refer to Figure 3 The first transmission structure 200 includes a first robotic arm 201, one end of which is provided with a first suction cup for adsorbing semiconductor structures.

[0059] When the first transmission structure 200 transmits the semiconductor structure to the top of the cleaning unit 100, the ion blowing structure 110 blows ion wind onto the semiconductor structure, causing particles on the surface of the semiconductor structure to detach from the surface of the semiconductor structure. The vibration structure vibrates the first transmission structure 200, causing the semiconductor structure to vibrate. In this way, particles on the side of the semiconductor structure facing the cleaning unit 100 fall off by shaking. The suction structure 120 adsorbs the particles that fall off the surface of the semiconductor structure into the suction structure 120.

[0060] In other embodiments, the semiconductor processing device may not include a vibration structure.

[0061] In this embodiment, the positioning structure 400 includes a positioning platform and an image sensor. The image sensor is used to acquire images of the semiconductor structure above the positioning platform. By processing the acquired images, the position of the center of the semiconductor structure is obtained.

[0062] In this embodiment, reference Figure 1 The semiconductor processing apparatus further includes: a processing platform 900; and a second transmission structure 710 for transmitting the semiconductor structure self-positioning structure 400 to the processing platform 900.

[0063] In this embodiment, the processing platform 900 includes a polishing platform. The semiconductor processing apparatus also includes a polishing head for polishing the semiconductor structure. In other embodiments, the processing platform 900 may also be a platform for other process treatments.

[0064] In this embodiment, there are multiple grinding heads, some of which are coarse grinding heads 910, and some are fine grinding heads 920. The grinding precision of the fine grinding head is greater than that of the coarse grinding head. The semiconductor structure is ground by the coarse grinding head 910 and then by the fine grinding head 920.

[0065] In this embodiment, the processing platform 900 can rotate around its central axis. The second transmission structure 710 is used to transmit the semiconductor structure self-positioning structure 400 to the processing platform 900. After the processing platform 900 rotates, it places the semiconductor structure below the coarse grinding head 910. After the coarse grinding head 910 finishes grinding the semiconductor structure, the processing platform 900 rotates again to place the semiconductor structure below the fine grinding head 920. After the fine grinding head 920 finishes grinding the semiconductor structure, the processing platform 900 rotates again to place the semiconductor structure at a position horizontally spaced from both the fine grinding head 920 and the coarse grinding head 910.

[0066] In other embodiments, the multiple grinding heads have the same grinding precision. In other embodiments, the number of grinding heads is one.

[0067] The second transmission structure 710 includes a second robotic arm, one end of which is provided with a second suction cup for adsorbing semiconductor structures.

[0068] Because the cleaning unit 100 cleans the semiconductor structure, the degree of compression between the particles and the semiconductor structure can be reduced when the semiconductor structure on the processing platform 900 is processed, thus reducing the degree of cracking in the semiconductor structure and reducing the probability of the semiconductor structure being scrapped.

[0069] In this embodiment, reference Figure 1 The semiconductor processing apparatus further includes: a cleaning structure 500; a third transfer structure 720, the third transfer structure 720 being used to transfer the semiconductor structure from the processing platform 900 to the cleaning structure 500; wherein, the first transfer structure is used to remove the semiconductor structure from the cleaning structure 500.

[0070] The cleaning structure 500 cleans the semiconductor structure processed by the processing platform 900. The cleaning structure 500 includes a cleaning stage and a spraying structure. After the third transfer structure 720 transfers the semiconductor structure from the processing platform 900 to the cleaning stage, the spraying structure sprays a cleaning solution onto the semiconductor structure, thereby cleaning the semiconductor structure.

[0071] refer to Figure 1 The semiconductor processing apparatus also includes a moving device, which includes a moving guide rail 610, a first moving base 620, and a second moving base 630. The first moving base 620 and the second moving base 630 are located on the side of the moving guide rail 610 away from the processing platform 900. Both the first moving base 620 and the second moving base 630 are used to move along a first direction parallel to the moving guide rail 610 and a second direction perpendicular to the moving guide rail 610. One end of the second transmission structure 710 is fixedly connected to the first moving base 620, and one end of the third transmission structure 720 is fixedly connected to the second moving base 630.

[0072] The second robotic arm 201 has a second suction cup at one end, and the other end of the second robotic arm 201 is fixedly connected to the first movable base 620. The third robotic arm has a third suction cup at one end, and the other end of the third robotic arm is fixedly connected to the second movable base.

[0073] In this embodiment, the first transmission structure 200 is located on the side of the first movable base 620 and the second movable base 630 opposite to the movable guide rail 610; the cleaning structure 500 and the positioning structure 400 are located on the side of the movable guide rail 610 opposite to the processing platform 900, and the first movable base 620 and the second movable base 630 are located between the cleaning structure 500 and the positioning structure 400. Specifically, the first movable base 620 is located between the second movable base 630 and the positioning structure 400, and the second movable base 630 is located between the first movable base 620 and the cleaning structure 500.

[0074] In this embodiment, reference Figure 1 The semiconductor processing apparatus also includes a first loading box 310 and a second loading box 320. The first loading box 310 and the second loading box 320 are disposed on the side of the processing cavity A.

[0075] The first transfer structure 200 is used to remove the semiconductor structure from the first loading cassette 310, and the semiconductor structure removed from the first loading cassette 310 is transferred above the cleaning unit 100 to the positioning structure 400. The first transfer structure 200 is also used to transfer the semiconductor structure from the cleaning structure 500 to the second loading cassette 320.

[0076] In this embodiment, reference Figure 1 The semiconductor processing apparatus also includes a fan 810, which is located on the side of the moving guide rail 610 away from the positioning structure 400 and on the side of the processing platform 900. The second transmission structure 710 passes over the fan 810 during the process of transferring the semiconductor structure from the positioning structure 400 to the processing platform 900, and the fan 810 blows the semiconductor structure.

[0077] In this embodiment, reference Figure 1 The semiconductor processing apparatus also includes a brushing structure 820, which is used to brush the surface of the processing platform 900 to remove foreign matter from the surface of the processing platform 900. After the brushing structure 820 brushes the surface of the processing platform 900, the second transfer structure 710 transfers the semiconductor structure self-positioning structure 400 to the processing platform 900, thereby reducing the pressure exerted on the semiconductor structure by foreign matter on the surface of the processing platform 900 during the processing process.

[0078] In this embodiment, the surface of the processing platform 900 has adsorption holes and liquid flow holes. The adsorption holes are used to adsorb semiconductor structures, and the liquid flow holes provide cleaning fluid. The brushing structure 820 removes foreign objects from the surface of the processing platform 900 by brushing the cleaning fluid on the surface of the processing platform 900.
