[0050] Figure 1 FIG. 1 is a plan layout diagram conceptually illustrating a semiconductor package cutting and sorting apparatus 1000 according to some embodiments of the present invention.
[0051] First, if Figure 1 As shown, the semiconductor package cutting and sorting device 1000 according to some embodiments of the present invention can be used to perform a cutting and sorting process for manufacturing semiconductor devices. Specifically, the semiconductor package cutting and sorting device 1000 can be used to cut a semiconductor strip G and divide it into a plurality of independent semiconductor packages P, and inspect and sort the semiconductor packages P.
[0052] The semiconductor package cutting and sorting device 1000 includes: a cutting module 2000 for cutting a semiconductor strip G and dividing it into a plurality of independent semiconductor packages P; an inspection module 3000 for inspecting the semiconductor packages P; and a semiconductor package conveying module 4000 for classifying and conveying the semiconductor packages P based on the inspection results of the inspection module 3000.
[0053] For example, a magazine 5000 containing a plurality of semiconductor strips G may be configured on one side of the cutting module 2000. In addition, a gripper (not shown) for extracting the semiconductor strips G from the magazine 5000 may be provided, and the semiconductor strips G extracted from the magazine 5000 may be guided by the guide rail 320.
[0054] The cutting module 2000 may include: a strip picker 2100 for picking up and transferring the semiconductor strip G; a strip picker driving unit 2120 for moving the strip picker 2100 in the vertical direction and the horizontal direction; and a vacuum plate 2200 for placing the semiconductor strip G. The strip picker 2100 may be configured to rotate by the strip picker driving unit 2120 to adjust the placement direction of the semiconductor strip G.
[0055] For example, the strip picker 2100 may pick up the semiconductor strip G extracted from the magazine 5000 , and then rotate the semiconductor strip G, and then transfer the rotated semiconductor strip G onto the vacuum plate 2200 .
[0056] The vacuum plate 2200 may be supported by a carrier plate 2220, which may move the semiconductor strip G to the cutting unit 2300. The cutting unit 2300 may include a blade for cutting the semiconductor strip G, and the carrier plate 2220 may be moved by a separate driving portion so that the semiconductor strip G is located below the cutting unit 2300.
[0057] The independent semiconductor packages P divided by the cutting unit 2300 can be picked up and transferred by the package picker 2400. The cutting module 2000 may include a cleaning unit 2500 for cleaning the independent semiconductor packages P. The package picker 2400 is configured to be movable in the vertical direction and the horizontal direction by the package picker driving unit 2420. For example, the package picker driving unit 2420 can move the package picker 2400 to the top of the cleaning unit 2500 after the semiconductor package P is picked up by the package picker 2400, and the cleaning unit 2500 can remove foreign matter from the semiconductor package P using a cleaning brush and a cleaning liquid. In addition, the cleaning unit 2500 can dry the semiconductor package P by spraying air to the semiconductor package P.
[0058] After cleaning and drying the semiconductor package P, the package picker 2400 may transfer the semiconductor package P to the semiconductor package transfer module 4000. For example, the semiconductor package transfer module 4000 may include a tray stage 4100 for supporting the semiconductor package P, and the package picker 2400 may transfer the semiconductor package P to the tray stage 4100.
[0059] The semiconductor package transfer module 4000 may include a stage transfer unit 4120 for moving the tray stage 4100 along a first horizontal direction, for example, along the Y-axis direction. The inspection module 3000 is disposed above a moving path of the tray stage 4100 and may include a first vision unit 3100 for inspecting the semiconductor package P on the tray stage 4100.
[0060] The semiconductor package transfer module 4000 may include a first tray 4200 and a second tray 4220 for accommodating semiconductor packages P. For example, the semiconductor package transfer module 4000 may include a plurality of pickers 4300 for picking up semiconductor packages P from the tray stage 4100 and transferring to the first tray 4200 or the second tray 4220. At this time, the inspection module 3000 may include a second vision unit 3200 for inspecting the semiconductor package P picked up by the picker 4300. As an example, as shown in the figure, the inspection module 3000 may include a second vision unit 3200 configured below the moving route of the picker 4300 and for inspecting the semiconductor package P picked up by the picker 4300. The first tray 4200 and the second tray 4220 may be equipped with pockets for accommodating semiconductor packages P, respectively.
[0061] The first tray 4200 and the second tray 4220 may be disposed below the moving path of the picker 4300, and the picker 4300 may be configured to move along a second horizontal direction, such as the X-axis direction, through the picker driving unit 4320. In addition, the semiconductor package conveying module 4000 may include a tray conveying unit 4240 for moving the first tray 4200 and the second tray 4220 along the first horizontal direction.
[0062] The stage transfer part 4120 and the tray transfer part 4240 may move the tray stage 4100 and the first tray 4200 and the second tray 4220 to the classification area, for example, to below the moving path of the picker 4300. In addition, the semiconductor package transfer module 4000 may include a tray supply part 4400 for supplying the first tray 4200 and the second tray 4220, and a container 4420 for recovering defective semiconductor packages P.
[0063] for Figure 2 The substrate processing apparatus 100 according to some embodiments of the present invention, which will be described below, can be applied to various unnecessary parts cut in the cutting module 2000 or separated and dropped from the cleaning unit 2500 and Figure 1 In addition to the container 4420, it can also be applied to various wastes.
[0064] Figure 2is a cross-sectional view showing a substrate processing apparatus 100 according to some embodiments of the present invention, Figure 3 It is shown Figure 2 A cross-sectional view of a substrate strip S in a cutting state of a substrate processing apparatus 100. Figure 4 It is shown Figure 3 A plan view of a substrate strip S of a substrate processing apparatus 100.
[0065] like Figures 2 to 4 As shown, a substrate processing apparatus 100 according to some embodiments of the present invention may include a waste conveying apparatus 10 , a waste crushing apparatus 20 , and a filtering apparatus 30 .
[0066] For example, Figure 2 As shown, the waste conveying device 10 may be a device for conveying the waste 1 to the exhaust port Cb formed at one side of the process chamber C using the working fluid F.
[0067] For example, Figures 2 to 4 As shown, the process chamber C may be a process chamber for a cutting process, wherein a blade B rotated by a motor M forms a cut K on a substrate strip S, thereby cutting the substrate strip S into a plurality of individual substrates U.
[0068] In addition, for example, at least a portion of the bottom surface of the process chamber C may be formed with a guide slope Ca for guiding the waste 1 .
[0069] However, these process chambers C are not necessarily limited to the drawings, and may be applicable to various situations according to the form or type of equipment that generates various forms of waste.
[0070] The working fluid F may be high pressure air or water to transmit the conveying pressure to the waste 1. However, the working fluid F is not necessarily limited thereto, and a mixed liquid of water and alcohol, an inert gas such as nitrogen or helium, various cleaning agents or working media may be used.
[0071] In addition, for example, Figure 4 As shown, the waste 1 may be an unnecessary portion remaining at an edge portion of the substrate strip S or the like after the substrate strip S is cut to form individual substrates U in the semiconductor package cutting and sorting apparatus 1000 .
[0072] In addition, for example, a gate valve 14 may be provided at the discharge port Cb to achieve selective discharge of the waste 1 and prevent the influence caused by the discharged waste 1 in advance.
[0073] For example, Figure 2As shown, the waste crushing device 20 can be a device that can crush the waste 1 generated in the semiconductor production process and discharged from the discharge port Cb into smaller-sized crushed products 2 of several centimeters or millimeters in size for easy processing, management or transportation.
[0074] The size of the crushed material 2 can be determined according to factors such as the size of the conveying pipe, so the crushed material 2 crushed into such a small size is not only easy to handle and manage, but also can prevent the pipe from being blocked during conveyance, thus facilitating conveyance.
[0075] More specifically, the waste pulverizing device 20 may be, for example, a grinder pump 21 having a pulverizing function and a conveying function so as to be able to pulverize and convey the waste 1 .
[0076] However, the waste pulverizing device 20 is not necessarily limited to the drawings, and various types of pulverizers and agitators may be applied.
[0077] The filtering device 30 may be a device that filters the pulverized matter 2 and discharges only the working fluid F by separating the pulverized matter 2 pulverized into a smaller size of several centimeters or millimeters from the working fluid F for easy handling, management, or transportation.
[0078] More specifically, the filter device 30 includes a collection body 31 and a filter 32. The collection body 31 has a receiving space formed therein; the filter 32 is received in the collection body 31 and has fine pores or a filter screen formed therein so that the crushed material 2 remains and only the working fluid F is discharged.
[0079] By using such a filtering device 30 , the pulverized material 2 and the working fluid F can be separated, and the pulverized material 2 can be filtered to discharge only the working fluid F. The filtered pulverized material 2 can be dried, incinerated, or discarded for separate management.
[0080] Therefore, according to the present invention, the waste conveying device 10 can use the working fluid F to convey the waste 1 generated in the semiconductor production process to the discharge port Cb, the waste crushing device 20 can crush the waste 1 discharged from the discharge port Cb into smaller sizes, and the filtering device 30 separates the crushed material 2 crushed into a smaller size from the working fluid F, thereby filtering the crushed material 2 and discharging only the working fluid F to the outside.
[0081] Therefore, waste 1 such as unnecessary parts, other materials or defective products generated in the semiconductor production process can be automatically crushed into smaller-sized crushed materials 2 and automatically discharged to the outside. Without relying on manual operation by operators, the inside of the equipment can always be managed cleanly, thereby producing high-quality products, greatly saving working time and manpower, and maximizing production efficiency.
[0082] Figure 5 It is shown Figure 2 1 is a side view of the waste conveying device 10 of the substrate processing device 100.
[0083] like Figure 5 As shown, the waste conveying device 10 of the substrate processing device 100 according to some embodiments of the present invention includes a nozzle device 11, a nozzle moving device 12 and a water outlet device 13. The nozzle device 11 is arranged in the process chamber C and has a plurality of injection ports 11a formed in the direction of the discharge port Cb for injecting the working fluid F in a straight line or in a vortex form. The nozzle moving device 12 moves the nozzle device 11 in the direction of the discharge port Cb along a guide member (e.g., a track) R. The water outlet device 13 can supply water to the bottom surface of the process chamber C so as to form a water film between the bottom surface of the process chamber C and the waste 1.
[0084] Therefore, when the waste conveying device 10 is used, a separate camera or sensor is used to confirm the stacking state of the waste 1, or the working fluid F is supplied to the nozzle device 11 at a predetermined time so as to spray the working fluid F in a straight line or vortex form toward the discharge port Cb. At the same time, a water film is formed between the bottom surface of the process chamber C and the waste 1 by the water discharge device 13, and then the nozzle device 11 is moved toward the discharge port Cb along the track R by the nozzle moving device 12, and the waste 1 falling on the ground can be moved toward the discharge port Cb under the pressure of the working fluid F and discharged.
[0085] Figure 6 It is shown Figure 2 A cross-sectional view of a waste crushing device 20 of a substrate processing device 100, Figure 7 It is shown Figure 6 A plan view of the cutter 212 of the grinding pump 21, Figure 8 It is shown Figure 6 A plan view of the impeller 213 of the grinding pump 21.
[0086] like Figures 6 to 8 As shown, the waste crushing device 20 can be a grinding pump 21, and a suction port 21a for sucking waste 1 and water is formed on one side of the grinding pump 21, and a discharge pipe 21b for discharging crushed material 2 and water is formed on the other side of the grinding pump 21.
[0087] For example, Figure 6 As shown, the grinding pump 21 may include a pump body 211, a cutter 212, an impeller 213, and a pump motor 214. The pump body 211 is formed with a suction port 21a and a discharge pipe 21b; the cutter 212 crushes the waste 1 sucked through the suction port 21a; the impeller 213 generates a transmission pressure to the crushed material 2 crushed by the cutter 212 and water; and the pump motor 214 is formed in the pump body 211 and rotates the cutter 212 and the impeller 213.
[0088] Therefore, when the pump motor 214 rotates the cutter 212 and the impeller 213, the cutter 212 can crush the waste 1 sucked through the suction port 21a into crushed material 2, and the impeller 213 generates a transmission pressure for the crushed material 2 and water crushed by the cutter 212 and discharges them to the discharge pipe 21b.
[0089] For example, Figure 7 As shown, the cutter 212 includes a cutter body 212a and a cutter blade 212b. A rotating shaft hole H1 connected to the rotating shaft 214a of the pump motor 214 is formed at the center of the cutter body 212a, and a through window W is formed at the outer edge of the cutter body 212a; the cutter blade 212b is formed in the through window W of the cutter body 212a, and the front end of the cutter blade 212b is formed to be sharp so that the waste 1 can be crushed.
[0090] Therefore, when the cutter 212 is used, when the pump motor 214 rotates the cutter 212 , the waste 1 flowing into the through window W can be crushed into smaller sized crushed objects 2 by the cutter blade 212 b , and the crushed objects 2 can be moved to the impeller 213 .
[0091] For example, Figure 8 As shown, a rotating shaft hole portion H2 connected to the rotating shaft 214a of the pump motor 214 may be formed at the center of the impeller 213, an input portion 213a may be formed at the upper or lower portion of the impeller 213, and a discharge portion 213b may be formed at the side of the impeller 213 so as to form a pressure difference through centrifugal force.
[0092] Therefore, when the impeller 213 is used, when the impeller 213 is rotated by the pump motor 214, the crushed material 2 and the working fluid F flowing into the input part 213a can be discharged to the discharge part 213b by centrifugal force, so that a transmission pressure can be formed, and under this transmission pressure, the crushed material 2 and the working fluid F can be transmitted to the discharge pipe 21b.
[0093] Fig. 9 It is shown Figure 2 FIG. 1 is a side view of the filter device 30 of the substrate processing apparatus 100 .
[0094] like Figure 2 and Fig. 9 As shown, the filter device 30 of the substrate processing device 100 according to some embodiments of the present invention includes a capture group 31 and a filter 32. The capture group 31 has a receiving space formed therein; the filter 32 is received in the capture group 31 and has fine pores or a filter screen formed therein so that the crushed material 2 remains and only the working fluid F is discharged.
[0095] Such a filter 32 may utilize fine pores at least smaller than the size of the pulverized material 2 or a filter formed at a pitch smaller than the size of the pulverized material 2 .
[0096] Therefore, when using such a filter 32, the pulverized material 2 and the working fluid F can be separated, and the pulverized material 2 can be filtered and only the working fluid F can be discharged. The filtered pulverized material 2 can be dried, incinerated, or discarded for separate management.
[0097] However, the filter 32 is not necessarily limited to the drawings, and filters in various forms such as sponge, fabric, non-woven fabric, etc. may also be applied.
[0098] Fig.10 2 is a cross-sectional view showing a substrate processing apparatus 200 according to some other embodiments of the present invention.
[0099] like Fig.10 As shown, a substrate processing device 200 according to some other embodiments of the present invention may include a guide member 40 , a waste crushing device 20 , and a filtering device 30 .
[0100] According to some other embodiments of the present invention, the substrate processing device 200 can crush and process the waste 1, which may be materials or defective products that cannot pass the inspection process in the semiconductor package cutting and sorting device 1000.
[0101] For example, the guide member 40 may be a hopper or a conveying pipe having a funnel shape as a whole, and guides the waste 1 dropped from the pickup head PH to the discharge port Cb.
[0102] For example, the waste pulverizing device 20 may be a device that pulverizes waste 1 generated during semiconductor production and discharged from the discharge port Cb into smaller sized pulverized products 2 of several centimeters or millimeters in size for easy handling, management or transportation.
[0103] The filter device 30 is a device that separates the pulverized material 2 pulverized into a smaller size, such as several centimeters or several millimeters, from the working fluid F such as ordinary air for easy handling, management or transportation, thereby filtering the pulverized material 2 and discharging only the working fluid F.
[0104] The working fluid F may be normal ambient air without additional supply, or may be water or working medium supplied by a separate supply device.
[0105] Therefore, according to the present invention, when the guide 40 guides the waste 1 dropped from the pickup head PH to the direction of the discharge port Cb, for example, the waste crushing device 20 can crush the waste 1 discharged from the discharge port Cb into smaller sizes, and the filtering device 30 separates the crushed material 2 crushed into smaller sizes from the working fluid F such as air, thereby filtering the crushed material 2 and discharging only the working fluid F to the outside.
[0106] Therefore, waste 1 such as materials or defective products that cannot pass the inspection process in the semiconductor packaging cutting and sorting device 1000 can be automatically crushed into smaller-sized crushed materials 2 and automatically discharged to the outside. Without relying on manual operation by an operator, the inside of the equipment can always be managed cleanly, thereby producing high-quality products, greatly saving working time and manpower, and maximizing production efficiency.
[0107] Fig.11 2 is a cross-sectional view showing a substrate processing apparatus 300 according to some other embodiments of the present invention.
[0108] like Figures 1 to 11 As shown, according to another embodiment of the present invention, the substrate processing device 300 described above Figure 2 The substrate processing device 100 and Fig.10 The exhaust pipes of the substrate processing apparatus 200 may be connected to each other to exhaust the working fluid into a separate tank T, or circulate it through a separate circulation line for reuse.
[0109] However, the substrate processing apparatus 300 according to another part of other embodiments of the present invention is not necessarily limited to the drawings and may be applied to various forms and kinds of apparatuses other than the semiconductor package cutting and sorting apparatus 1000 .
[0110] Therefore, it can not only handle Figure 1 The unnecessary parts remaining after cutting in the cutting module 2000 of the semiconductor package cutting and sorting device 1000 can also be processed in a unified manner as waste 1 such as materials or defective products that cannot pass the inspection in the semiconductor package conveying module 4000.
[0111] Fig.12 is a flow chart showing a substrate processing method according to some embodiments of the present invention.
[0112] like Figures 1 to 12 As shown, the substrate processing method according to some embodiments of the present invention includes: (a) a step of using a working fluid F to transport waste 1 generated in a semiconductor production process to an outlet Cb; (b) a step of crushing the waste 1 discharged from the outlet Cb into smaller sizes; and (c) a step of separating the crushed material 2 crushed into a smaller size from the working fluid F, thereby filtering the crushed material 2 and only discharging the working fluid F.
[0113] The step (b) may include: (b-1) crushing the waste 1 using the cutter 212 of the grinding pump 21; and (b-2) conveying the crushed material using the impeller 213 of the grinding pump 21.
[0114] In the step (c), a filter 32 may be used. The filter 32 is contained in the collection body 31 and has fine pores or a filter screen formed therein so that the pulverized material 2 remains and only the working fluid F is discharged.
[0115] Although the present invention has been described with reference to the embodiments shown in the accompanying drawings, this is merely exemplary, and those skilled in the art will appreciate that various modifications and equivalent other embodiments are possible. Therefore, the true technical protection scope of the present invention must be determined by the technical concept of the attached patent claims.
