[0043] [Example 1]
[0044] Please see Figures 1 to 4D As shown, this is an embodiment of the present invention. Figure 1 As shown, this embodiment discloses a laser die bonding device 1000, which includes a cyclic workstation S and multiple devices D located corresponding to the cyclic workstation S. The cyclic workstation S has multiple stations S' along a circular path, and the cyclic workstation S includes multiple acquisition devices S1 that move along the circular path. Each acquisition device S1 is light-transmitting and can pass through multiple stations S' one by one along the circular path.
[0045] In this embodiment, the ring path is circular, the number of multiple acquisition devices S1 is not less than (e.g., equal to) the number of multiple stations S', and the multiple acquisition devices S1 can operate synchronously at the multiple stations S' respectively, thereby improving the overall operating efficiency of the laser die bonding device 1000, but the present invention is not limited thereto.
[0046] More specifically, each of the stations S' is, for example, a work area, and the multiple stations S' have different but related functions and distinct area sizes. In this embodiment, the multiple stations S' sequentially include a chip supply station S100, an adhesive station S200, a chip calibration station S300, and a die bonding station S400 along the circular path (that is, the chip calibration station S300 is located between the adhesive station S200 and the die bonding station S400), but the invention is not limited thereto. For example, in other embodiments not shown in this invention, the number and order of the multiple stations S' can be increased or decreased according to requirements.
[0047] Furthermore, in this embodiment, the plurality of devices D include a chip supply device 100 located at the chip supply station S100, an adhesive supply device 200 located at the adhesive station S200, a chip calibrator 300 located at the chip calibration station S300, and a die bonding device 400 located at the die bonding station S400, but the present invention is not limited thereto.
[0048] For example, in other embodiments of the present invention not shown, a portion of the plurality of stations S' (e.g., the chip calibration station S300) and their corresponding devices D (e.g., the chip calibrator 300) may be reduced according to design requirements; or, the laser die bonding device 1000 may also be equipped with new stations and their corresponding devices according to design requirements.
[0049] To facilitate understanding of the specific operation of the laser-type die bonding device 1000 in this embodiment, the function and purpose of each device D and its corresponding station S' are described below. The operation process of multiple acquisition devices S1 is the same, so the accompanying drawings of this embodiment only illustrate the operation of one acquisition device S1, but the present invention is not limited thereto.
[0050] like Figure 1 As shown, the chip supply device 100 can continuously supply chips C for any of the acquirers S1 to acquire; that is, the chip supply device 100 corresponds to the chip supply station S100 by its position, so that any of the acquirers S1 that moves to the chip supply station S100 can acquire one chip C.
[0051] Furthermore, such as Figures 2A to 2CAs shown, the glue supply 200 is located downstream of the chip supply station S100, and the glue supply 200 corresponds to the adhesive station S200 in its position, so that any of the pickers S1 moving to the adhesive station S200 can adhere a chip C to a glue G (that is, the picker S1 is used to pick up a chip C and adhere it with glue G). More specifically, in this embodiment, the glue supply 200 may be a container filled with glue, and the picker S1 can move the chip C it has picked up toward the glue supply 200 to adhere the glue G.
[0052] like Figure 3 As shown, the chip calibrator 300 is located downstream of the adhesive supply 200, and its position corresponds to the chip calibration station S300, used to correct the position of the chip C that has moved to any of the pickups S1 at the chip calibration station S300. The chip calibrator 300 can be used to correct the chip C with the adhesive G adhered to it (e.g., ...). Figure 2C The location of the crystal is such that it facilitates the precise execution of subsequent crystal bonding operations.
[0053] like Figures 4A to 4D As shown, the die bonding device 400 includes a fixed laser emitter 1, a support stage 2, a substrate camera 3, and a photomask unit 4. The fixed laser emitter 1 is, for example, a laser-assisted bonder (LAB) system, and is located downstream of the chip calibrator 300 (i.e., the chip calibrator 300 is upstream of the fixed laser emitter 1). Furthermore, the fixed laser emitter 1 is located at a predetermined position and defines a light emission path P. That is, in this embodiment, the fixed laser emitter 1 will not move away from the predetermined position, excluding any moving laser emitters.
[0054] The support platform 2 is used to support at least one substrate B, and in the accompanying drawings of this embodiment, the support platform 2 is used to support multiple substrates B. However, for ease of explanation, the following only describes the case where the support platform 2 supports one substrate B. The support platform 2 is movable relative to the fixed laser emitter 1 so that one substrate B is located on the light emission path of the fixed laser emitter 1. Furthermore, the position of the substrate camera 3 corresponds to the die bonding station S400, and is used to obtain the position of the substrate B located on the support platform 2.
[0055] The photomask unit 4 includes at least one photomask 41 located on the light emission path P. In this embodiment, the number of photomasks 41 included in the photomask unit 4 is described as multiple, but the invention is not limited thereto. The multiple photomasks 41 have different patterns, and one of the multiple photomasks 41 can be selectively moved onto the light emission path P of the fixed laser emitter 1.
[0056] The positions of the fixed laser emitter 1, the carrier stage 2, the substrate camera 3, and the photomask unit 4 described above all correspond to the die bonding station S400, so that the die bonding station S400, by being positioned corresponding to the fixed laser emitter 1, allows any of the acquisition devices S1 that move there to press the chip C it has acquired, and causes the chip C to adhere to the substrate B located on the light emission path P through the colloid G (that is, the acquisition device S1 can be used to move the chip C with the colloid G adhered to it, so that the colloid G adheres to the substrate B located on the light emission path).
[0057] In the die bonding station S400, the fixed laser emitter 1 emits a laser beam that passes through at least one photomask 41 along the light emission path P and through one of the pickups S1 before being projected onto the chip C. Alternatively, when the chip C is attached to the substrate B located on the light emission path P with the colloid G, the pickup S1 presses the chip C against the substrate B, and the fixed laser emitter 1 emits a laser beam that passes through at least one photomask 41 along the light emission path P and through the pickup S1 before being projected onto the chip C.
[0058] Accordingly, the laser die bonding equipment 1000 disclosed in this embodiment presses the chip C against the substrate B through the acquisition device S1, and uses the fixed laser emitter 1 in conjunction with at least one photomask 41 to cure the colloid G located between the chip C and the substrate B, thereby replacing the curing method of heating the ambient temperature, and thus effectively improving the operation and production efficiency of the laser die bonding equipment 1000.
[0059] Furthermore, the laser die bonding equipment 1000 disclosed in this embodiment uses a fixed laser emitter 1 that does not move, which reduces the alignment difficulty during the curing process of the colloid G and facilitates the use of a larger and more powerful laser emitter, thereby further improving the operation and production efficiency of the laser die bonding equipment 1000.
[0060] Furthermore, in the die bonding station S400, multiple photomasks 41 can be moved sequentially onto the light emission path P, so that the laser beam emitted from the fixed laser emitter 1 can pass through at least two photomasks 41 at different times, and pass through the collector S1 with different light shapes and be projected onto the chip C. In other words, when the chip C is attached to the substrate B located on the light emission path P with the colloid G, multiple photomasks 41 can be moved sequentially onto the light emission path P, so that the laser beam emitted from the fixed laser emitter 1 can pass through at least two photomasks 41 at different times, and pass through the collector S1 with different light shapes (e.g., at least two light shapes) and be projected onto the chip C.
[0061] Furthermore, in this embodiment, the plurality of photomasks 41 are configured according to design requirements and allow the laser beam to pass through to form various light shapes with different functions. For example, among at least two light shapes that pass through the acquisition unit S1 and are projected onto the chip C, the first light shape is used to focus and solidify the outer portion of the colloid G, while the second light shape is used to focus and solidify the inner portion of the colloid G, thereby enabling the colloid G to be solidified gradually and stably from the outside in.
[0062] It should be further noted that, in this embodiment, the laser die bonding device 1000 is described using a cyclic workstation S in conjunction with a plurality of corresponding devices D, but the present invention is not limited thereto. For example, in other embodiments of the present invention not shown, the laser die bonding device 1000 may also include the fixed laser emitter 1, at least one photomask 41, the support stage 2, and the acquisition device S1; that is, the laser die bonding device 1000 may operate through at least one acquisition device S1 but may not have the cyclic workstation S.
[0063] [Example 2]
[0064] Please see Figure 5 As shown, this is Embodiment Two of the present invention. Since this embodiment is similar to Embodiment One described above, the similarities between the two embodiments will not be repeated. The differences between this embodiment and Embodiment One are roughly explained as follows:
[0065] In this embodiment, the die bonding device 400 does not include any of the photomasks 41, and the cyclic workstation S preferably includes a plurality of photomasks S2, the number of which is equal to the number of the plurality of acquirers S1. Each acquirer S1 has a head S11 for acquiring the chip C, and each acquirer S1 forms a slot S12 adjacent to the head S11, and any photomask S2 can be detachably inserted into the slot S12 of one acquirer S1.
[0066] [Example 3]
[0067] Please see Figure 6 As shown, this is Embodiment 3 of the present invention. Since this embodiment is similar to Embodiment 1 described above, the similarities between the two embodiments will not be repeated. The differences between this embodiment and Embodiment 1 are roughly explained as follows:
[0068] In this embodiment, the die bonding device 400 does not include any of the photomasks 41, and the cyclic workstation S preferably includes a plurality of photomasks S2, the number of which is equal to the number of the plurality of acquirers S1. Each acquirer S1 has a head S11 for acquiring the chip C, and each photomask S2 is disposed within one acquirer S1 and adjacent to the head S11.
[0069] [Example 4]
[0070] Please see Figure 7 As shown, this is Embodiment Four of the present invention. Since this embodiment is similar to Embodiments One to Three described above, the similarities between these embodiments will not be repeated. The differences between this embodiment and the above embodiments are roughly explained as follows:
[0071] In this embodiment, each of the acquisition devices S1 further includes a chip heater S13 adjacent to the head S11, and the chip heater S13 is annular and disposed outside the light emission path P, so that the acquisition device S1 can heat the chip C by the chip heater S13 before the acquisition device S1 presses the chip C against (or attaches it to) the substrate 2.
[0072] Furthermore, the carrier stage 2 may also be provided with a substrate heater 21, so that the carrier stage 2 can heat the substrate B by the substrate heater 21 before the acquirer S1 presses the chip C against (or attaches it to) the substrate 2.
[0073] Accordingly, the chip C and the substrate B can be heated to a default temperature by the chip heater S13 and the substrate heater 21, respectively. Then, the acquirer S1 presses the chip C against the substrate 2 so that the chip C and the substrate 2 can be connected at the default temperature, thereby improving the efficiency, stability and accuracy of the connection.
[0074] Furthermore, in this embodiment, the laser die bonding apparatus 1000 is described with both the chip heater S13 and the substrate heater 21 simultaneously provided, but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the laser die bonding apparatus 1000 may only have one of the chip heater S13 and the substrate heater 21. Furthermore, the chip heater S13 may also be configured in any of the acquisition devices S1 described in Embodiment 1 or Embodiment 2.
[0075] [Technical Effects of Embodiments of the Invention]
[0076] In summary, the laser die bonding equipment disclosed in the embodiments of the present invention presses the chip against the substrate using the pickup device and cures the colloid located between the chip and the substrate using the fixed laser emitter, thereby improving the curing method of the heating environment temperature and effectively improving the operation and production efficiency of the laser die bonding equipment.
[0077] Furthermore, the laser die bonding equipment disclosed in the embodiments of the present invention uses a fixed laser emitter that does not move, which reduces the alignment difficulty in the colloid curing process and facilitates the use of a larger and more powerful laser emitter, thereby further improving the operation and production efficiency of the laser die bonding equipment.
[0078] Furthermore, the at least one photomask of the laser die bonding device disclosed in the embodiments of the present invention, which is used in conjunction with the fixed laser emitter, can be constructed according to design requirements (e.g., multiple photomasks allow one of the photomasks to be selectively moved onto the light output path; or, at least one photomask can be detachably inserted into the slot of the acquirer; or, at least one photomask is disposed within the acquirer), thereby enabling the laser die bonding device to have a wider range of applications.
