AI Technical Summary
The prior art cannot adjust the posture of the optical fiber array element after coupling the optical fiber array element with the integrated circuit element, resulting in poor coupling effect.
The optical fiber array element is held by a holding mechanism, and its posture is adjusted before the first adhesive is cured to ensure that the optical signal intensity is within a preset range. The optical signal intensity is monitored in real time using a multi-axis moving gantry mechanism and a measuring unit to adjust the position and posture of the optical fiber array element.
It achieves efficient coupling between optical fiber array elements and integrated circuit elements, improves coupling effect and stability, and ensures the intensity and consistency of optical signal transmission.

Abstract
Description
Technical Field
[0001] The present invention relates to a device coupling method and device, and more particularly to a device coupling method and device for coupling an optical fiber array device to an integrated circuit device. Background Art
[0002] In order to produce chips with higher transmission efficiency and lower power consumption in the semiconductor process, silicon photonics (SiPh; Silicon Photonics) technology has become a key focus of industrial development. In silicon photonics technology, whether it is pluggable transceiver optics (PTO; Pluggable Transceiver Optics), on-board optical architecture (OBO; On-Board Optics), co-packaged optical architecture (CPO; Co-Packaged Optics) or optical I / O architecture (Optical I / O), it is necessary to couple fiber array elements (FAU; Fiber Array Unit) to integrated circuit components (IC; Integrated Circuit). Currently, semiconductor processes have evolved to 2.5D or 3D packaging. Integrated circuit components and fiber array components have also changed in structure to match the process evolution. For example, integrated circuit components are equipped with photonic integrated circuits (PIC; Photonic Integrated Circuit) The optical fiber array element is provided with an optical coupler, a socket, and an optical fiber connected between the optical coupler and the socket. The photonic integrated circuit of the integrated circuit element is coupled to the optical coupler of the optical fiber array element and optically communicates with the outside world via the optical fiber and the socket of the optical fiber array element.
[0003] When coupling the optical fiber array element to the integrated circuit element, a multi-axis movable gantry mechanism is typically used to hold the optical fiber array element and adhere the optical fiber array element to the integrated circuit element using adhesive. However, prior art techniques do not allow the optical fiber array element to be moved after the gantry mechanism adheres the optical fiber array element to the integrated circuit element, making it impossible to adjust the position of the optical fiber array element according to the situation. This requires further improvement. Summary of the Invention
[0004] Therefore, an object of the present invention is to provide a device coupling method that can improve at least one disadvantage of the prior art.
[0005] Another object of the present invention is to provide a component coupling device that can be used to perform the component coupling method.
[0006] The component coupling method according to the present invention includes: providing a fiber array component having an optical coupling portion; providing an integrated circuit component having a photonic integrated circuit; causing a holding mechanism to hold the fiber array component and adhere the optical coupling portion of the fiber array component to the photonic integrated circuit via a first adhesive; causing the holding mechanism to continue holding the fiber array component and measure an intensity of an optical signal transmitted between the fiber array component and the integrated circuit component; causing the holding mechanism to continue holding the fiber array component and adjust the posture of the fiber array component according to the intensity value until the intensity value falls within a predetermined range, and then curing the first adhesive.
[0007] According to another aspect of the present invention, a component coupling apparatus can be used to perform the component coupling method.
[0008] In the device coupling method and apparatus of the embodiments of the present invention, after the optical coupling portion is bonded to the photonic integrated circuit via the first adhesive, the holding mechanism continues to hold the optical fiber array component and adjusts the posture of the optical fiber array component as needed before the first adhesive cures. This overcomes the disadvantage of prior art that the posture of the optical fiber array component cannot be adjusted after bonding to the integrated circuit component.

[0224] See also Figure 7 、 25 The glue coating station 10 is located on a side of the second stage device 5 away from the inspection station 6 and is located within the range where the component coupling device 2 can perform operations;
[0225] The glue coating station 10 is equipped with a first glue valve 101 for coating the first glue material F1 and a second glue valve 102 for coating the first glue material F2. The first glue valve 101 is equipped with a first glue nozzle 1011 for dispensing glue upward, and the second glue valve 102 is equipped with a second glue nozzle 1021 for dispensing glue upward.

Alternatively, screw glue valves, piezoelectric glue valves, spray glue valves, etc. can be used.
[0226] In the implementation of the component coupling method according to an embodiment of the present invention, the first tray S1 carries at least one integrated circuit component W2 (in this embodiment of the present invention, one component) and is fed into the first track 71 from one end of the first track device 7. The second tray S2 carries at least one optical fiber array component W1 (in this embodiment of the present invention, multiple components) and is fed into the second track 81 from one end of the second track device 8.
[0227] The first rail 71 and the second rail 81 respectively transport the first tray S1 and the second tray S2 to the bottom of the gantry 91, and the first platform 41 and the second platform 51 are respectively driven by the first platform rail seat 43 and the second platform rail seat 52 to the bottom of the gantry 91;
[0228] The first pick-and-place mechanism 92 of the component transfer device 9 is moved to the first tray S1 to extract the integrated circuit component W2 onto the first carrier 41 , and the second pick-and-place mechanism 93 is moved to the second tray S2 to extract the optical fiber array component W1 onto the second carrier 51 .
[0229] After the first carrier 41 and the second carrier 51 respectively carry the integrated circuit device W2 and the optical fiber array device W1, the first carrier 41 and the second carrier 51 are driven by the first carrier rail 43 and the second carrier rail 52 to the bottom of the second direct-acting component A2 of the first driving mechanism A.
[0230] The first driving mechanism A drives the inspection mechanism D to move laterally above the first stage 41 , and the inspection mechanism D obtains the orientation of the photonic integrated circuit W23 and / or the lens array W231 and the flatness of the upper surface of the photonic integrated circuit W23 , and then the control unit 3 records the obtained orientation.
[0231] After obtaining the orientation of the photonic integrated circuit W23 and / or the lens array W231 and the flatness of the upper surface of the photonic integrated circuit W23, the first driving mechanism A drives the second driving mechanism B to link the holding mechanism C to move horizontally to above the second carrier 51, and the first driving mechanism A drives the second driving mechanism B to link the holding mechanism C to move downward so that the holding member C2 contacts the optical fiber array element W1 on the second carrier 51, and at the same time, the negative pressure source turns on the negative pressure so that the first holding portion C21 and the second holding portion C22 of the holding member C2 respectively adsorb the optical coupling portion W11 and the socket portion W12 of the optical fiber array element W1, and then the driving component C4 drives the docking member C3 to approach the optical fiber array element W1 and dock with the optical fiber array element W1, so that the measuring unit 1 can supply the optical signal W3 to the optical fiber array element W1;
[0232] After the docking member C3 is docked with the optical fiber array element W1, the first driving mechanism A drives the second driving mechanism B to link the holding mechanism C to move upward, so that the holding member C2 adsorbs and holds the optical fiber array element W1 and moves it away from the second carrier 51, and the first driving mechanism A drives the second driving mechanism B to link the holding mechanism C to drive the optical fiber array element W1 to move horizontally to the detection station 6 for inspection and measurement of the intensity value of the optical signal W3, and obtains the orientation of the optical coupling part W11 and / or the prism W111 and the flatness of the lower surface of the optical coupling part W11 and the measured optical signal at the detection station 6. The intensity value of the signal W3 is then recorded by the control unit 3; wherein, the control unit 3 can compare the deviation between the orientation of the optical coupling portion W11 and / or the prism W111 and the orientation of the photonic integrated circuit W23 and / or the lens array W231, and control the first rotating component B1 of the second driving mechanism B to swing left and right in an arc path with the first axis L1 as the axis with reference to the deviation, so as to adjust the posture of the optical fiber array element W1 held by the holding mechanism C so that the orientation of the optical coupling portion W11 and / or the prism W111 can correspond to the orientation of the photonic integrated circuit W23 and / or the lens array The control unit 3 can compare the deviation between the flatness of the lower surface of the optical coupling portion W11 and the flatness of the upper surface of the photonic integrated circuit W23, and control the second rotating component B2 of the second driving mechanism B to swing in an upward and downward arc path with the second axis L2 as the axis center according to the deviation, and control the third rotating component B3 to swing in a forward and backward arc path with the third axis L3 as the axis center, so as to adjust the posture of the optical fiber array element W1 held by the holding mechanism C so that the lower surface of the optical coupling portion W11 can be parallel to the upper surface of the photonic integrated circuit W23; and the control unit The unit 3 records the intensity value of the optical signal W3 measured by the detection station 6 for calibration purposes. This is because optical loss may occur during the transmission of the optical signal W3. For example, the measurement unit 1 supplies the optical signal W3 with an intensity value of 100 units to the optical fiber array element W1, but the optical integrator 63 actually measures the intensity value of the optical signal W3 transmitted from the optical fiber array element W1 as 90 units. The control unit 3 will record the intensity value of the optical signal W3 measured by the detection station 6 as 90 units and use it for subsequent readjustment of the posture (orientation or level) of the optical fiber array element W1.
[0233] After the second driving mechanism B drives the holding mechanism C to adjust the posture of the optical fiber array element W1, the first driving mechanism A drives the second driving mechanism B, which in turn moves the holding mechanism C laterally to the glue coating station 10 for glue coating. The holding mechanism C can hold the optical fiber array element W1 and move it relative to the first glue valve 101 and the second glue valve 102 along the second direction d2, so that the first glue valve 101 and the second glue valve 102 respectively coat the lower surface of the optical coupling portion W11 and the lower surface of the socket portion W12 with a layer of the first glue F1 and a layer of the second glue F2.
[0234] After the optical fiber array element W1 is coated with glue, the first driving mechanism A drives the second driving mechanism B to move the holding mechanism C horizontally to the top of the first carrier 41. Because the second driving mechanism B has previously driven the holding mechanism C to adjust the orientation of the optical coupling portion W11 and / or the prism W111 to correspond to the orientation of the photonic integrated circuit W23 and / or the lens array W231, and the lower surface of the optical coupling portion W11 has been adjusted to be parallel to the upper surface of the photonic integrated circuit W23, after the holding mechanism C is above the first carrier 41, the first driving mechanism A can be directly driven to move the second driving mechanism B to the top of the first carrier 41. The driving mechanism A drives the second driving mechanism B, which in turn moves the holding mechanism C downward, causing the lower surface of the optical coupling portion W11 and the lower surface of the socket portion W12 to adhere to the upper surface of the photonic integrated circuit W23 and the upper surface of the second cover portion W222 of the cover W22 via the first adhesive F1 and the second adhesive F2, respectively, so that the optical signal W3 can be transmitted between the optical fiber array element W1 and the integrated circuit element W2 via the prism W111 and the lens array W231. At this time, the holding mechanism C continues to hold the optical fiber array element W1 via the holding member C2.
[0235] After the optical fiber array element W1 is adhered to the integrated circuit element W2, because the first adhesive F1 and the second adhesive F2 have not yet solidified and the first adhesive F1 and the second adhesive F2 have a certain height, the optical fiber array element W1 can float on the first adhesive F1 and the second adhesive F2 and can still be adjusted by the holding mechanism C; at this time, the measuring unit 1 can measure whether the intensity value of the optical signal W3 falls within a preset range. When the intensity value of the optical signal W3 does not fall within the preset range, the control unit 3 controls the second driving mechanism B to drive the holding mechanism C to drive the optical fiber array element W1 to the axis according to demand. The point Lp is used as the rotation center to perform three-degree-of-freedom rotation about the first axis L1, the second axis L2, and the third axis L3. The posture of the optical fiber array element W1 is slightly adjusted while the optical fiber array element W1 is adhered to the integrated circuit element W2. The second driving mechanism B is controlled to stop actuating when the intensity value of the optical signal W3 measured by the measuring unit 1 falls within the preset range. When the intensity value of the optical signal W3 falls within the preset range, it indicates that the optical signal W3 transmitted between the optical fiber array element W1 and the integrated circuit element W2 has a better transmission efficiency. The preset range is consistent with the range in which the optical fiber array element W1 is adhered to the integrated circuit element W2. The detection station 6 has recorded a positive correlation with the intensity value of the optical signal W3 in the control unit 3. For example, the intensity value of the optical signal W3 has been recorded as 90 units. Considering that optical loss occurs during the transmission of the optical signal W3 between the optical fiber array element W1 and the integrated circuit element W2, the preset range can be preset between 80 and 90 units. If the intensity value of the optical signal W3 measured by the measuring unit 1 is 75 units, the control unit 3 controls the second driving mechanism B to continuously drive the holding mechanism C to adjust the posture of the optical fiber array element W1 until the optical signal W3 measured by the measuring unit 1 is 75 units. The intensity value of the optical signal W3 falls between 80 and 90 units; wherein the first rotating assembly B1, the second rotating assembly B2, and the third rotating assembly B3 of the second driving mechanism B are actuated in the order of the third rotating assembly B3 first, followed by the second rotating assembly B2, and finally the first rotating assembly B1; if the intensity value of the optical signal W3 measured by the measuring unit 1 falls within the preset range after the third rotating assembly B3 drives the holding mechanism C to cause the optical fiber array element W1 to rotate about the third axis L3, then the first rotating assembly B1 and the second rotating assembly B2 do not need to be actuated again;After the second driving mechanism B drives the holding mechanism C to slightly adjust the posture of the optical fiber array element W1, if the intensity value of the optical signal W3 still cannot fall within the preset range, the control unit 3 can control the first driving mechanism A to drive the second driving mechanism B to link the holding mechanism C to drive the optical fiber array element W1 to perform linear movement with three degrees of freedom along the first direction d1, the second direction d2, and the second direction d3, and continue to control the second driving mechanism B to drive the holding mechanism C to drive the optical fiber array element W1 to perform rotational movement with three degrees of freedom about the first axis L1, the second axis L2, and the third axis L3 as axes, thereby adjusting the posture of the optical fiber array element W1 to a greater extent while the optical fiber array element W1 is adhered to the integrated circuit element W2, and controlling the first driving mechanism A and the second driving mechanism B to stop operating until the intensity value of the optical signal W3 measured by the measuring unit 1 falls within the preset range;
[0236] After the intensity of the optical signal W3 falls within the preset range, the curing assembly A5 uses the ultraviolet light C511 and the laser to cure the first adhesive F1 and the second adhesive F2, respectively. Because the optical coupler W11 is made of a light-transmitting material, the ultraviolet light C511 can penetrate the optical coupler W11 and cure the first adhesive F1 between the optical coupler W11 and the photonic integrated circuit W23. Furthermore, because the laser can generate heat, the second adhesive F2 between the socket W12 and the second cover W222 of the cover W22 is heated and cured.
[0237] After the first adhesive material F1 and the second adhesive material F2 are cured, the driving assembly C4 drives the docking member C3 away from the optical fiber array element W1 to release the docking with the optical fiber array element W1;
[0238] After the docking member C3 is released from the docking with the optical fiber array element W1, the negative pressure source turns off the negative pressure and moves the retaining member C2 away from the optical fiber array element W1, thereby completing the process of coupling the optical fiber array element W1 to the integrated circuit element W2;
[0239] The first driving mechanism A and the second driving mechanism B of the element coupling device 2 can drive the holding mechanism C to repeat the above-mentioned actions in sequence to couple a preset number of the optical fiber array elements W1 to the integrated circuit element W2; when the photonic integrated circuit W23 is arranged on the four proximal sides of the carrier W21 of the integrated circuit element W2, the two element coupling devices 2 can respectively perform the operation of coupling the optical fiber array element W1 to the integrated circuit element W2 on two opposite proximal sides of the four proximal sides of the integrated circuit element W2, and after the coupling operation is completed on the two opposite proximal sides, the first rotating seat 42 drives the first carrier 41 to rotate 90 degrees , and then use the two component coupling devices 2 to continue to perform coupling operations on the other two proximal sides opposite to the integrated circuit component W2; after the integrated circuit component W2 has coupled a preset number of the optical fiber array components W1, the first carrier 41 is driven by the first carrier rail seat 43 to return to the bottom of the gantry 91, and the first pick-and-place mechanism 92 extracts the integrated circuit component W2 that has completed the coupling operation and returns it to the first material tray S1, and then sends it out of the first track 71 from the other end of the first track device 7; after the optical fiber array component W1 is no longer on the second material tray S2, the second material tray S2 will be sent out of the second track 81 from the other end of the second track device 8.
[0240] In the device coupling method and apparatus of the embodiments of the present invention, after the optical coupling portion W11 is adhered to the photonic integrated circuit W23 via the first adhesive F1, the holding mechanism C continues to hold the optical fiber array device W1 and adjusts the posture of the optical fiber array device W1 as needed before the first adhesive F1 solidifies. This overcomes the disadvantage of the prior art that the posture of the optical fiber array device W1 cannot be adjusted after the optical fiber array device W1 is adhered to the integrated circuit device W2.
