Description

Technical Field

[0001] This invention belongs to the field of developer detection technology, specifically relating to an automatic developer detection device and its detection method. Background Technology

[0002] Developers are indispensable key chemicals in semiconductor manufacturing, printing plate making, and photolithography. Their concentration, activity, and other quality parameters directly determine the quality of the developing effect, thus affecting the precision and performance of the final product. Therefore, it is crucial to conduct rapid and accurate quality testing of developers before use and during mass production.

[0003] Traditional developer quality testing often relies on manual methods. Workers hold the test piece, immersing it in the developer for a certain time before removing it. Then, another standard test piece is immersed in the standard developer. Finally, the quality of the developer is determined by visually comparing the clarity of lines and other indicators on the two sets of test pieces. However, developers are often highly corrosive and irritating; direct contact can easily cause damage to the skin and respiratory tract, posing serious safety hazards. Furthermore, in manual operation, parameters such as immersion time, removal speed, and rinsing degree are difficult to maintain consistently, leading to subjective errors in the test results and affecting the accuracy of the assessment.

[0004] Therefore, semi-automated developer testing equipment has gradually emerged in existing technologies. This equipment uses mechanical structures to simulate manual operation processes, eliminating the need for workers to directly contact the developer and thus avoiding the risk of corrosive damage. However, the processing of the test piece and the standard sample requires two independent operations, or direct comparison with the existing standard sample. But the developing effect of the developer is easily affected by environmental changes, or differences in operating parameters can lead to inconsistent comparison benchmarks, affecting the reliability of the test results. Furthermore, existing test pieces and standard samples use different carriers, requiring frequent switching during comparison, further increasing operational complexity and the probability of error.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: Specific embodiments, such as Figures 1-5 As shown, the present invention provides an automatic developer detection device, including a developer storage tank 2, a rinsing tank 3, and a standard developer storage tank 4 disposed on a workbench 1. The workbench 1 is also provided with a mechanical gripper 5 and a moving mechanism 6. The test piece 7 is provided with a detection part 702 and a standard part 703. The mechanical gripper 5 clamps the test piece 7 and has the freedom to reciprocate between the developer storage tank 2, the rinsing tank 3, and the standard developer storage tank 4 by means of the moving mechanism 6. The detection part 702 of the test piece 7 is moved to the developer storage tank 2 for immersion by means of the mechanical gripper 5, and the standard part 703 of the test piece 7 is moved to the standard developer storage tank 4 for immersion by means of the mechanical gripper 5.

[0022] Existing semi-automated developer testing equipment uses mechanical structures to simulate manual operation processes, eliminating the need for workers to directly contact the developer and thus avoiding the risk of corrosion damage. However, the processing of the test piece 7 and the standard test piece requires two independent operations, or the existing standard test piece can be directly compared with the test piece 7. However, the developing effect of the developer is easily affected by environmental changes (such as temperature and humidity), or the difference in operating parameters may lead to inconsistencies in the comparison benchmark, affecting the reliability of the test results. In addition, the existing test piece 7 and the standard test piece are on different carriers, requiring frequent switching during comparison, further increasing the operational complexity and the probability of error.

[0023] Therefore, in this invention, a detection unit 702 and a standard unit 703 are integrated on the test piece 7. The detection unit 702 is moved separately to the test developer tank 2 for immersion, and the standard unit 703 is moved separately to the standard developer tank 4 for immersion. This allows the same test piece to undergo two types of developer treatment in a short period of time, ensuring that the environmental parameters such as temperature are basically the same during the immersion process of the standard test piece and the test piece 7. Furthermore, the comparison can be completed without replacing the test piece, reducing detection errors caused by individual differences in the test pieces and facilitating subsequent comparative observation by staff.

[0024] At the same time, due to the mechanical operation by the mechanical claw 5, the detection part 702 and the standard part 703 can be standardized in the immersion angle and other operation parameters in the developing solution by a standard 90° rotation, and the mechanical detection process does not require manual intervention and is suitable for batch detection requirements.

[0025] The to-be-tested sheet 7 further comprises a main body part 701, and the detection part 702 and the standard part 703 are respectively adjacent to the main body part 701 and jointly form an L-shaped structure, and a sample test tube 8 is further arranged on the main body part 701, the sample test tube 8 is filled with a to-be-tested developing solution, and the sample test tube 8 is in plug-in cooperation with the main body part 701 through a mounting hole on the main body part 701.

[0026] The L-shaped structure of the to-be-tested sheet 7 makes the detection part 702 and the standard part 703 independent of each other, and the two do not interfere with each other when being immersed in the corresponding developing solution, and the mechanical claw 5 has a simple movement track when switching the positions of the detection part 702 and the standard part 703, and only needs to be rotated by 90°, without complex operation.

[0027] In addition, in the present application, the space region on the main body part 701 is used to directly plug and fix the sample test tube 8 filled with the to-be-tested developing solution to the to-be-tested sheet 7, since the sample test tube 8 is pasted with information corresponding to the to-be-tested developing solution, the subsequent staff can check and record the detection information, further improving the detection efficiency, and the problem of confusion of information of different batches of to-be-tested developing solutions is less likely to occur, which is suitable for batch detection requirements.

[0028] The sample test tube 8 comprises a tube body and a tube cover, and a sealing gasket is arranged between the tube body and the tube cover, and a liquid taking hole is arranged on the tube cover.

[0029] The sealing gasket seals the to-be-tested developing solution in the tube body, avoids the to-be-tested developing solution from dripping along the tube opening and polluting the experimental environment during the transfer process, and also prevents the performance of the to-be-tested developing solution from changing due to air oxidation.

[0030] The workbench 1 is further provided with a liquid taking needle cylinder 9 and a push-pull assembly 10, the liquid taking needle cylinder 9 is connected with the moving mechanism 6 through the push-pull assembly 10, the needle tip of the liquid taking needle cylinder 9 is moved to the liquid taking hole of the sample test tube 8 by the moving mechanism 6 and extends into the tube body through the sealing gasket, and the to-be-tested developing solution in the tube body is extracted by the liquid taking needle cylinder 9 through the pulling of the push-pull assembly 10.

[0031] When taking liquid, first, the mechanism 6 cooperates with the mechanical claw 5 to grab the preset grabbing point of the test piece 7, and then through a series of operations such as rotation, swinging, moving, etc., the liquid taking hole of the sample test tube 8 is aligned with the needle tip of the liquid taking needle cylinder 9, at this time, the push-pull assembly 10 pulls the piston of the liquid taking needle cylinder 9 outward, so that the liquid taking needle cylinder 9 extracts the test developing liquid in the sample test tube 8, and then the liquid taking needle cylinder 9 is separated from the sample test tube 8 and moves to above the test developing liquid storage tank 2, at this time, the push-pull assembly 10 pushes the piston of the liquid taking needle cylinder 9 inward, so that the extracted test developing liquid is discharged into the test developing liquid storage tank 2, and then the mechanical claw 5 performs a series of operations such as rotation, swinging, moving, etc., so that the detection part 702 of the test piece 7 is immersed in the test developing liquid in the test developing liquid storage tank 2. Through this method, the matching consistency of the label information and the test developing liquid is ensured, the detection result is avoided to be confused, and the manual participation in the adding process of the test developing liquid is avoided.

[0032] The push-pull assembly 10 comprises a support seat 1001, a lead screw 1002, a guide rod 1003, a pulling block 1004 and a driving motor 1005 arranged on the support seat 1001, the lead screw 1002 passes through one end of the pulling block 1004 and is threadedly connected with the pulling block 1004, the guide rod 1003 passes through the other end of the pulling block 1004 and is slidably connected with the pulling block 1004, the driving motor 1005 drives the lead screw 1002 to rotate and drives the pulling block 1004 to reciprocatingly move along the guide rod 1003, the needle cylinder of the liquid taking needle cylinder 9 is fixedly connected with the support seat 1001, and the piston of the liquid taking needle cylinder 9 is fixedly connected with the pulling block 1004 and reciprocatingly moves by means of the pulling block 1004.

[0033] The present application utilizes the lead screw 1002 to accurately control the moving distance of the piston of the liquid taking needle cylinder 9, ensures that the extraction amount of the test developing liquid in each liquid taking needle cylinder 9 is consistent, and makes the developing liquid consumption parameter in the detection process controllable.

[0034] The mechanical claw 5 is rotationally connected with the moving mechanism 6 by means of the rotating disc 11, and the detection part 702 and the standard part 703 of the test piece 7 have vertical downward freedom degrees by means of the rotation of the mechanical claw 5.

[0035] When the detection part 702 needs to be immersed, the rotating disc 11 is rotated to make the detection part 702 vertically downward, and when the standard part 703 needs to be immersed, the rotating disc 11 is rotated by 90° to make the standard part 703 vertically downward, so that the immersion switching of the two functional parts can be realized without adjusting the position of the moving mechanism 6, and the operation time is shortened.

[0036] Meanwhile, the clamping point of the mechanical claw 5 is arranged at the right angle of the to-be-tested sheet 7, so as to ensure that the distance between the rotating center and the detection part 702 and the standard part 703 is consistent, and the vertical height of the standard part 703 is consistent with the vertical height of the detection part 702 before rotation after the to-be-tested sheet 7 rotates 90°.

[0037] The moving mechanism 6 comprises longitudinal rails 601, a transverse rail 602 and a vertical rail 603. The longitudinal rails 601 are symmetrically arranged on both sides of the workbench 1 by means of supports. The transverse rail 602 is horizontally arranged on the longitudinal rails 601 on both sides. The two ends of the transverse rail 602 are respectively slidably connected with the longitudinal rails 601 by means of first sliding seats 604 and have the freedom of moving along the X-axis direction. The vertical rail 603 is slidably connected with the transverse rail 602 by means of second sliding seats 605 and has the freedom of moving along the Y-axis direction. The mechanical claw 5 is slidably connected with the vertical rail 603 by means of third sliding seats 606 and has the freedom of moving along the Z-axis direction. The mechanical claw 5 has the freedom of reciprocating along the X, Y and Z axes by means of the moving mechanism 6.

[0038] The moving mechanism 6 comprises a three-dimensional rail system composed of the longitudinal rails 601, the transverse rail 602 and the vertical rail 603, so as to realize the accurate movement of the mechanical claw 5 in the three-dimensional space and accurately reach the position above any tank on the workbench 1, thereby ensuring that the to-be-tested sheet 7 can be accurately immersed in the tank or moved to the washing tank 3 for processing.

[0039] The workbench 1 is further provided with a sewage tank 12. The to-be-tested developer tank 2, the washing tank 3 and the standard developer tank 4 are respectively connected with the sewage tank 12 by means of sewage discharge pipes.

[0040] When the developer is replaced or the tank is cleaned, the sewage valves of the tanks are opened, and the waste liquid directly flows into the sewage tank 12 through the sewage discharge pipes for centralized storage, so as to realize the centralized collection and treatment of the waste developer liquid and meet the environmental protection requirements.

[0041] An automatic developer detection method comprises the following steps: S1, a label written with information of to-be-tested developer is pasted on a sample test tube 8 containing the corresponding to-be-tested developer, and then the sample test tube 8 is inserted into a to-be-tested sheet 7; S2, standard developer is poured into a standard developer tank 4; S3, the mechanical claw 5 clamps the to-be-tested sheet 7 and moves to above a to-be-tested developer tank 2, a liquid taking syringe 9 draws the to-be-tested developer in the sample test tube 8 by means of the moving mechanism 6 and a push-pull assembly 10, and then the to-be-tested developer is transferred to the to-be-tested developer tank 2. The mechanical claw 5 rotates and makes the detection part 702 of the to-be-tested sheet 7 face downward. The detection part 702 of the to-be-tested sheet 7 is lowered in the to-be-tested developer by means of the mechanical claw 5. S4, after the test piece 7 is soaked in the developer to be tested, the liquid taking syringe 9 and the mechanical claw 5 clamping the test piece 7 are moved to the rinsing tank 3 respectively, the liquid taking syringe 9 draws the water in the rinsing tank 3 and discharges, the residual developer in the liquid taking syringe 9 is cleaned, and then the mechanical claw 5 clamps the test piece 7 in the rinsing tank 3 to rinse and dry the detection part 702 of the test piece 7; S5, the mechanical claw 5 clamps the test piece 7 after cleaning and moves to above the standard developer tank 4, the mechanical claw 5 rotates and makes the standard part 703 of the test piece 7 face downward, and the standard part 703 of the test piece 7 is lowered and soaked in the standard developer by the mechanical claw 5; S6, after the test piece 7 is soaked in the standard developer, the mechanical claw 5 clamps the test piece 7 and moves to the rinsing tank 3 to rinse and dry the standard part 703 of the test piece 7, and then the test piece 7 is placed in the discharging area for standby; S7, the developer to be tested in the last group of developer tanks 2 is discharged, and after the developer tank 2 is cleaned, steps S3-S6 are repeated; S8, after all the developers to be tested are detected, the workers uniformly observe the test pieces 7 corresponding to the developers to be tested, and determine the quality of the developer to be tested by comparing the line clarity of the detection part 702 and the standard part 703 of the test piece 7.

[0044] In addition, in step S8, the unified comparison is carried out, the batch detection efficiency is improved, and the subjective judgment error of the workers can be reduced in a short time range.

[0045] The detection part 702 of the to-be-tested sheet 7 is immersed in the to-be-tested developer for the same time as the standard part 703 is immersed in the standard developer.

[0046] The immersion time is 60s, which ensures that the developing conditions of the detection part 702 and the standard part 703 are consistent, eliminates the influence of the immersion time difference on the developing effect, and further improves the accuracy and comparability of the detection result.
