Description

Technical Field

[0001] This invention relates to the field of semiconductor integrated circuit technology, and specifically to a chip test recipe management method, system, storage medium, and device. Background Technology

[0002] A recipe (process method) refers to the process flow in industrial automated manufacturing. A recipe can include the following information: multiple steps in the material processing, the values ​​of various process parameters in each step, and the termination conditions of each step, etc.

[0003] As the LED product market and manufacturing volume gradually increase, chip testing is an essential process. Chip testing machines need to be calibrated daily for different product recipes, and production can only begin after the calibration is confirmed to be error-free.

[0004] However, with the increasing market growth and product models, the number of program recipe files running on the machine is too large. Therefore, the number of recipes that need to be calibrated is also increasing. Each model's recipe needs to be calibrated daily, which leads to frequent calibration of the chip tester, easily causing calibration errors, resulting in abnormal calibrated recipes, abnormal test data of LED products, and affecting the yield of LED products. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of this invention is to provide a chip test recipe management method, system, storage medium and device, which aims to solve the technical problems of excessive number of program recipe files, long correction time, low efficiency and easy error in the prior art.

[0009] Based on the electrical parameters and the optical parameters, different recipes for LED chips of the same category are correlated to obtain the correlation coefficients of different recipes and the baseline data of different recipes.

[0010] The LED correction chip is tested according to the corresponding recipe to obtain the test data of the LED correction chip;

[0011] Based on the difference between the test data and the baseline data of the corresponding recipe, the corresponding recipe is corrected;

The calculation of the correlation coefficients effectively links different recipes, and the correlation of one recipe can be used to regulate other recipes, greatly reducing the workload of manual calibration; the LED calibration chips are tested according to the corresponding recipes to obtain the test count of the LED calibration chips. According to the method, based on the difference between the test data and the baseline data of the corresponding recipe, the corresponding recipe is corrected, which can effectively improve the accuracy of recipe testing. Based on the difference and the correlation coefficient of different recipes in the same category, the compensation coefficient of different recipes is obtained to correct and compensate other recipes in the same category, thereby obtaining different recipe corrections for LED chips of the same category.

[0019] The data from different recipe sets is filtered to remove outliers, and then the data is analyzed and compared to obtain the correlation coefficient between each recipe and other recipes.

[0020] The baseline data for each recipe is obtained by averaging the different sets of recipes.

[0021] According to one aspect of the above technical solution, the step of correcting the corresponding recipe based on the difference between the test data and the baseline data of the corresponding recipe specifically includes:

[0046] Example 1

[0047] Please see Figure 1 The image shows a chip test recipe management method provided in the first embodiment of the present invention, the method comprising steps S10-S15:

[0048] Step S10: Based on the electrical and optical parameters of the LED chip test, create several recipes of different models and sizes on the chip testing machine;

[0049] Specifically, the chip tester needs to calibrate the packaged components to the correct position when establishing the recipe; the packaged calibration refers to sending the chip to the tester to test its electrical and optical parameters after packaging, and calibrating the packaged data onto the chip tester platform to achieve the correct position.

[0050] The electrical parameters include the forward voltage parameters at different coordinates on the LED chip, and the optical parameters include the light output parameters and wavelength parameters at different coordinates on the LED chip.

[0051] Step S11: Preprocess all LED chips to classify them.

[0052] Specifically, this involves obtaining the model and size of all LED chips;

[0053] LED chips of similar models and sizes are grouped into the same category.

[0054] Examples, not limitations, can be categorized by model, such as red LED chips, red-yellow LED chips, blue-green LED chips, etc., or by size, such as red LED chips, red Mini LED chips, red Micro LED chips, etc.

[0055] It should be noted that classifying LED chips by model and size means that within the same category, the electrical and optical parameters are not significantly different, and the magnitude of their increase or decrease is similar. This allows for effective control of other recipes by leveraging the correlation of one recipe, thereby reducing the workload of operators and minimizing the error rate caused by manually adjusting different recipes one by one.

[0056] Step S12: Based on the electrical parameters and the optical parameters, associate different recipes of LED chips of the same category to obtain the association coefficients of different recipes and the baseline data of different recipes.

[0057] Specifically, within the same category of LED chips, the electrical and optical parameters of several LED chips with different recipes are obtained to obtain a set of recipes with different recipes;

[0058] The data from different recipe sets is filtered to remove outliers, and then the data is analyzed and compared to obtain the correlation coefficient between each recipe and other recipes.

[0059] It should be noted that the calculation of correlation coefficients can effectively link different recipes together, and the correlation of one recipe can be used to regulate other recipes, greatly reducing the workload of manual correction.

[0060] The baseline data for each recipe is obtained by averaging the different sets of recipes.

[0061] Step S13: Perform the corresponding recipe test on the LED correction chip to obtain the test data of the LED correction chip;

[0062] Step S14: Based on the difference between the test data and the baseline data of the corresponding recipe, the corresponding recipe is corrected;

[0063] Specifically, the test is compared with the baseline data of the corresponding recipe to obtain a difference coefficient, and the corresponding recipe is corrected based on the difference coefficient.

[0064] By comparing the data with benchmark data to obtain the difference coefficient, and then correcting the corresponding recipe based on the difference coefficient, the accuracy of recipe testing can be effectively improved.

[0065] Step S15: Based on the differences and the correlation coefficients of different recipes in the same category, compensation coefficients for different recipes are obtained to correct and compensate other recipes in the same category, thereby obtaining different recipe corrections for LED chips of the same category.

[0066] Specifically, the difference coefficient and the correlation coefficient between the corresponding recipe and other recipes are multiplied to obtain the compensation coefficient for different recipes;

[0067] Based on the compensation coefficient, different recipes are corrected and compensated to obtain different recipe corrections for LED chips of the same category.

[0068] It should be noted that by adjusting other recipes based on the difference value of one recipe and its correlation coefficient with other recipes, the accuracy of other recipe calibration can be effectively improved, the calibration workload can be reduced, calibration errors can be reduced, and the yield of LED products can be improved.

[0069] Compared with existing technologies, the chip test recipe management method in this embodiment has the following advantages: The chip test recipe management method provided by this invention can effectively shorten calibration time and reduce error rate. Specifically, based on the electrical and optical parameters of the LED chip test, several recipes of different models and sizes are established on the chip testing machine; all LED chips are preprocessed to classify them; based on the electrical and optical parameters, different recipes for LED chips of the same category are associated to obtain the correlation coefficients and baseline data of different recipes. The calculation of the correlation coefficients effectively links different recipes, and the correlation of one recipe controls other recipes, greatly reducing the workload of manual calibration; the LED calibration chip is tested according to the corresponding recipe to obtain the LED... The test data of the D-calibration chip; based on the difference between the test data and the baseline data of the corresponding recipe, the corresponding recipe is corrected, which can effectively improve the accuracy of recipe testing; based on the difference and the correlation coefficient of different recipes of the same category, the compensation coefficient of different recipes is obtained to correct and compensate other recipes of the same category, thereby obtaining different recipe calibrations for LED chips of the same category. According to the difference value of one recipe and the correlation coefficient with other recipes, other recipes are adjusted, which can effectively improve the accuracy of other recipe calibration, shorten calibration time, improve calibration efficiency, reduce calibration workload, reduce calibration errors, and improve the yield of LED products. This solves the technical problems of too many program recipe files, long calibration time, low efficiency and easy error in the prior art.

[0070] Example 2

[0071] Please see Figure 2 The image shows a chip test recipe management system provided in the second embodiment of the present invention. The system includes:

[0072] The Recipe creation module 100 is used to create several recipes of different models and sizes on the chip testing machine based on the electrical and optical parameters of the LED chip test.

[0073] Among them, the chip tester needs to calibrate the packaged components to the correct position when establishing the recipe; the packaged calibration refers to sending the chip to the tester to test the electrical and optical parameters after packaging, and calibrating the packaged data onto the chip tester platform to achieve the correct position.

[0074] The electrical parameters include the forward voltage parameters at different coordinates on the LED chip, and the optical parameters include the light output parameters and wavelength parameters at different coordinates on the LED chip.

[0075] The chip sorting module 200 is used to preprocess all LED chips to sort them.

[0076] This involves obtaining the model and size of all LED chips, and classifying LED chips with similar models and sizes into the same category.

[0077] Recipe association module 300 is used to associate different recipes of the same type of LED chip based on the electrical parameters and the optical parameters, so as to obtain the association coefficients of different recipes and the baseline data of different recipes.

[0078] Within the same category of LED chips, obtain the electrical and optical parameters of several LED chips with different recipes to obtain a set of recipes with different recipes;

[0079] The data from different recipe sets is filtered to remove outliers, and then the data is analyzed and compared to obtain the correlation coefficient between each recipe and other recipes.

[0080] The baseline data for each recipe is obtained by averaging the different sets of recipes.

[0081] The calibration chip test module 400 is used to perform corresponding recipe tests on the LED calibration chip and obtain test data of the LED calibration chip.

[0082] Recipe correction module 500 is used to correct the corresponding recipe based on the difference between the test data and the baseline data of the corresponding recipe;

[0083] The test results are compared with the baseline data of the corresponding recipe to obtain a difference coefficient. Based on the difference coefficient, the corresponding recipe is corrected.

[0084] The Recipe Compensation Module 600 is used to obtain compensation coefficients for different recipes based on the differences and the correlation coefficients of different recipes of the same category, so as to correct and compensate other recipes of the same category, thereby obtaining different recipe corrections for LED chips of the same category.

[0085] Multiply the difference coefficient and the correlation coefficient between the corresponding recipe and other recipes to obtain the compensation coefficient for different recipes;

[0086] Based on the compensation coefficient, different recipes are corrected and compensated to obtain different recipe corrections for LED chips of the same category.

[0087] Compared with existing technologies, the chip test recipe management system in this embodiment has the following advantages: The chip test recipe management system provided by this invention can effectively shorten calibration time and reduce error rate. Specifically, it classifies all LED chips through a chip classification module; based on the electrical and optical parameters, it associates different recipes for LED chips of the same category through a recipe association module, obtaining association coefficients and baseline data for different recipes. The calculation of association coefficients effectively links different recipes, allowing the correlation of one recipe to control other recipes, greatly reducing the workload of manual calibration; and it further reduces errors through a recipe correction module. The corresponding recipe correction can effectively improve the accuracy of recipe testing. By obtaining compensation coefficients for different recipes through the recipe supplementation module, other recipes of the same category can be corrected and compensated, thereby obtaining different recipe corrections for LED chips of the same category. Based on the difference value of a recipe and its correlation coefficient with other recipes, other recipes can be adjusted, which can effectively improve the accuracy of other recipe corrections, shorten correction time, increase correction efficiency, reduce correction workload, reduce correction errors, and increase the yield of LED products. This solves the technical problems of excessive number of program recipe files, long correction time, low efficiency, and easy error in the prior art.
