Description

Technical Field

[0001] The present application relates to the field of semiconductor technology, and in particular to a capillary reliability test method, device, electronic equipment and storage medium. Background Art

[0002] With the continuous development of semiconductor cryogenic refrigeration equipment, the reliability of components in semiconductor cryogenic refrigeration equipment has become one of the key factors affecting the life and accuracy of the equipment. Among them, the capillary, as one of the important components in semiconductor cryogenic refrigeration equipment, faces severe tests of external loads. The traditional method of capillary reliability verification mainly adopts the static test method, which mainly evaluates the performance of the capillary under static load. However, in actual applications, the capillary in the semiconductor cryogenic refrigeration equipment will not only be subjected to static forces, but also to fatigue loads due to factors such as frequent start and stop of the equipment and vibration during operation. Fatigue loads may cause fatigue damage to the capillary, such as the generation and expansion of microcracks, which in turn affects its structural reliability and service life. However, the static test method cannot accurately reflect the true performance of the capillary under fatigue load. Therefore, relying solely on the static test method to verify the reliability of the capillary may underestimate its risks in actual use and fail to fully ensure the safe and stable operation of the semiconductor cryogenic refrigeration equipment.

According to the change of the capillary stress amplitude, the specific time of the capillary failure can be identified, thereby improving the accuracy of the test.

[0056] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments.

Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0057] Considering that the static test method cannot accurately reflect the actual performance of the capillary under fatigue load, relying solely on the static test method to verify the reliability of the capillary may underestimate its risk in actual use and fail to fully ensure the safe and stable operation of semiconductor cryogenic refrigeration equipment. Based on this, the embodiments of the present application provide a capillary reliability test method, device, electronic device and storage medium to improve the accuracy of the capillary reliability test and shorten the test time, which is described below through embodiments.

[0058] To facilitate understanding of this embodiment, a capillary reliability test method disclosed in the embodiment of the present application is first introduced in detail. The capillary is a component in a semiconductor cryogenic refrigeration device. The method includes: a preparation stage and a test stage; Figure 1 As shown, the preparation stage includes the following steps S101-S103:

[0059] S101: creating a three-dimensional simulation model of a capillary to be tested;

[0060] S102: performing simulation analysis on the three-dimensional simulation model to determine the size and position of the static load applied to the capillary during the test phase, the test loading frequency of the capillary, and the load level spectrum; wherein the test loading frequency is the rate at which the vibration load applied to the capillary changes over time during the test phase; the load level spectrum includes the frequency of occurrence of the total load of each level after the total load is divided into different levels according to the size; the total load is the sum of the static load and the vibration load received by the capillary during the test phase;

[0061] S103: determining the mass of an additional mass block to be disposed on the capillary tube during the test phase according to the magnitude of the static load;

[0062] The test phase includes the following steps S104-S106:

[0063] S104: configuring an additional mass block on the capillary according to the position of the static load, so as to apply the static load to the capillary through the additional mass block, and after installing the strain gauge on the capillary and installing the capillary on the vibration table, inputting the test loading frequency and the load level spectrum into the vibration table, so that the vibration table operates according to the test loading frequency and the load level spectrum, so as to apply the vibration load to the capillary through the operating vibration table;

[0064] S105: in a process of applying a static load to the capillary by means of an additional mass block and applying a vibration load to the capillary by means of a running vibration table, monitoring a stress amplitude of the capillary by means of a strain gauge;

[0065] S106: Determine the reliability of the capillary according to the stress amplitude of the capillary.

[0066] In step S101, Figure 2 As shown, a schematic diagram of a capillary is shown. In this embodiment, the capillary to be tested may be one or more. When there are more than one capillary to be tested, the manufacturing processes of different capillaries to be tested are different, but the structural information is the same.

[0067] In a possible implementation, when creating a three-dimensional simulation model of a capillary to be tested, the specific steps are: inputting the mathematical model of the capillary to be tested into model simulation software, and creating a three-dimensional simulation model of the capillary through the model simulation software; wherein the mathematical model contains structural information of the capillary.

[0068] In this embodiment, since the three-dimensional simulation model of the capillary is created based on the structural information of the capillary, and the structural information of different capillaries to be tested is the same, all capillaries correspond to the same three-dimensional simulation model. Figure 3 , which shows a schematic diagram of a three-dimensional simulation model of a capillary.

[0069] In step S102, a static simulation analysis is performed on the three-dimensional simulation model to determine the size and position of the static load applied to the capillary during the test phase, wherein the static load applied to the capillary can be understood as the force applied to the capillary.

[0070] Modal analysis is performed on the three-dimensional simulation model to determine the test loading frequency of the capillary. The test loading frequency is the rate at which the vibration load applied to the capillary changes over time during the test phase. The vibration load is provided by a vibration table, on which the capillary is placed, and the vibration table provides the capillary with a vibration load through vibration.

[0071] Fatigue simulation analysis is performed on the three-dimensional simulation model to determine the load level spectrum. The load level spectrum includes the frequency of occurrence of the total load at each level after the total load is divided into different levels according to size; the total load is the sum of the static load and the vibration load that the capillary tube is subjected to during the test phase.

[0072] In this embodiment, for each level of total load, the frequency of occurrence of the level of total load refers to how many frequencies of vibration loads are required to make the capillary fail (i.e., damaged) if the level of total load is applied to the capillary. Usually, the level of total load is negatively correlated with its corresponding frequency. Specifically, the larger the level of total load (i.e., the larger the force applied to the capillary), the smaller the corresponding frequency (i.e., the less frequency the force needs to be applied to the capillary). In other words, when the level of total load is large enough, only a small frequency is required to make the capillary fail; conversely, the smaller the level of total load (i.e., the smaller the force applied to the capillary), the more corresponding frequencies (i.e., the less frequency the force needs to be applied to the capillary). In other words, when the level of total load is small enough, only a small frequency is required to make the capillary fail.

[0073] Exemplarily, assume that the load level spectrum includes three levels of total loads, namely low-level total load, intermediate total load, and high-level total load. Among them, the frequency of occurrence of the low-level total load is assumed to be 500 times, then the frequency of occurrence of the intermediate total load is usually less than 500 times, for example, 400 times, and the frequency of occurrence of the high-level total load will be less than 400 times, for example, 300 times.

[0074] In step S103 , the magnitude of the static load is divided by the gravitational acceleration to obtain the mass of the additional mass block configured on the capillary during the test phase.

[0075] In step S104, an additional mass block is selected for the capillary from the plurality of mass blocks according to the mass of the additional mass block configured on the capillary during the test phase determined in step S103. The mass of the selected additional mass block is the same as the mass calculated in step S103.

[0076] Then, according to the position of the static load applied to the capillary during the test phase determined in step S102, the selected additional mass block is configured (for example, glued) to the corresponding position of each capillary (that is, the position of the static load determined in step S102), and the strain gauge is installed (for example, glued) to the root of each capillary. It can be seen that a strain gauge and an additional mass block are installed on each capillary. Figure 4 The capillary root position is shown, as Figure 4 As shown, the root of the capillary is located near the weld.

[0077] In this embodiment, after configuring the corresponding additional mass blocks on each capillary according to the position of the static load of each capillary and installing a strain gauge on each capillary, each capillary is installed on a vibration table respectively, that is, a plurality of capillaries with different manufacturing processes are installed on the vibration table at the same time.

[0078] The test loading frequency and load level spectrum are input into the vibration table, and the vibration table vibrates based on the test loading frequency and load level spectrum. The running vibration table can apply a vibration load to each capillary. And because each capillary is equipped with an additional mass block, a static load can be applied to each capillary through the additional mass blocks respectively configured on each capillary. It can be seen that in this embodiment, each capillary on the vibration table is subjected to a static load and a vibration load, and each capillary is subjected to the same vibration load and the same static load.

[0079] In a possible implementation, when executing step S104 to make the vibration table operate according to the test loading frequency and load level spectrum so as to apply a vibration load to the capillary through the operating vibration table, the following steps may be specifically performed:

[0080] S1041: according to the load level spectrum, assigning corresponding application frequencies to each level of total load in the load level spectrum;

[0081] S1042: The vibration table is operated in the order of the total load of the levels from small to large based on the test loading frequency and the application frequency corresponding to each total load of each level, so as to apply a vibration load to the capillary through the running vibration table.

[0082] Exemplarily, it is assumed that the load level spectrum includes three levels of total load and the frequencies corresponding to each level of total load. The three levels of total load are low-level total load, medium-level total load, and high-level total load. The frequency of occurrence of the low-level total load is assumed to be the first frequency, the frequency of occurrence of the medium-level total load is the second frequency, and the frequency of occurrence of the high-level total load is the third frequency.

[0083] At this time, if a low-level total load is applied to the capillary, a vibration load of the first frequency is required to make the capillary fail (i.e., damaged). If a medium-level total load is applied to the capillary, a vibration load of the second frequency is required to make the capillary fail. If a high-level total load is applied to the capillary, a vibration load of the third frequency is required to make the capillary fail.

[0084] Among them, the first frequency is greater than the second frequency, which is greater than the third frequency. The high-level total load is greater than the middle-level total load, which is greater than the low-level total load.

[0085] In step S1041, illustratively, a first application frequency is allocated to the low-level total load, and the first application frequency is less than the first frequency. A second application frequency is allocated to the intermediate total load, and the second application frequency is less than the second frequency. A third application frequency is allocated to the high-level total load, and the third application frequency is less than the third frequency. In this embodiment, the principle of allocating corresponding application frequencies to the low-level total load, the intermediate total load, and the high-level total load is: first apply the low-level total load to the capillary according to the first application frequency, then apply the intermediate total load to the capillary according to the second application frequency, and finally apply the high-level total load to the capillary according to the third application frequency, so as to ensure that the cumulative damage caused to the capillary is stronger than the cumulative damage required for the capillary to fail.

[0086] In step S1042, illustratively, the vibration table is operated in the order of low-level total load, intermediate total load, and high-level total load based on the test loading frequency and the first application frequency, second application frequency, and third application frequency corresponding to the low-level total load, the intermediate total load, and the high-level total load, respectively, so as to apply vibration loads to all capillaries on the vibration table through the running vibration table.

[0087] In step S105 , while the vibration table operates based on the test loading frequency and load level spectrum to apply vibration load and static load on each capillary, the stress amplitude of each capillary is monitored by a strain gauge on each capillary.

[0088] In step S106, the reliability of each capillary is determined based on the stress amplitude of each capillary. Specifically, in this embodiment, it is considered that the specific failure time of the capillary cannot be observed by manual visual inspection. In fact, before the capillary breaks, it has failed for a period of time. In order to more accurately record the time when the capillary fails, in this embodiment, the stress amplitude of the capillary is monitored by a strain gauge. When the capillary is about to fail, its stress amplitude will drop sharply. According to the change of stress amplitude, the specific time of capillary failure can be identified, thereby improving the accuracy of the experimental test. Based on this, in this embodiment, when executing step S106, it can be specifically performed according to the following steps:

[0089] S1061: determining the failure time of the capillary according to the change of the stress amplitude of the capillary; wherein, when the capillary fails, the stress amplitude of the capillary will drop suddenly;

[0090] S1062: Determine the reliability of the capillary according to the failure time of the capillary; wherein, the earlier the capillary fails, the worse the reliability of the capillary; and the later the capillary fails, the stronger the reliability of the capillary.
