[0051] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0052] The chip three-temperature testing method provided by the embodiment of the present disclosure is applied to a chip three-temperature testing device, which may be a terminal device.

[0053] In view of the problems existing in the prior art, an embodiment of the present disclosure provides a chip temperature detection method, which is applied to a test machine of a chip temperature detection system. Figure 1 is a flow chart of a chip temperature detection method provided by an embodiment of the present disclosure. Figure 2 This is a schematic diagram of the interaction between a sorting machine and a testing machine provided by the embodiment of the present disclosure, combined with Figure 1 and Figure 2 ,The specific process of the chip temperature detection method includes:

[0054] S110 , the testing machine outputs a target control signal to the sorting machine in response to receiving a target selection operation triggered by a target object, so that the sorting machine controls the temperature of the sorting machine cavity to rise to a preset temperature after receiving the target control signal.

[0055] The target selection operation is used to select a test mode for the chip to be tested. The test modes for the chip to be tested include low temperature test, normal temperature test, and high temperature test.

[0056] Among them, the target selection operation is used to select the test mode of the chip to be tested. The test modes of the chip to be tested include low-temperature testing, normal temperature testing and high-temperature testing. For example, the test environment temperature of the chip to be tested is -40 degrees Celsius during low-temperature testing, the test environment temperature of the chip to be tested is 25 degrees Celsius during normal temperature testing, and the test environment temperature of the chip to be tested is 125 degrees Celsius during high-temperature testing.

[0057] Specifically, the chip temperature detection system includes a testing machine and a sorting machine. The sorting machine includes a high and low temperature hot and cold hedge meter, a temperature sensor, a sorting machine cavity, a carrier and a test board. The carrier carries the test board. The sorting machine cavity and the carrier form a closed space. The chip to be tested is communicatively connected with the test board. The test board and the chip to be tested are arranged in the closed space. The temperature sensor collects the temperature of the sorting machine cavity.

[0058] The target objects may be chip design engineers of a chip design company, and the selection operations include a low-temperature test selection operation, a normal-temperature test selection operation, and a high-temperature test selection operation.

[0059] In a specific embodiment, in response to a target selection operation triggered by a received target object, a target control signal is output to the sorting machine, so that the sorting machine controls the temperature of the sorting machine cavity to rise to a preset temperature after receiving the target control signal.

[0060] Specifically, when the testing machine receives the target selection operation triggered by the target object, it outputs a target control signal to the sorting machine to control the high and low temperature hot and cold hedger of the sorting machine, so as to raise the temperature in the sorting machine cavity to the target test temperature corresponding to the test mode based on the high and low temperature hot and cold hedger. For example, if the test mode selected by the target object is low temperature test, the high and low temperature hot and cold hedger of the sorting machine will control the temperature in the sorting machine cavity to -40 degrees Celsius; if the test mode selected by the target object is normal temperature test, the high and low temperature hot and cold hedger of the sorting machine will control the temperature in the sorting machine cavity to 25 degrees Celsius; if the test mode selected by the target object is high temperature test, the high and low temperature hot and cold hedger of the sorting machine will control the temperature in the sorting machine cavity to 125 degrees Celsius.

[0061] In some usage scenarios that require high chip precision, it is necessary to ensure the accuracy of the chip parameters collected by the chip in the corresponding low-temperature test, normal temperature test, and high-temperature test scenarios. In order to ensure the accuracy of the chip parameters collected by the chip in the corresponding test mode, it is necessary to ensure that the temperature of the chip reaches the set temperature under the low-temperature test, normal temperature test, and high temperature test. However, in the existing technology, during the chip testing process, only the temperature of the sorting machine cavity where the chip is located reaches the temperature of the low-temperature test, normal temperature test, and high temperature test, and it cannot be guaranteed that the temperature of the chip reaches the temperature of the low-temperature test, normal temperature test, and high temperature test. Therefore, in the existing chip testing process, the accuracy of the chip parameters collected by the chip under the three-temperature test cannot be guaranteed.

[0062] Based on the problems existing in the prior art, in the chip temperature detection method provided in the embodiment of the present disclosure, the preferred test machine outputs a target control signal to the sorting machine based on the target selection operation triggered by the target object, so that the sorting machine controls the sorting machine cavity to rise to a preset temperature after receiving the target control signal.

[0063] S120: The tester obtains voltage information of the chip to be tested in the sorter, and determines the actual temperature of the chip to be tested in the sorter based on the voltage information.

[0064] In addition, the tester is not only connected to the sorter for communication, but also connected to the chip to be tested through the test board on which the chip to be tested is placed.

[0065] In a specific embodiment, the tester obtains the voltage information of the chip to be tested in the sorting machine, and determines the actual temperature of the chip to be tested in the sorting machine based on the voltage information, including: the tester collects the sampling voltage of the chip to be tested inside the sorting machine at a sampling moment; the tester determines the actual temperature of the chip to be tested in the sorting machine at the sampling moment based on the sampling voltage, the reference temperature and the reference voltage.

[0066] The tester obtains the sampling voltage of the chip to be tested in the sorter at different sampling times by placing the test board on which the chip to be tested is placed, and then determines the actual temperature of the chip to be tested in the sorter at the sampling time based on the sampling voltage, reference temperature and reference voltage.

[0067] Specifically, the actual temperature of the chips to be tested in the sorter satisfies:

[0068] T=TReference+(V-VReference)*α

[0069] Wherein, T is the actual temperature of the chip to be tested in the sorter, V is the sampling voltage of the chip to be tested in the sorter, TReference is the reference temperature, VReference is the reference voltage, and α is the temperature voltage coefficient.

[0070] The temperature voltage coefficient is a preset value. The reference voltage under low temperature test is based on the low temperature test scenario (for example, -40 degrees Celsius, that is, the reference temperature under low temperature test is -40 degrees Celsius), given a fixed current, and the voltages of N test chips under the fixed current are collected separately, and the average is obtained; the reference voltage under normal temperature test is based on the normal temperature test scenario (for example, 25 degrees Celsius, that is, the reference temperature under normal temperature test is 25 degrees Celsius), given a fixed current, and the voltages of N test chips under the fixed current are collected separately, and the average is obtained; the reference voltage under high temperature test is based on the high temperature test scenario (for example, 125 degrees Celsius, that is, the reference temperature under high temperature test is 125 degrees Celsius), given a fixed current, and the voltages of N test chips under the fixed current are collected separately, and the average is obtained.

[0071] S130 , the tester determines a target adjustment signal according to a relationship between the actual temperature of the chip to be tested in the sorter and the preset temperature of the sorter cavity.

[0072] In a specific embodiment, the tester determines the target adjustment signal according to the relationship between the actual temperature of the chip to be tested in the sorter and the preset temperature of the sorter cavity, including:

[0073] When the actual temperature of the chip to be tested in the sorting machine is lower than the preset temperature of the sorting machine cavity, the first target adjustment signal is determined according to the difference information between the preset temperature of the sorting machine cavity and the actual temperature of the chip to be tested in the sorting machine; when the actual temperature of the chip to be tested in the sorting machine is higher than the preset temperature of the sorting machine cavity, the second target adjustment signal is determined according to the difference information between the actual temperature of the chip to be tested in the sorting machine and the preset temperature of the sorting machine cavity.

[0074] In a specific implementation method, when the actual temperature of the chip to be tested in the sorting machine is lower than the preset temperature of the sorting machine cavity, a first target adjustment signal is output; when the actual temperature of the chip to be tested in the sorting machine is higher than the preset temperature of the sorting machine cavity, a second target adjustment signal is output. The specific sizes of the output first target adjustment signal and the second target adjustment signal that need to be adjusted are based on the relationship between the actual temperature of the chip to be tested in the sorting machine and the preset temperature of the sorting machine cavity.

[0075] Therefore, before executing step S130, it also includes: the tester obtains the temperature adjustment value of the sorting machine cavity under different temperature differences, wherein the temperature difference is the absolute value of the difference between the actual temperature of the chip to be tested in the sorting machine and the preset temperature of the sorting machine cavity.

[0076] First, the temperature adjustment value of the sorting machine cavity is obtained under different temperature differences, and then the target adjustment signal is output according to the relationship between the actual temperature of the chip to be tested in the sorting machine and the preset temperature of the sorting machine cavity. When the actual temperature of the chip to be tested in the sorting machine is lower than the preset temperature of the sorting machine cavity, the temperature adjustment value corresponding to the temperature difference is found according to the temperature difference between the preset temperature of the sorting machine cavity and the actual temperature of the chip to be tested in the sorting machine, and then the first target adjustment signal is output to the sorting machine to make the sorting machine increase the temperature of the sorting machine cavity by the temperature adjustment value. When the actual temperature of the chip to be tested in the sorting machine is higher than the preset temperature of the sorting machine cavity, the temperature adjustment value corresponding to the temperature difference is found according to the temperature difference between the actual temperature of the chip to be tested in the sorting machine and the preset temperature of the sorting machine cavity, and then the second target adjustment signal is output to the sorting machine to make the sorting machine lower the temperature of the sorting machine cavity by the temperature adjustment value.

[0077] S140, the testing machine outputs a target adjustment signal to the sorting machine, so that the sorting machine controls the temperature of the sorting machine cavity to be adjusted based on the preset temperature after receiving the target adjustment signal.

[0078] After determining the target adjustment signal, the tester outputs the target adjustment signal to the sorter. The sorter receives the target adjustment signal output by the tester and adjusts the temperature of the sorter cavity so that under the three-temperature test, the actual temperature of the chip to be tested in the sorter cavity meets the three-temperature test requirements, thereby improving the test accuracy of the chip to be tested.

[0079] Based on the above embodiment, the method provided in the embodiment of the present disclosure further includes:

[0080] When the actual temperature of the chip to be tested is the same as the preset temperature of the sorting machine cavity, the tester outputs a test signal to the sorting machine to enable the sorting machine to test the chip to be tested and sends the obtained test parameters of the chip to be tested to the tester.

[0081] In the above embodiment, after the test machine outputs the target adjustment signal to the sorting machine, the sorting machine will adjust the temperature of the sorting machine cavity. After the temperature of the sorting machine cavity is adjusted, the sampling voltage of the chip to be tested will change, and the test machine will obtain the sampling voltage of the chip to be tested in the sorting machine cavity again, and then determine the actual temperature of the chip to be tested in the sorting machine according to the sampling voltage, reference temperature and reference voltage of the chip to be tested. When the actual temperature of the chip to be tested is the same as the preset temperature of the sorting machine cavity, the test machine outputs a test signal to the sorting machine to make the sorting machine test the chip to be tested, and receives the sample voltage. The test machine collects the test parameters of the chip to be tested collected by the sorting machine. After receiving the test parameters of the chip to be tested collected by the sorting machine, the test machine determines whether the chip to be tested meets the design requirements by comparing the test parameters of the chip to be tested with the preset parameters. When the chip to be tested meets the design requirements, the test machine outputs an indication signal to instruct the sorting machine to flow the chip to be tested into the normal workpiece area. When the chip to be tested does not meet the design requirements, the test machine outputs an indication signal to instruct the sorting machine to flow the chip to be tested into the abnormal workpiece area, thereby realizing accurate wafer testing of each chip to be tested under different test modes.

[0082] The chip temperature detection method provided by the embodiment of the present disclosure is as follows: first, the tester responds to the target selection operation triggered by the target object and outputs a target control signal to the sorter, so that the sorter controls the temperature of the sorter cavity to rise to a preset temperature after receiving the target control signal; then the tester obtains the voltage information of the chip to be tested in the sorter, and determines the actual temperature of the chip to be tested in the sorter based on the voltage information; then the tester determines the target adjustment signal based on the relationship between the actual temperature of the chip to be tested in the sorter and the preset temperature of the sorter cavity; finally, the tester outputs the target adjustment signal to the sorter, so that the sorter controls the temperature of the sorter cavity to be adjusted based on the preset temperature after receiving the target adjustment signal. By collecting the relationship between the actual temperature of the chip to be tested during the test process and the preset temperature of the sorter cavity, the temperature of the sorter cavity is adjusted, thereby ensuring that the temperature of the chip to be tested reaches the temperature in the test mode selected by the target object, and ensuring the accuracy of the chip parameters collected under the three-temperature test.

[0083] Based on the above embodiments, Figure 3This is a flow chart of another chip temperature detection method provided by an embodiment of the present disclosure. The chip temperature detection method is applied to a sorting machine of a chip temperature detection system, combined with Figure 2 、 Figure 3 ,The specific process of the chip temperature detection method includes:

[0084] S210 , the sorting machine receives the target control signal output by the testing machine, and controls the temperature of the sorting machine cavity to rise to a preset temperature according to the target control signal.

[0085] Among them, different target control signals correspond to different preset temperatures.

[0086] Specifically, after the sorting machine receives the target control signal output by the testing machine, the sorting machine controls the high and low temperature hot and cold hedge instrument based on the target control signal output by the testing machine, so as to raise the temperature in the sorting machine cavity to the target test temperature corresponding to the test mode based on the high and low temperature hot and cold hedge instrument. For example, if the test mode selected by the target object is low temperature test, the high and low temperature hot and cold hedge instrument of the sorting machine controls the temperature in the sorting machine cavity to -40 degrees Celsius; if the test mode selected by the target object is normal temperature test, the high and low temperature hot and cold hedge instrument of the sorting machine controls the temperature in the sorting machine cavity to 25 degrees Celsius; if the test mode selected by the target object is high temperature test, the high and low temperature hot and cold hedge instrument of the sorting machine controls the temperature in the sorting machine cavity to 125 degrees Celsius.

[0087] S220: The sorting machine receives the target adjustment signal output by the testing machine, and adjusts the temperature of the sorting machine cavity according to the target adjustment signal.

[0088] When the sorter receives the target adjustment signal output by the tester, it adjusts the temperature of the sorter cavity so that under the three-temperature test, the actual temperature of the chip to be tested in the sorter cavity meets the three-temperature test requirements, thereby improving the test accuracy of the chip to be tested.

[0089] It should be noted that the chip temperature detection method provided in the above embodiment is applied to the chip mass production test process.
