Description

Background Art

[0002] Burn-in testing is a non-destructive test that must be performed on all semiconductor components. It is an essential means of reliability screening and a crucial quality assurance method, eliminating defective components. Traditionally, burn-in testing requires operators to set the burn-in duration and configure different burn-in stimulus signals for each batch of products. During the burn-in process, they must constantly monitor device power and output signals. If significant deviations in device power or output signals occur, the resulting problem and the time of onset must be recorded to assess the impact of burn-in time on device performance. However, chip burn-in is a lengthy process, and operators cannot always be physically present in the burn-in chamber, constantly monitoring the oscilloscope readings. Readings and recordings are typically performed at fixed intervals, leading to misinterpretations and delays in burn-in results. Furthermore, as devices become increasingly complex and integrated, the demand for stimulus signals becomes increasingly stringent. Traditional manual inspection techniques are no longer suitable for new burn-in chambers, which require intelligent monitoring, automatic alarms, automated data recording, and automated data classification and recognition. The intelligent burn-in system is based on the traditional burn-in system and utilizes artificial intelligence technologies such as anthropomorphic control to realize system functions and enhance system intelligence. It intelligently monitors and processes power supply data, sensor data, burn-in data, and various feedback data, thereby achieving intelligent data detection for burn-in equipment.

[0003] Therefore, traditional manual inspection technology will no longer be applicable to new aging box equipment, and it is difficult to accurately realize intelligent monitoring, automatic alarm, and automatic recording of experimental data of the aging box. Summary of the Invention

[0043] The analog signal acquisition module is used to obtain the analog signals collected by each sensor based on each aging device, and perform analog-to-digital conversion on the analog signals to obtain a first digital signal and send it to the logic control module.

[0044] In order to more clearly illustrate the data detection system based on the aging box of the present invention, Figure 1 Each step in the embodiment of the present invention is described in detail.

[0045] The data detection system based on the aging box of the first embodiment of the present invention is described in detail as follows:

[0046] The host computer module is used to send power command signals, burn-in commands, digital frequency commands, and receive return data from the logic control module;

[0047] In this embodiment, the host computer module first sends a power-on signal to activate the system's primary power supply. Once the primary power supply's feedback signal is correct, the system's secondary power supply is activated. This secondary voltage is used to provide power to the various burn-in components. In this embodiment, the primary power supply provides primary direct input power to the baseboard, cooling system, and heating system.

[0048] In this embodiment, the aging instructions include various instruction signals such as a temperature control signal and an aging time setting signal;

[0049] The logic control module is used to receive the power command signal and the aging command sent by the host computer module, and parse the aging command and send it to each aging device; at the same time, it receives the feedback signal generated by each aging device, filters the feedback signal of each single cycle of each aging device to obtain a first filtered signal; it also receives the first digital signal sent by the analog signal acquisition module, and then filters the first digital signal to obtain a second filtered signal and temporarily stores it in the data temporary storage module; then compares the filtered signals of the same signal type to generate a comparison difference, and stores the corresponding filtered signals of the comparison difference that meets the conditions in the data storage module; and also generates feedback data based on the comparison difference and sends it to the host computer module;

[0050] In this embodiment, the logic control module further compares multi-cycle filtered signals of the same signal type to generate a comparison difference, and stores the filtered signals corresponding to the comparison difference that meets the conditions in the data storage module; and further generates return data based on the comparison difference and sends it to the host computer module, specifically including:

[0051] During the burn-in process, the host computer module sends burn-in device information, and the drive logic control module sends different burn-in vectors for different burn-in devices, and sends burn-in duration and burn-in temperature dynamic instruction information.

[0052] like Figure 2 As shown, the logic control module stores the i-th period filtered signal of the i-th cycle of the same signal type in the data temporary storage module, and after receiving the i+1-th period filtered signal of the i+1-th cycle, compares the i-th period filtered signal with the i-th period filtered signal to obtain a first comparison difference; if the first comparison difference is within the set threshold a, it is considered that the difference between the two data is caused by a system error, and then collects the next cycle data. If the cycle data is compared with the previous two data respectively to obtain two relative comparison differences, if the two relative comparison differences are both within the threshold a, it is considered that the data comparison result is correct, and then the received signal is stored in the data storage module; if the first comparison difference is within the set threshold a, it is considered that the difference between the two data is caused by a system error, and then collects the next cycle data. If the cycle data is compared with the previous two data respectively to obtain two relative comparison differences, and if the two relative comparison differences are both within the threshold a, it is considered that the data comparison result is correct, and then the received signal is stored in the data storage module; If the value is not within the set threshold a, wait for the filtered signal of the i+3th period and the filtered signal of the i+4th period, and compare the filtered signal of the i+3th period to obtain a second comparison difference. If the second comparison difference is not within the threshold a, it is considered that the numerical deviation is serious, and the filtered signal is immediately uploaded to the host computer module and an alarm is issued; if the second comparison difference is within the threshold a, the filtered signal with the largest deviation value and the smallest deviation value in the filtered signals from the i+1th period to the i+4th period and the time nodes corresponding to the filtered signals are sent to the host computer module; and the filtered signals other than the filtered signals with the largest deviation value and the smallest deviation value are saved to the data storage module for long-term storage.

[0053] Specifically, regarding threshold a, the setting of threshold a is designed based on the required accuracy of the device. The specific value of threshold a is set by the operator on the host computer to improve the system's accuracy. The smaller the threshold setting, the higher the system accuracy. In this embodiment, the returned data is the average or extreme value of each comparison difference. Based on the host computer settings, the obtained average or extreme value and the corresponding data are returned and sent to the host computer module.

[0054] A digital signal sending module, configured to receive a digital frequency instruction from a host computer module and generate a second digital signal based on the digital frequency instruction, and transmit the second digital signal to each burn-in device. Each burn-in device performs internal gate circuit actions based on the second digital signal and generates a feedback signal.

[0055] In this embodiment, the digital signal sending module specifically sends digital signals of different frequency ranges for different aging devices, and switches the second digital signal of different amplitude and frequency based on the digital frequency instruction, which can meet the different aging states of the device such as static aging and dynamic aging, and the amplitude can be switched to fixed-frequency digital signals of different amplitudes and frequencies by modifying the host computer instruction.

[0062] In this embodiment, a specific verification algorithm is added to the communication code to ensure high reliability communication between the host computer and the burn-in board.

[0063] The signal self-check module is used to perform self-checks on various signals and instructions. It is in the first task processing echelon for self-checking instructions and signals issued by the host computer module. After completing self-checks on each instruction and signal from the host computer module, it then performs signal self-checks on all modules in the data intelligent detection system other than the host computer module. This self-check includes checking for data accuracy, module response accuracy, and feedback signal accuracy. If a signal fails self-check, a log is immediately generated and an alarm is issued. In this embodiment, the signal self-check module uses a specific algorithm to perform self-checks on each instruction and signal.
