[0002] In the field of chip reliability testing, traditional temperature and humidity aging testing techniques have many limitations. On the one hand, the test environment is often a uniform and static temperature and humidity field, which makes it difficult to reproduce the complex scenarios of dynamic temperature and humidity changes, mechanical stress, electromagnetic interference, and other multi-physical field couplings in actual chip applications. This results in a large deviation between the test results and the actual aging condition of the chip. On the other hand, digital twin technology mostly remains at the level of simple model simulation and has not formed a deep closed loop of digital pre-simulation, physical testing, and data feedback, making it impossible to predict the chip aging trend in advance. In addition, the energy supply mostly adopts a constant voltage or current mode, which does not match the dynamic fluctuation of power consumption, energy recovery, and limited conditions during actual chip operation, and lacks full life cycle data traceability capabilities.
[0003] Therefore, it is necessary to propose a chip temperature and humidity aging test system to solve the above problems. Summary of the Invention

The core control and digital twin fusion module is used to construct a cross-scale digital twin model and map process deviations. Through dynamic scene generation and data and material feedback, it realizes closed-loop collaborative testing. The three-dimensional temperature and humidity field active construction module is used to divide three layers of space for precise temperature and humidity control. Combined with vector airflow injection and flow field simulation, it constructs a three-dimensional non-uniform temperature and humidity field.

[0014] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0015] like Figure 1 As shown, the chip temperature and humidity aging test system includes a core control and digital twin fusion module, a three-dimensional temperature and humidity field active construction module, a multi-physics field coupled stress loading module, an energy self-adaptive supply module, and a full life cycle data traceability and intelligent evaluation module. The core control and digital twin fusion module is used to construct a cross-scale digital twin model and map process deviations. Through dynamic scene generation and data and physical feedback, it achieves closed-loop collaborative testing.

At the micro level, the temperature and humidity response at the transistor level inside the chip is accurately simulated; at the macro level, the thermal diffusion and moisture penetration characteristics of the entire package are reproduced to capture the multi-scale aging coupling effect from the transistor to the package. Process Deviation Mapping: Integrating process deviation-aging correlation function, it transforms process data in chip manufacturing into parameter variables of digital twin model. For example, if the lithography linewidth deviation of a certain batch of chips is ±10% of the design value, the model will assign correlation parameters of linewidth fluctuation, current density change and temperature rise in the corresponding area, making digital simulation closer to the individual aging differences of actual chips, and solving the problem of existing technology ignoring the impact of process deviation on aging. The real-time closed-loop control submodule includes a dynamic scene generation engine: based on the target application scenario of the chip, it generates sudden change, gradient, and cyclic composite temperature and humidity curves. For example, it can simulate a car accelerating rapidly, where the temperature rises from 25°C to 120°C in 10 seconds and the humidity drops from 60% to 10%; or simulate a gradual change scenario in an industrial production line where the temperature rises from 80°C to 150°C at a rate of 0.5°C / min, while the humidity slowly decreases from 95%RH to 60%RH at a rate of 2%RH / min. Unlike existing fixed temperature and humidity spectra, this engine can reproduce the dynamic stress characteristics of real-world scenarios. Digital pre-simulation - physical test feedback: When the digital twin model predicts stress concentration inside the chip and material moisture saturation, the temperature and humidity parameters of the physical test are automatically adjusted to ensure that the physical test accurately captures the key aging nodes, realizing a closed loop where digital pre-simulation guides physical testing and physical data feeds back into the digital model.
[0016] The three-dimensional temperature and humidity field active construction module is used to divide a three-layer space for precise temperature and humidity control. Combined with vector airflow injection and flow field simulation, it constructs a three-dimensional non-uniform temperature and humidity field. The three-dimensional temperature and humidity field active construction module specifically includes: The layered temperature and humidity control submodule includes dividing the test chamber into a 0-5mm near-field layer, a 5-20mm middle layer, and a far-field layer larger than 20mm.

The middle layer constructs a linear temperature and humidity gradient through a gradient heating wire array and a porous ceramic humidity buffer layer, simulating the thermal and humidity gradient transition between the chip and the external environment. The far-field layer uses a high-flow-rate heat and humidity exchanger to maintain the overall energy and humidity balance of the chamber, simulating the temperature and humidity background field of the external environment. Distributed flexible sensing feedback: Graphene-based flexible sensing nodes are deployed in each layer to collect temperature and humidity data in real time and feed it back to the core control and digital twin fusion module; The dynamic flow field driving submodule includes a vector airflow injection system: through a miniature adjustable nozzle with a diameter of 0.5mm, the airflow temperature, humidity and injection angle of each nozzle can be independently controlled to simulate complex airflow disturbances, such as crosswinds and eddies when consumer electronics are used outdoors, or the impact of directional airflow near industrial fans on the temperature and humidity environment of the chip, which is different from the simple simulation of existing unidirectional uniform airflow. Flow field simulation and optimization unit: Based on computational fluid dynamics algorithms, it simulates the airflow field, temperature field, and humidity field inside the cavity in real time.

[0018] The energy self-adaptive supply module generates a dynamic power supply waveform based on power consumption prediction, recovers test energy, and adaptively adjusts the power supply to match changes in chip power consumption and environmental stress. Specifically, the energy self-adaptive supply module includes: The dynamic power consumption simulation submodule includes real-time power consumption prediction: based on a cross-scale digital twin model, it predicts the power consumption changes of the chip under temperature and humidity, mechanical stress, and EMI coupling in real time. For example, when the chip's leakage current increases due to high temperature and its parasitic capacitance changes due to mechanical stress, the submodule calculates the chip's actual power consumption curve at this time. Dynamic power supply waveform generation: Based on the predicted power consumption, a dynamic power supply waveform consistent with the actual power consumption is generated, including voltage fluctuations and current spikes, to simulate the dynamic fluctuations of the power supply in actual applications. The energy recovery and adaptive regulation submodule includes micro energy recovery: through thermoelectric conversion and electromagnetic radiation recovery, the energy generated during chip aging tests is converted into electrical energy and stored in a supercapacitor; Energy self-feedback regulation: Based on the amount of energy recovered and the dynamic power consumption requirements of the chip, the voltage, current and waveform of the external power supply are automatically adjusted to realize the dynamic cycle of sufficient energy, limited energy and energy recovery and reuse, and to reproduce chip aging under actual power supply instability or energy recovery scenarios.

For example, it is found that due to the deviation of the photolithography linewidth, the leakage current of a certain batch of chips rises 30% faster than that of other batches under a specific temperature and humidity cycle, thus clarifying the influence of the process on aging. The intelligent aging assessment and prediction submodule includes causal and transfer learning algorithms: first, causal reasoning is used to determine the causal chain of process parameters, stress response, and performance degradation, and then transfer learning is used to transfer laboratory aging data to actual application scenarios to improve prediction accuracy.
