The rapid development of artificial intelligence chips is profoundly changing the semiconductor industry. Today's high-performance CPUs and GPUs integrate billions of transistors on a single substrate and improve computational efficiency and reduce latency through advanced packaging technologies such as 2.5D and 3D stacking. However, as artificial intelligence chips become increasingly complex, the industry is calling for moving the testing phase forward to wafer testing. This transformation not only allows for earlier screening of defective chips in the manufacturing process, reducing waste, but also significantly increases overall output and brings considerable cost advantages.
Despite the many advantages of wafer testing, it faces a serious challenge: heat dissipation. AI chips generate a large amount of heat during the testing process to cope with high-performance computing loads. In wafer level testing, the density of micro bumps used for electrical detection is extremely high, with thousands of test points and a diameter of only a few micrometers. Accurate contact must be ensured to ensure the stability of data transmission. However, the large number of connections and high power density often lead to local heat concentration. If temperature cannot be effectively controlled, heat accumulation can cause distortion of test results, damage to probes, and even endanger the chip itself. Unlike the cooling solution that can be integrated through packaging during the final testing phase, wafer level testing requires a completely different heat dissipation mechanism to cope with thermal loads, and precise temperature control is crucial.
To solve this problem, intercooler has introduced a high and low temperature chuck system. This system has a wide temperature control range, compact cooling kit, pure air refrigeration, high temperature accuracy and stability control, and other characteristics. With advanced chuck heat exchangers, the temperature range of the high and low temperature chuck system is -60 ℃ to+200 ℃, and the temperature uniformity is maintained at ± 0.5 ° C. It is widely used for temperature dependent electrical performance key parameter analysis of semiconductor devices or wafers with a size of eight inches or less.
Semiconductor wafer testing: Ensure thermal stability during wafer level testing of high-power devices such as AI chips and high bandwidth memory (HBM).
Advanced Packaging: Supports thermal management requirements for advanced packaging technologies such as 2.5D/3D packaging and Chiplets.
High precision manufacturing: providing a stable temperature environment to improve processing accuracy in fields such as optical components and precision machining.
Research experiments: used in experimental scenarios that require extreme temperature control, such as materials science and quantum computing.
The high and low temperature chuck system is a key technology for solving the problem of high power density heat dissipation. Its high efficiency, precision, and reliability make it a core equipment in fields such as semiconductors and advanced manufacturing. With the rapid development of technologies such as AI, 5G, and quantum computing, the market demand for high and low temperature chuck systems will continue to grow, and technological innovation will further drive the industry towards high precision and low energy consumption.
