Beijing Jiaotong University undergraduates explore Tektronix's advanced semiconductor open laboratory and experience the charm of cutting-edge high technology

November 25, 2024, Beijing, China - On October 24, senior undergraduate students of the "Power Electronics Major Comprehensive Design and Practice" of the School of Electrical Engineering of Beijing Jiaotong University, led by Professor Yang Xiaofeng, walked into the Tektronix Advanced Semiconductor Open Laboratory and started a journey of technological exploration . The purpose of this activity is to allow students to jump out of the textbooks, feel the pulse of the industry up close, and experience the charm of combining industry and education.

In the laboratory, Tektronix engineers led the students to get close to the dynamic and static characteristic parameter test equipment of new power devices such as SiC (silicon carbide) and GaN (gallium nitride), and also shared the reliability test solutions in the industry. The engineers also explained the structure, working principle and operation method of the static parameter test system in detail to the students. These tests are the basic skills of power device testing. The main content of this practical class involves the DC parameters of the device, such as breakdown voltage, leakage current, threshold voltage, and parasitic capacitance under high bias voltage. Tektronix engineers demonstrated on site how to use these devices for precise measurements to ensure that the test results are both accurate and reliable.

In addition, engineers also combined the actual test cases of IGBT (insulated gate bipolar transistor) and SiC (silicon carbide) devices to give students a more intuitive understanding of the characteristics and application scenarios of new power devices. By comparing the test results, students can more intuitively understand the differences in characteristic parameters of the new generation of power devices and the advantages they bring to product design. As a third-generation semiconductor material, SiC has the advantages of high thermal conductivity, high breakdown field strength, high saturated electron drift rate and high bonding energy, and exhibits excellent performance under harsh conditions such as high temperature, high power, high voltage, high frequency and radiation resistance.

In the actual test session, the students had the opportunity to personally experience Tektronix's advanced test equipment and the entire process from equipment setup to data acquisition. Tektronix engineers also emphasized the control of noise and interference during the test process, as well as how to optimize the accuracy of the test signal. Through these practical operations, the students not only enhanced their theoretical knowledge, but also gained valuable practical experience.

This visit not only gave the undergraduate students of Beijing Jiaotong University a deeper understanding of the third-generation semiconductor power devices, but also laid a solid foundation for their academic research and future careers. The Tektronix Advanced Semiconductor Open Lab, with its openness, advancement and localized services, provides a valuable learning and communication platform for students. At the same time, Zhu Runfeng, manager of Beijing Kehua New Energy Measurement and Control Technology Co., Ltd., a full-set solution provider for testing and simulation in the new energy and energy storage industry, also accompanied the students throughout the exchange and exchanged views with the students on the current status of the industry and future opportunities and challenges.

Conclusion

With the continuous development of third-generation semiconductor technology, the demand for related technical talents is growing. This time exchange activity jointly organized by Tektronix Advanced Semiconductor Open Lab and the School of Electrical Engineering of Beijing Jiaotong University not only enhanced the communication and interaction between the school and the industry, but also enhanced the students' understanding of the third-generation semiconductor power device testing technology, and prepared them for the related fields they may work in in the future. Tektronix Advanced Semiconductor Open Lab will continue to play its leading role in the industry and contribute to the development of China's semiconductor industry.
