Innovative Master’s Program at PolyU Advances Microelectronics

The Hong Kong Polytechnic University (PolyU) has launched an innovative Master’s programme in microelectronics technology and materials, spearheaded by Professor Zhao Jiong. This initiative aims to equip students with essential skills and knowledge to excel in a rapidly evolving sector known for its continuous innovation and efficiency improvements.

The programme, delivered by the Department for Applied Physics, focuses on the latest advancements in microelectronics, particularly in 2D ferroelectronics. As Professor Zhao notes, “The programme provides students with all the key skills they need to work in microelectronics, such as circuit design, materials processing and failure analysis.” Students also benefit from direct collaboration with over 20 faculty members who are engaged in cutting-edge research beyond traditional silicon technologies.

Hands-On Learning Experience

What sets this Master’s programme apart is its dual emphasis on electronics engineering and materials science. This approach ensures that students gain a comprehensive understanding of the semiconductor materials and device structures pivotal to mass-produced integrated circuits. Practical experience is a cornerstone of the curriculum, with students regularly participating in experimental work that involves fabricating and testing electronic devices.

“Our cleanroom laboratory is equipped with instruments for microfabrication, including thin-film deposition, etching, and photolithography,” Professor Zhao explains. This state-of-the-art facility allows students to gain hands-on experience with various techniques, such as sputtering and molecular beam epitaxy, crucial for modern microelectronics.

In one module focused on materials analysis, students analyze the layered structure of standard computer chips, using advanced tools like scanning electron microscopes. This practical knowledge is invaluable for their future careers.

Students also receive training in circuit design through advanced software tools that facilitate the configuration, simulation, and analysis of complex electronic layouts. Professor Dai Jiyan, Associate Dean of Students at PolyU, emphasizes, “Through this experimental work, students gain the technical skills they need to design and fabricate integrated circuits, optimizing their performance and reliability.”

Integrating Artificial Intelligence

The integration of artificial intelligence into the curriculum further distinguishes this Master’s programme. AI applications, such as defect analysis and materials selection, are introduced to students, enhancing their understanding of how computational methods are transforming the microelectronics landscape. PolyU has established a joint laboratory with Huawei to explore AI applications in electronic design, providing students with early exposure to these emerging technologies.

“Two of the modules are directly related to AI, while the joint lab with Huawei allows students to experiment with using AI in circuit design,” Professor Dai notes. This forward-thinking approach ensures that graduates are well-prepared to meet the demands of the industry.

The programme, now in its third year, was developed in collaboration with the Applied Science and Technology Research Institute (ASTRI). Established in 2000, ASTRI aims to enhance Hong Kong’s competitiveness through advanced technologies. Students benefit from guest lectures and guidance from ASTRI researchers, who also contribute specialized instruments for laboratory work.

Once equipped with foundational knowledge, students can engage in short research projects alongside faculty members. They can choose to focus on relevant manufacturing topics or investigate emerging materials and devices, including applications in solar cells and neuromorphic computing. Professor Zhao highlights the importance of these projects, stating, “They learn more about the research process, which can make them more confident to take their studies to the next level.”

Career Opportunities and Industry Connections

The programme offers numerous pathways for students interested in industry careers. Huawei supports the initiative by arranging visits to its manufacturing facilities and offering internships. PolyU also organizes visits to Hong Kong’s Science Park, where multinational companies and start-ups operate in the microelectronics sector. These connections can lead to research support and internship opportunities for students.

The international focus of PolyU’s Master’s programme has attracted a diverse student body, particularly from mainland China. Both Professor Zhao and Professor Dai believe that the comprehensive curriculum will appeal to graduates from across Asia and beyond. “Through the programme, the students gain knowledge about all aspects of the microelectronics industry and how it is likely to evolve,” says Professor Dai.

With a rich blend of theoretical knowledge, practical experience, and industry connections, this Master’s programme positions students for success in the competitive microelectronics field, whether they choose to enter the workforce or pursue further research studies.
