VU Students Deepen Knowledge of Semiconductors in Taiwan
In December, students from the Faculty of Physics at vlog (VU) participated in a two‑week Taiwan–Europe Semiconductor Short‑Term Training Programme. Senior undergraduates Adomas Puluikis, Kasparas Stanaitis, Master’s student Karolina German, PhD students Kęstutis Žilinskas and Domantas Vizbaras gained experience in the field of semiconductors together with colleagues from Lithuania, Romania, Slovakia, Italy, the Czech Republic, and Kosovo.
Students improved their theoretical and practical knowledge in Tainan city, where they gained a comprehensive understanding of electronic‑component manufacturing, with a particular focus on MEMS gas detectors (Micro-Electro-Mechanical Systems, MEMS). “The activities included theoretical lectures on gas sensor systems and integrated circuit design, as well as laboratory classes where we learned the fundamentals of process engineering,” said K. Žilinskas.
At the National Institutes of Applied Research in Taiwan, participants learned about the basic principles of electronic circuit design, how MEMS gas detectors work and what determines their measurement accuracy and reliability. “We explored different signal amplification components and how detector performance is influenced by temperature, humidity, noise caused by internal components, and device ageing. This gave me a clearer understanding of the roles of individual electronic circuit elements and how a device’s performance changes through interaction with the environment,” said K. German.
The training at the Taiwan Semiconductor Research Institute (TSRI) focused on practical activities. “We became familiar with laboratory equipment and various stages of the manufacturing process, including photolithography, thin-film deposition, and etching processes. During the practical sessions, it was demonstrated how theoretical knowledge is applied in the development and testing of real detectors. Since I had the opportunity to carry out most of the manufacturing stages using equipment at VU, it was particularly interesting to learn about the methods used at TSRI and to compare which processes are performed in a similar way and which differ. Taiwan is strongly oriented towards industrial production, so even at the laboratory level all processes, especially during the lithography stage, are automated. As a result, the risk of human error is reduced,” said K. German.
According to the student, the final result of the manufacturing process is a set of microscale mechanical elements integrated into a single chip (integrated circuit) alongside electronic components such as resistors and capacitors. “These subsequent stages are still new to me, so I was glad to be able to see them and learn more about this field. It was particularly interesting to observe how individual micrometre-scale electronic components are physically integrated into a circuit while maintaining precision,” said K. German.
VU students noted that the training program provided valuable international experience and enabled them to gain closer insight into Taiwan’s science and technology infrastructure. The physicists acquired new knowledge and competencies that can be applied in their further studies. During the training, participants also became acquainted with Taiwan’s local culture and natural diversity. They were pleased to have the opportunity to establish valuable professional contacts and to meet Professor Shun-Fen Tzeng from National Cheng Kung University, who is also the Executive Director of the Science and Technology Division of the Taiwanese Representative Office in Lithuania.
K. Žilinskas was impressed by the Taiwanese work ethic, high level of organisation, and friendly environment. “This is a unique opportunity to combine high-level technical knowledge with cultural experience. Taiwan’s semiconductor industry is one of the world’s leaders, so this programme provided excellent opportunities for personal development,” he said.
K. German encourages all young researchers to seek opportunities to gain international experience abroad. “Taiwan is one of the leading countries in the semiconductor industry, so this and similar training programs provide an excellent opportunity to acquire new knowledge and practical skills,” the Master’s student said. Last summer, she took part in a visit focused on fostering academic and research cooperation .
A total of 59 students took part in the Taiwan–Europe Semiconductor Short‑Term Training Programme, including 15 Lithuanians from VU the Center for Physical Sciences and Technology, and Vilnius Gediminas Technical University.
