The Department of Electrical Engineering has been established since 1976. Its postgraduate programs leading to Master and Doctor degrees were initiated in 1977 and 1983, respectively. To meet the demands by local industry for engineers in microelectronics and communications, the Institute of Electronic Engineering and the Institute of Communications Engineering were established in 1996 and 1999,respectively. Both of them offer Master and Doctor degrees as postgraduate research programs. To face the growing challenges in electronics and information technologies in the new (21st) millennium, the Department of Electrical Engineering are merged, in 1998, with the Department of Computer Science to constitute the College of Electrical Engineering and Computer Science (EECS). The constitution of the college helps not only to strengthen research capabilities and broaden research areas, but also to achieve a better usage and distribution of resources. Furthermore, the Institute of Photonics Technologies was established in August, 2003, to provide interdisciplinary programs about photonics technologies. In addition to the institutes, faculty members in the department have involved deeply in the foundation and research activities of several advanced research centers in the NTHU, such as the Center for IC Design Technology,the Center for Power Engineering, the Computer and Communication Research Center (CCRC), and Multimedia Technology Research Center.

In undergraduate programs, the department emphasizes on a balanced training on both theoretical studies and hands-on experiments. Students are encouraged to take inter-disciplinary courses, as well as to be involved in research projects. The undergraduate curriculum contains seven engineering modules, which are optoelectronics and electromagetics, solid-stateelectronics, electronic circuit design, computers, control systems, communication systems, signal processing, and power engineering. On top of regular laboratory courses, students are also required to take a team project to design and complete a simple electronic system during a senior year. In postgraduate programs, the ultimate goal is to incubate competent engineers who are capable of doing R&D works independently after graduation. Faculty members in the department have conduct research projects actively in a broad range of research fields, such as power systems, power electronics, communication systems, image processing, speech processing, VLSI design and testing, optoelectronics, and lasers. The annual research grants won by the dept. amounts to more than NT$100 millions.

The department also offers training programs for engineers and technicians coming from semiconductor industry, and participating actively in inter-disciplinary programs, such as the "semiconductor industry and fabrication" program and "micro-system science and technology" program in the NTHU. Together with ordinary postgraduate programs, these programs provide postgraduate students with inter-disciplinary training in a broad field of electronics-related research.

The department has a well-equipped microelectronic fabrication and characterization laboratory for both teaching and research activities in microelectronics. Following the establishment of the Center of Nano-Science and Technology, a new clean room for housing state-of-arts VLSI processing and MEMS fabrication facilities has also been built. All these add to boost the teaching and research energy of the department to its excellence.

The Department Office of Electrical Engineering (including Institute of Electronics Engineering, Institute of Communications Engineering and Institute of Photonics Technologies) have relocated to the Delta Building.
