The use of conventional semiconductor process and other microfabrication technologies to create miniaturized sensors, actuators, and structures has become increasingly accepted in many areas of science and engineering. This course is interdisciplinary nature of micromachining techniques and their applications. Use of these technologies has resulted in an unprecedented range of devices that can be employed in applications through either displacement of macroscopic competitors or by enabling functions that are impossible. In addition to the micro science and engineering lecture, the course will also provide lab project for simplified hands-on experiment to gain practical sense of micro world.
