Dr. Jungkwun ‘JK’ Kim, Associate Progessor of Electrical Engineering Department at University of North Texas will give a seminar titled "Advanced 3D microlithography and its Bio/RF applications" to the interested faculty and students at Discovery Park.

Abstract

For decades, UV lithography has been the backbone of innovation in various technical fields, such as semiconductors, microelectronics, bio/optical sensors, and RF/microwave devices. Historically, UV lithography relied on mercury-based light sources, but with the advancement of UV-LED technology, new opportunities have emerged, particularly for 3D microfabrication. Despite its potential, UV-LED technology in the realm of microlithography is still in its early stages, and many of its capabilities remain underexplored. This presentation will delve into both the foundational principles and advanced techniques of microlithography, with a special focus on the fabrication of complex 3D microstructures. Highlighted will be a range of unique and intricate microstructures, including millimeter-tall micropillars, horns, and triangular slabs, which pose challenges for conventional methods due to selective UV transparency. Additionally, various 3D microdevices created through this advanced microlithography technique will be showcased, including microinductors designed for low-power DC-DC converters, 3D micromachined antennas for satellite communications, and diverse 3D microneedles for biomedical applications.
