nano tech 2018: Seminar explores latest Gray Scale research work with the DWL 2000
Tokyo, Japan, February 6, 2018: This year marked the 17th edition of nano tech, the world’s premier nanotechnology exhibition, which was organized in Tokyo, Japan. Heidelberg Instruments joined over five hundred organizations from 24 countries and showcased its cutting-edge Maskless Aligner and Direct Write Laser Lithography systems.
Professor Kentaro Totsu, renowned researcher at the Tohoku University and the Deputy Director of the Micro System Integration Center, held a seminar outlining some of the current research in Gray Scale Lithography using the DWL 2000 Laser Lithography System, a high-resolution pattern generator designed and manufactured by Heidelberg Instruments. The Gray Scale Lithography is achieved by irradiating laser beam on a layer of thick positive. The amplitude of the laser beam and the position of the substrate are precisely controlled, simultaneously, by the system. Micro optical components, such as micro-lens arrays, micro-Fresnel lenses, and gratings are example of the gray scale lithography. During the presentation, a series of fabrication steps including gray scale file preparation, sample preparation, laser exposure, development, evaluation, and improvement of surface roughness of the photoresist was introduced.
