Abstract
Downsizing fabrication system is important for industry in cost efficiency. Modification and micro process of micro scale material is also important. In this study, we propose ″Cell in Micro-factory System″, which processes and fabricates microstructure in a micro cell. As the first step, in order to develop processing tools of this system, we experimentally study feasibility of a new processing method using a photo catalyst, TiO2, nano particle as a processing tool, which is excited with light energy.
