| Outline of Final Research Achievements |
In conventional micropatterns have been fabricated by several processes such as lithography and etching, which generate a large amount of waste liquid, or by inkjet printing, which produces a small amount of waste liquid but is not so fine. On the other hand, we have developed a direct photofabrication process for functional materials only by light irradiation. This process is based on the findings of unique phenomenon that occurs in the laser focus. In this study, we investigated this phenomenon to understand the mechanism. Detailed observation with high-speed camera and heat transfer simulation indicated the validity of our proposed physical mechanism model. Two phenomena with large time difference proceeded during the laser writing. From this understanding the mechanism, we newly developed another laser writing process with high efficiency.
