Abstract
The electronic substrate used for the MEMS device is finely processed, and imprint lithography is often used as a processing method. However, in the printing process, gas is caught in the molding material, and transfer failure frequently occurs. Therefore, in this study, a gas permeable metal plate with a gas permeable structure inside was fabricated and imprinted on a material to be transferred containing 50% of volatile material. As a result, no gas pool was observed and imprinting was possible without defective transfer. This not only prevents entrainment of gas at the time of imprinting, but also a transfer material containing a volatile solvent can be used as a material to be transferred. It is greatly expected that the developed gas permeable metal plate becomes a material necessary for MEMS device processing.
