  • METHOD OF FABRICATING POROUS FILM STRUCTURE USING DRY PROCESSES AND POROUS FILM STRUCTURES FABRICATED BY THE SAME
    Publication number: 20130052475
    Abstract: Provided are a method of fabricating a porous thin film structure, by forming a thin film from at least two elements, followed by selectively removing the certain element using a dry etching process, and a porous thin film structure fabricated by the same. Because all processes of the method of fabricating a porous thin film structure are dry processes, process control is simply accomplished, environmental impact is low, and mass production is possible, in contrast to when using a typical wet process such as electrodeposition or dealloying. Also, since a level of porosity is easily controlled and maintained uniform, a mesoporous thin film structure showing a reproducible level of sensitivity when used as a sensor can be fabricated.
