Abstract

A method of micromachining polytetrafluoroethylene by applying radiation light to the surface of polytetrafluoroethylene, includes the steps of: preparing a workpiece including a region made of polytetrafluoroethylene; preparing a mask having patterned areas substantially transmitting and not transmitting the radiation light; and applying the radiation light containing at least ultraviolet rays of a wavelength of 160 nm to a surface of the workpiece through the mask. Polytetrafluoroethylene can be microscopically processed, while obtaining a high aspect ratio and processing a large area with ease.
