Abstract
The invention relates to a reinforcing structure for a thin film, particularly for an ultrathin film permeable to X-ray and ultraviolet radiation, and a method for manufacturing a reinforcing structure for a thin film with a thickness less than 5 micrometers. According to the invention, on the surface of the thin film, there is formed, in a bakeing treatment of at least one step, a reinforcing structure made of some photosensitive material such as polymer.
