Abstract:
1. A method of irradiating a surface of a photosensitive layer (L 2 ) on a substrate (L 1 ) immersed in a fluid (L 3 ), where said irradiation is performed through a removable transparent spacer layer (L 4 ) to pattern said photosensitive layer (L 2 ), the method comprising: applying said photosensitive layer (L applying a removable protective transparent layer (L immersing the removable protective transparent layer (L projecting electromagnetic radiation at a first wavelength onto the top surface of the photosensitive layer (L altering the solubility of the removable protective transparent layer (L dissolving the removable protective transparent layer (L wherein the thickness of the removable protective transparent layer (L
