Abstract: Methods and apparatuses for forming a patterned layer of material are disclosed. In one arrangement, a selected portion of a surface of a substrate is irradiated with electromagnetic radiation having a wavelength of less than 100 nm during a deposition process. Furthermore, an electric field controller is configured to apply an electric field that is oriented so as to force secondary electrons away from the substrate. The irradiation locally drives the deposition process in the selected portion and thereby causes the deposition process to, for example, form a layer of material in a pattern defined by the selected portion.

Abstract: A pellicle membrane for a lithographic apparatus, the membrane including uncapped carbon nanotubes. A method of regenerating a pellicle membrane, the method including decomposing a precursor compound and depositing at least some of the products of decomposition onto the pellicle membrane. A method of reducing the etch rate of a pellicle membrane, the method including providing an electric field in the region of the pellicle membrane to redirect ions from the pellicle, or heating elements to desorb radicals from the pellicle, preferably wherein the pellicle membrane is a carbon nanotube pellicle membrane. An assembly for a lithographic apparatus, the assembly including a biased electrode near or including the pellicle membrane or heating means for the pellicle membrane.
