Abstract: A micromirror array comprises a substrate, a plurality of mirrors for reflecting incident light and, for each mirror of the plurality of mirrors, at least one piezoelectric actuator for displacing the mirror, wherein the at least one piezoelectric actuator is connected to the substrate. The micromirror array further comprises one or more pillars connecting the mirror to the at least one piezoelectric actuator. Also disclosed is a method of forming such a micromirror array. The micromirror array may be used in a programmable illuminator. The programmable illuminator may be used in a lithographic apparatus and/or in an inspection and/or metrology apparatus.

Abstract: A method for forming a pellicle for use in a lithographic apparatus is disclosed. The method includes: providing a porous membrane formed from a first material; applying at least one layer of two-dimensional material to at least one side of the porous membrane; and applying a capping layer to the at least one layer of two-dimensional material on at least one side of the porous membrane such that the at least one layer of two-dimensional material is disposed between the or each capping layer and the porous membrane. The at least one layer of two-dimensional material may act to close the adjacent side of the porous membrane and to form a smoother and flatter exterior surface of the pellicle. Advantageously, this may allow the porous membrane to be protected from etching while reducing EUV flare, regardless of the material used for the capping layer.

Abstract: Methods and apparatus for forming a patterned layer of material are disclosed. In one arrangement, a selected portion of a surface of a substrate is irradiated during a deposition process, the irradiation being such as to locally drive the deposition process in the selected portion to form a layer of deposited material in a pattern defined by the selected portion. The deposited material is annealed to modify the deposited material.
