Abstract: An attenuation filter is configured to define attenuation of the intensity of ultraviolet radiation with a specified working wavelength from a wavelength range of 150-370 nm according to a specifiable local distribution in a projection lens of a microlithographic projection exposure apparatus. The attenuation filter has a substrate and an absorption layer on the substrate. The substrate is sufficiently transparent at the working wavelength. The absorption absorbs incident ultraviolet radiation of the working wavelength according to the specifiable local distribution at different locations of a used area to varying degrees. The attenuation filter reduces or avoids a thermally induced wavefront variation error in the ultraviolet radiation which has passed through the attenuation filter owing to locally varying heating of the substrate, which is caused by the absorption of the ultraviolet radiation that varies locally over the substrate. A thickness of the substrate is less than 100 ?m.

Abstract: Tunable filters can use Fano metasurface designs having extremely narrow transmission bands. The Fano metasurface can comprise dielectric or semiconductor materials and can produce transmission bands with quality factors well in excess of 1000—at least a factor of 50 greater than typical metamaterial-based infrared resonances. Numerical simulations of these metasurfaces show that the spectral position of the passband can be changed by slightly changing the position of a small dielectric perturbation block placed within the near-field of the resonator by using simple electromechanical actuation architectures that allow for such motion. An array of independently tunable narrowband infrared filters can thereby be fabricated that only requires deep-subwavelength motions of perturbing objects in the resonator's near-field.

Abstract: In the step of curing a resin for bonding a TFT substrate and a counter substrate each having an alignment film that has been optically aligned by using UV-light, damage to the alignment film due to the UV-light can be prevented without using a light shielding mask. A UV-light absorption layer is formed between each black matrix on the counter substrate. The TFT and counter substrates are sealed at their periphery by a resin that is cured by UV-light radiated from the counter substrate side. Since the absorption layer has a high absorbability to UV-light at a wavelength of 300 nm or less that degrades the alignment film, damage to the alignment film due to the UV-light for curing the resin can be prevented. Thus, provision of a light shielding mask for shielding the UV-light for the display region can be saved.
