摘要:
A device manufacturing method includes conditioning a beam of radiation using an illumination system. The conditioning includes controlling an array of individually controllable elements and associated optical components of the illumination system to convert the radiation beam into a desired illumination mode, the controlling including allocating different individually controllable elements to different parts of the illumination mode in accordance with an allocation scheme, the allocation scheme selected to provide a desired modification of one or more properties of the illumination mode, the radiation beam or both. The method also includes patterning the radiation beam having the desired illumination mode with a pattern in its cross-section to form a patterned beam of radiation, and projecting the patterned radiation beam onto a target portion of a substrate.

摘要:
A device manufacturing method is disclosed in which the aberration of the projection system of a lithographic projection apparatus is obtained in terms of the Zernike expansion. The field distribution of displacement error and focal plane distortion of the projected image are calculated on the basis of the Zernike aberration and sensitivity coefficients which quantify the relationship between Zernike aberration components and the error in the image. A calculation is then performed to determine the compensation to apply to the apparatus in order to minimize the error in the image. The compensation is then applied to the apparatus. The compensation may comprise increasing one component of aberration of the apparatus in order to decrease the effect of another aberration, such that, on balance, the image quality as a whole is improved.

摘要:
A lithographic apparatus has an assembly to exchange optical elements in a pupil plane of its projection system. The optical elements may be pupil filters and may conform to the physical dimensions specified for a reticle standard, e.g. having sides substantially equal to 5, 6 or 9 inches.
