    摘要: An automated method for co-optimizing a scatterometry mark and a process monitoring mark is provided. Embodiments include generating a series of pattern profiles on a photoresist on a wafer; providing the series of pattern profiles, resist process parameters, and scatterometry critical dimension parameters as inputs for a scatterometry measurement; performing scatterometry measurement to generate spectra from the series of pattern profiles; and optimizing a sensitivity precision correlation for the resist process parameter.

    摘要: A liquid immersion scanning exposure system utilizes an immersion liquid confined within a watertight lens hood having a base portion formed from a solid optical element. During operation, a bottom portion of a lens assembly is disposed within the immersion liquid and the solid optical element is placed upon a photoresist material or layer (to be patterned). The lens assembly moves laterally through the immersion liquid parallel to the photoresist material. Because the solid optical element separates the immersion liquid from the photoresist material and does not move relative to the photoresist material, the photoresist material does not contact with the immersion liquid and the solid optical element and is not susceptible to damage or scratching by the solid optical element.
