    摘要: This disclosure includes an imaging system that is configured to image in parallel multiple focal planes in a sample uniquely onto its corresponding detector while simultaneously reducing blur on adjacent image planes. For example, the focal planes can be staggered such that fluorescence detected by a detector for one of the focal planes is not detected, or is detected with significantly reduced intensity, by a detector for another focal plane. This enables the imaging system to increase the volumetric image acquisition rate without requiring a stronger fluorescence signal. Additionally or alternatively, the imaging system may be operated at a slower volumetric image acquisition rate (e.g., that of a conventional microscope) while providing longer exposure times with lower excitation power. This may reduce or delay photo-bleaching (e.g., a photochemical alteration of the dye that causes it to no longer be able to fluoresce), thereby extending the useful life of the sample.

    摘要: Methods and systems for solving measurement models of complex device structures with reduced computational effort and memory requirements are presented. The computational efficiency of electromagnetic simulation algorithms based on truncated spatial harmonic series is improved for periodic targets that exhibit a fundamental spatial period and one or more approximate periods that are integer fractions of the fundamental spatial period. Spatial harmonics are classified according to each distinct period of the target exhibiting multiple periodicity. A distinct truncation order is selected for each group of spatial harmonics. This approach produces optimal, sparse truncation order sampling patterns, and ensures that only harmonics with significant contributions to the approximation of the target are selected for computation. Metrology systems employing these techniques are configured to measure process parameters and structural and material characteristics associated with different semiconductor fabrication processes.

    摘要: An inspection apparatus comprises an illumination system (12) for illuminating a target structure with illuminating radiation and a collection system for collecting the illuminating radiation after it has been scattered by the target structure. A programmable spatial light modulator (713) comprises an array of movable mirror elements (742) in a conjugate pupil plane (P") of the illumination system. Between the array of mirror elements and the target a common optical path is defined forming part of the illumination system and the collection system. Each mirror element is movable between a first position where it reflects illuminating radiation into the common optical path and a second position where it reflects radiation from the common optical path toward a detector (19, 23). Various combinations of illumination aperture and collection aperture can be defined without the light losses associated with beam splitters and transmissive spatial light modulators.
