Abstract: Disclosed are systems and methods for object inspection, in particular for inspection of reticles used in a lithography process. The method includes interferometrically combining a reference radiation beam with a probe radiation beam, and storing their complex field images. The complex field image of one object is then compared with that of a reference object to determine the differences. The systems and methods have particular utility in the inspection of a reticle for defects.

Abstract: A method of controlling fuel supplied to an engine is provided. In one example, a cylinder includes port and direct fuel injection. The method includes supplying a second fuel type from a second tank to the direct injector and supplying a first fuel type from a first tank to the port injector; and responsive to mis-fueling, supplying the first fuel type from the first tank to the direct injector.

Abstract: A patterning device, including alignment targets having alignment features formed from a plurality of diffractive elements, each diffractive element including an absorber stack and a multi-layered reflector stack is provided. The diffractive elements are configured to enhance a pre-determined diffraction order used for pre-alignment and to diffract light in a pre-determined direction of a pre-alignment system when illuminated with light of a wavelength used for the pre-alignment.

The diffractive elements may be configured to enhance first or higher order diffractions, while substantially reducing zeroth diffraction orders and specular reflection when illuminated with a wavelength used for reticle prealignment. The dimensions of each diffractive element may be a function of a diffraction grating period of each alignment feature.

Abstract: A method and systems for reticle inspection. The method includes coherently illuminating surfaces of an inspection reticle and a reference reticle, applying a Fourier transform to scattered light from the illuminated surfaces, shifting the phase of the transformed light from the reference reticle such that a phase difference between the transformed light from the inspection reticle and the transformed light from the reference reticle is 180 degrees, combining the transformed light as an image subtraction, applying an inverse Fourier transform to the combined light, and detecting the combined light at a detector. An optical path length difference between two optical paths from the illumination source to the detector is less than a coherence length of the illumination source. The image detected by the detector represents a difference in amplitude and phase distributions of the reticles allowing foreign particles, defects, or the like, to be easily distinguished.
