摘要:
An imaging device for forming an image of a sample object includes an optical device and a processing unit. The optical device captures a Fourier spectrum of an object. The processing unit is arranged for processing the Fourier spectrum from the optical device and is adapted for determining the image of the sample object from the intensity of the Fourier spectrum of the sample object and the intensity of the Fourier spectrum of a combination of the sample object and a reference object.

A lithographic apparatus includes a source for generating radiation, an illumination system for conditioning the radiation, a patterning device for patterning the conditioned radiation, and a projection system for projecting the patterned radiation onto a target portion of a substrate. The illumination system includes a debris mitigating system for mitigating debris particles that are released with the generation of radiation, and an optical system for collecting the radiation. The debris mitigation system is arranged to directly evaporate the debris particles, or to directly charge the debris particles, or to directly produce a plasma out of the debris particles, or any combination thereof, in a path along which the radiation propagates from the source to the optical system.
摘要:
The invention relates to a multivariate calibration which can be used when the optical system used for that method does not comprise a multi-channel detector such as a CCD sensor or a line array of photodiodes. An optical system without a multi-channel detector doesn't allow to carry out preprocessing steps. Thus there is the need to carry out these preprocessing steps in another way. It is suggested to partially replace the preprocessing step by a measurement of the optical signal, whereby the measurement comprises transmitting or reflecting the optical signal by an optical element, thereby weighing the optical signal by a spectral weighing function. The advantage of the invention is to teach how such an optical system without a bulky and expensive CCD sensor can be used to carry out a multivariate calibration and preprocessing steps.

A liquid supply system for an immersion lithographic projection apparatus is disclosed in which a space is defined between the projection system, a barrier member and a substrate. The barrier member is not sealed such that, during use, immersion liquid is allowed to flow out the space and between the barrier member and the substrate.
摘要:
A lithographic projection apparatus is disclosed in which a space between the projection system and the substrate is filled with a liquid. An edge seal member at least partly surrounds the substrate or other object on a substrate table to prevent liquid loss when edge portions of the substrate or other object are, for example, imaged or illuminated.

摘要:
An imaging apparatus is disclosed for combined temperature and luminescence spatial imaging of an object (1), such as a bio-array for detection of biological molecules. Light (5) is separated into a first (10) and a second (20) optical path, where the first optical path (10) guides infrared (IR), and the second optical path (20) guides luminescence light, preferably fluorescence light, from the object (1). Image intensifying means (30) converts infrared light (10a) in the first optical path into intensified light (10b), preferably visible light. Photo detection means (100) are arranged for spatial imaging of the object (1), the photo detection means being arranged for alternately receiving light from the first (10) and the second (20) optical path. Processing means (200) are capable of combining a temperature image (11) with a luminescence image (21) so as to obtain a combined image (25) of the object with a direct spatial correspondence between the two images. For bio-arrays this provides many advantages in relation to combined imaging of an array, whereupon numerous probe molecules are located.
