PROBLEM TO BE SOLVED: To provide a lithographic treatment cell capable of reworking a defective wafer more efficiently and / or more quickly, and further provide a lithographic apparatus, a track, and a device manufacturing method. SOLUTION: A lot is loaded via an input / output port I / O1, and next a substrate is applied by a spin applying machine SC, and is exposed by a lithographic apparatus LA, and next is developed by a developing machine DE. Thereafter, the substrate which is already developed is measured or inspected by an integrated measurement device IM, and an acceptable substrate is sent to an input / output port I / O2, and the lot which is already treated is assembled before the lot is transported to another process. The substrate which is rejected by an inspection is, for example, branched to a rework station RW when one or more defects are detected. COPYRIGHT: (C)2005,JPO&NCIPI

PROBLEM TO BE SOLVED: To provide a method for measuring overlay and grating shape parameters using a lithographic technology and measurement of an angle-resolved spectrum in a pupil plane of a high numerical aperture lens during the manufacture of a device. SOLUTION: An apparatus and a method are provided for determining a property of a substrate by measuring, in the pupil plane of the high numerical aperture lens, an angle-resolved spectrum as a result of radiation being reflected off the substrate. The property may be angle and wavelength dependent and may include the intensity of TM- and TE-polarized light and their relative phase difference. COPYRIGHT: (C)2009,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a device inspection method which has solved the conventional defects. SOLUTION: In the method, an asymmetrical marker on a device to be inspected is included; the form of the asymmetrical marker depends on the parameters to be inspected; a first measurement value of the position of the marker is obtained by directing light at the marker and detecting the diffracted light of a specified wavelength or of a diffracted angle; a secondary measured value of the position of the marker which is obtained by detecting the diffracted light of a different wavelength or at a different diffracted angle; a comparison between the first and second measurement positions which is performed so as to determine a shift indicating the degree of asymmetry of the marker.

Abstract:
An apparatus and method to determine a property of a substrate by measuring, in the pupil plane of a high numerical aperture lens, an angle-resolved spectrum as a result of radiation being reflected off the substrate. The property may be angle and wavelength dependent and may include the intensity of TM- and TE-polarized light and their relative phase difference. The apparatus according to the invention may be used for calculating variations in substrate tilt by putting a shaped obscuration in the radiation beam and detecting changes in the width and shape of the shaped obscuration on the substrate caused by variations in the substrate tilt. The shaped obscuration may be a cross-hair or any other shape. The idea of measuring wafer tilt is based on the fundamental relation that a tilt in the wafer plane causes a shift in the pupil plane.
