Abstract: A system detects targets located within patterns. It operates in the pupil plane by filtering the received signal from the surrounding pattern. A method includes illuminating a target and a surrounding pattern with radiation, detecting the radiation reflected by the target and the surrounding pattern and forming a first set of data based on the detected radiation, removing portions of the first set of data which correspond to the target to form reduced data, interpolating the remaining portions of the reduced data over the removed portions to form product data, and subtracting the product data from the first set of data to form target data.

Abstract: A system includes a support table having one or more protrusions and a pressure device. The one or more protrusions contact and support a substrate such that the substrate is suspended with respect to the support table. Sagging of the substrate when supported by the support table is based on a material and/or dimensions of the substrate. The pressure adjusts a pressure on a side of the substrate such that the sagging is reduced.

Abstract: Disclosed is a system configured to project a beam of radiation onto a target portion of a substrate within a lithographic apparatus. The system includes a radiation source. The radiation source includes a grating structure operable to suppress the zeroth order of reflected radiation for at least a first component wavelength. The grating structure has a periodic profile including regularly spaced structures providing three surface levels, such that radiation diffracted by the grating structure includes radiation of three phases which destructively interfere for at least the zeroth order of the reflected radiation for the first component wavelength. The grating structure is on a radiation collector within the source.

Abstract: A pellicle suitable for use with a patterning device for a lithographic apparatus. The pellicle comprising at least one breakage region which is configured to preferentially break, during normal use in a lithographic apparatus, prior to breakage of remaining regions of the pellicle. At least one breakage region comprises a region of the pellicle which has a reduced thickness when compared to surrounding regions of the pellicle.
