    Abstract: A sensor apparatus includes a sensor chip, an illumination system, a first optical system, a second optical system, and a detector system. The illumination system is coupled to the sensor chip and transmits an illumination beam along an illumination path. The first optical system is coupled to the sensor chip and includes a first integrated optic to configure and transmit the illumination beam toward a diffraction target on a substrate, disposed adjacent to the sensor chip, and generate a signal beam including diffraction order sub-beams generated from the diffraction target. The second optical system is coupled to the sensor chip and includes a second integrated optic to collect and transmit the signal beam from a first side to a second side of the sensor chip. The detector system is configured to measure a characteristic of the diffraction target based on the signal beam transmitted by the second optical system.

    Abstract: A patterning device support (200), for example, a patterning device (202) or substrate support, can be configured to release internal stresses of a patterning device loaded thereon. The patterning device support can include a positive pressuring generating interface (206a, 206b) or an acoustic vibration generating interface (206a, 206b), or can be configured to oscillate while at least a portion of patterning device is decoupled from the patterning device support. A method of transferring a patterning device between a patterning device handling apparatus and a patterning device support configured to move the patterning device can include positioning the patterning device onto a surface of the patterning device support, and performing a process that releases internal stress of the patterning device.

    Abstract: A lithographic apparatus includes an illumination system configured to condition a radiation beam, a support constructed to hold a patterning device, the patterning device being capable of imparting the radiation beam with a pattern in its cross-section to form a patterned radiation beam, a substrate table constructed to hold a substrate, and a projection system configured to project the patterned radiation beam onto a target portion of the substrate. The lithographic apparatus further includes an encoder head designed to scan over a surface of the patterning device to determine a distortion in a first direction along a length of the patterning device and a distortion in a second direction substantially perpendicular to the surface of the patterning device.

    Abstract: Systems, apparatuses, and methods are provided for measuring intensity using off-axis illumination. An example method can include illuminating a region of a surface of a substrate with a first radiation beam at a first incident angle and, in response, measuring a first set of photons diffracted from the region. The example method can further include illuminating the region with a second radiation beam at a second incident angle and, in response, measuring a second set of photons diffracted from the region. The example method can further include generating measurement data for the region based on the measured first set of photons and the measured second set of photons.

    Abstract: Described herein is a structure of the semiconductor device with a sub-segmented grating structure as a metrology mark and a method for configuring the metrology mark. A method for configuring a metrology mark may be used in a lithography process. The method includes determining an initial characteristic function of an initial metrology mark disposed within a layer stack. The method also includes perturbing one or more variables of the plurality of subsegments of the metrology mark (e.g., pitch, duty cycle, and/or line width of the plurality of subsegments) and further perturbing a thickness of one or more layers within the layer stack. The method further includes iteratively performing the perturbations until a minimized characteristic function of an initial metrology mark is determined to set a configuration for the plurality of subsegments.

    Abstract: Systems, apparatuses, and methods are provided for detecting a particle on a substrate surface. An example method can include receiving, by a grating structure, coherent radiation from a radiation source. The method can further include generating, by the grating structure, a focused coherent radiation beam based on the coherent radiation. The method can further include transmitting, by the grating structure, the focused coherent radiation beam toward a region of a surface of a substrate. The method can further include receiving, by the grating structure, photons scattered from the region in response to illuminating the region with the focused coherent radiation beam. The method can further include measuring, by a photodetector, the photons received by the grating structure. The method can further include generating, by the photodetector and based on the measured photons, an electronic signal for detecting a particle located in the region of the surface of the substrate.
