Abstract: A system for providing flexible optical aperture shapes in an optical inspection system (e.g., an optical wafer inspection system) is described. The system includes one or more mechanisms for providing multiple optical aperture shapes along an optical beam path in the optical wafer inspection system. The multiple optical apertures shapes are stacked or overlapped to combine the shapes and form a single combined optical aperture shape along the optical beam path.

Abstract: Methods and systems for reconfiguring an aperture of an optical inspection system are presented. A programmable aperture system includes a two dimensional array of mechanical pixels that selectively block light passing through the aperture. An array of linear guiding elements is aligned parallel to one another, and each row of mechanical pixels is supported by a corresponding linear guiding element. Each mechanical pixel is configured to slide along the corresponding linear guiding element when pushed by an actuator subsystem. The actuator subsystem repositions one or more of the mechanical pixel elements to change the shape of the aperture. The actuator subsystem is configured to selectively engage one or more mechanical pixel elements and translate the one or more mechanical pixel elements along corresponding linear guiding elements to a new position.

Abstract: A fluid input manifold distributes injected fluid around the body of a bulb to cool the bulb below a threshold. The injected fluid also distributes heat more evenly along the surface of the bulb to reduce thermal stress. The fluid input manifold may comprise one or more airfoils to direct a substantially laminar fluid flow along the surface of the bulb or it may comprise a plurality of fluid injection nozzles oriented to produce a substantially laminar fluid flow. An output portion may be configured to facilitate fluid flow along the surface of the bulb by allowing injected fluid to easily escape after absorbing heat from the bulb or by applying negative pressure to actively draw injected fluid along the surface of the bulb and away.

Abstract: In an optical inspection tool, an illumination aperture is opened at each of a plurality of aperture positions of an illumination pupil area one at a time across the illumination pupil area. For each aperture opening position, an incident beam is directed towards the illumination pupil area so as to selectively pass a corresponding ray bundle of the illumination beam at a corresponding set of one or more incident angles towards the sample and an output beam, which is emitted from the sample in response to the corresponding ray bundle of the incident beam impinging on the sample at the corresponding set of one or more incident angles, is detected. A defect detection characteristic for each aperture position is determined based on the output beam detected for each aperture position. An optimum aperture configuration is determined based on the determined defect detection characteristic for each aperture position.
