Abstract:
A method for scanning an object, the method may include moving an object by a first mechanical stage that follows a first scan pattern; introducing multiple movements, by a second mechanical stage, between the object and the first mechanical stage while the first mechanical stage follows the first scan pattern; and obtaining, by optics, images of multiple suspected defects while the first mechanical stage follows the first scan pattern; wherein a weight of the first mechanical stage exceeds a weight of the second mechanical stage.
Abstract:
There may be provided an evaluation system that may include spatial sensors that include atomic force microscopes (AFMs) and a solid immersion lens. The AFMs are arranged to generate spatial relationship information that is indicative of a spatial relationship between the solid immersion lens and a substrate. The controller is arranged to receive the spatial relationship information and to send correction signals to the at least one location correction element for introducing a desired spatial relationship between the solid immersion lens and the substrate.
Abstract:
Apparatus for cleaning a surface of a substrate (105) includes a cooling device (130), which is adapted to cool a region of the substrate in a vicinity of a particle on the surface, so as to cause a fluid in contact with the surface to form a frozen film (140) in the vicinity of the particle. A radiation source (150) is adapted to direct a beam of energy (155) toward the surface so as to cause vaporization of the film due to absorption of the beam in the film, thereby facilitating removal of the particle from the surface.
Abstract:
A system for coupling a mask to a mask holder. The system includes a base, an aperture; mask holder cover supporting elements arranged to move between a first position and a third position while supporting the mask holder cover; mask supporting elements arranged to move between a fourth position and a sixth position while supporting the mask; mask holder base supporting elements arranged to support the mask holder base. When the mask holder cover supporting elements are at the first position and the mask supporting elements are at the third position the mask holder cover, the mask and the base are spaced apart from each other. When the mask holder cover supporting elements are at the third position and the mask supporting elements are at the sixth position the mask holder cover, the mask and the base are connected to each other.
Abstract:
Chamber elements defining a chamber include a first element having a first surface, a second element, a first dynamic seal and load mechanism. The second element includes an outer floating element that includes a second surface about the periphery of the chamber, and an inner floating element. The second surface and the first surface are maintained proximate to each other when the chamber is in a load position and when the chamber is closed. The load mechanism may move the inner floating element from the outer floating element until a gap between the inner floating element and the second element to facilitate loading of the device to the chamber. A movement system may generate relative movement between the first element and the second element.
Abstract:
Apparatus (20) for processing a surface (21) of a substrate (22) includes a chamber (26) containing a cavity (33) that has one side that is open, the chamber (26) wall including a lip (31) surrounding the open side of the cavity (33). Gas ports, disposed within the chamber (26) wall and opening through the lip (31), emit a pressurized gas so as to create a gas cushion between the lip (31) and the surface (21) when the open side of the cavity (33) is placed adjacent to the surface (21), thus creating a seal between the cavity (33) and an environment external to the chamber (26).
