Images of areas of a wafer are generated and registered with respect to computer aided design (CAD) data to provide a registered images. Defects in the wafer are then detected by comparing the registered images to one another and defect location information is generated in CAD coordinates.
摘要:
A photovoltaic assembly has elongated photovoltaic modules. The photovoltaic modules each have a substrate with a photovoltaic material disposed on the substrate. Each respective photovoltaic module lies in the concave structure of a corresponding concentrator assembly. The concentrator assemblies have surfaces made with reflective material that form such concave structures. The concentrator assemblies each transmit light to their corresponding photovoltaic module. The surfaces of each concentrator assembly are shaped at least in part as an involute of the surface of their corresponding photovoltaic modules, and do not exceed the height of the their corresponding module. A frame is provided having a first support and a second support, where the modules extend between the supports. The concentrator is mechanically attached to the frame. A substantial portion of light striking the concentrator is ultimately redirected to the modules without associated tracking and/or control devices.

The system is also movable.
摘要:
Methods and apparatus to facilitate the measurement of the amount of scattered electrons collected by an anti-fogging baffle arrangement are provided. For some embodiments, by affixing a lead to an electrically isolated (floating) portion of the baffle arrangement, the amount of scattered electrons collected thereby may be read out, for example, as a current signal. Thus, for such embodiments, the baffle arrangement may double as a detector, allowing an image of surface (e.g., a mask or substrate surface) to be generated.
摘要:
An apparatus for converting light energy into electric energy has a concentrator with at least a first and second wall. The walls are made at least in part of a material that reflects light. The concentrator has an opening defined by the walls, and is operable to admit light energy into an interior portion of the apparatus. An elongated photovoltaic module is disposed between the walls. The module has a substrate, and a photovoltaic covering disposed on the substrate. The module can generate electric energy from light energy that directly strikes the module and light energy redirected from the concentrator to the module. The walls are substantially the shape of an involute of the module. The walls are limited to the height of the topmost portion of the elongated photovoltaic module. The module is disposed upon or above a joining of the walls.
