ABSTRACT:
An x-ray metrology system includes one or more transmissive x-ray optical elements, such as zone plates or compound refractive x-ray lenses, to shape the x-ray beams used in the measurement operations. Each transmissive x-ray optical element can focus or collimate a source x-ray beam onto a test sample. Another transmissive x-ray optical element can be used to focus reflected or scattered x-rays onto a detector to enhance the resolving capabilities of the system. The compact geometry of transmissive x-ray optical element allows for more flexible placement and positioning than would be feasible with conventional curved crystal reflectors. For example, multiple x-ray beams can be focused onto a test sample using a transmissive x-ray optical element array. Robust zone plates can be efficiently produced using a damascene process.
