Abstract: A phase contrast x-ray microscope has a phase plate that is placed in proximity of and attached rigidly to the objective to form a composite optic. This enables easier initial and long-term maintenance of alignment of the microscope. In one example, they are fabricated on the same high-transmissive substrate. The use of this composite optic allows for lithographic-based alignment that will not change over the lifetime of the instrument. Also, in one configuration, the phase plate is located between the test object and the objective.

Abstract: A charge pump circuit for generating an output voltage is described. Charge pump circuits typically have two branches. As the clocks supplying the branches of a charge pump circuit alternate, the output of each branch will alternately provide an output voltage, which are then combined to form the pump output. The techniques described here allow charge to be transferred between the two branches, so that as the capacitor of one branch discharges, it is used to charge up the capacitor in the other branch. An exemplary embodiment using a voltage doubler-type of circuit, with the charge transfer between the branches accomplished using a switch controller by a boosted version of the clock signal, which is provided by a one-sided voltage doubler.

Abstract: CD-GISAXS achieves reduced measurement times by increasing throughput using longer wavelength radiation (˜12×, for example) such as x-rays in reflective geometry to increase both the collimation acceptance angle of the incident beams and the scattering signal strength, resulting in a substantial combined throughput gain. This wavelength selection and geometry can result in a dramatic reduction in measurement time. Furthermore, the capabilities of the CD-GISAXS can be extended to meet many of the metrology needs of future generations of semiconductor manufacturing and nanostructure characterization, for example.
