  • Patent number: 8339183
    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.

  • Patent number: 7920676
    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.
