Shared readout low noise global shutter image sensor method
A method for operating a global shutter image sensor includes performing both a global shutter (image capture) operation and a rolling shutter (readout) operation. During the global shutter operation, image information (charges) are captured by photodiodes in every pixel, and then simultaneously transferred to charge coupled gate (ccg) devices provided in each pixel.

Estimating molecular size distributions in formation fluid samples using a downhole nmr fluid analyzer
A method for estimating a property of subsurface material includes extracting a sample of the material using a downhole formation tester and performing a plurality of nuclear magnetic resonance (nmr) measurements on a sensitive volume in the sample where each measurement in the plurality is performed in a static homogeneous magnetic field with a pulsed magnetic field gradient that is different in magnitude from other nmr measurements to provide a waveform signal. The method further includes transforming each received waveform signal from a time domain into a frequency domain and comparing the frequency domain signal to a reference to provide proton chemical-shift information related to a chemical property of one or more molecules in the sample and transforming the frequency domain signals into a complex number domain that quantifies waveform signal amplitude changes to provide one or more diffusion rates with each diffusion rate being associated with a corresponding frequency..

Semiconductor device and method for manufacturing semiconductor device
During the production of a semiconductor device having a cu wiring line of a damascene structure, diffusion of fluorine from a cf film that serves as an interlayer insulating film is prevented in cases where a heat treatment is carried out, thereby suppressing increase in the leakage current. A semiconductor device of the present invention having a damascene wiring structure is provided with: an interlayer insulating film (2) that is formed of, for example, a fluorine-added carbon film; and a copper wiring line (4) that is embedded in the interlayer insulating film.
