  • Patent number: 11976325
    Abstract: The invention provides systems and methods for making sequencing libraries that are useful for quantitatively analyzing nucleic acids in a sample. Sample nucleic acids are randomly cleaved at, and PCR handled are attached to, a random cut site. The nucleic acid is amplified into a sequencing library in which a sequencing primer generates a sequence read from adjacent the random cut site. The sequence reads can be mapped to a reference, but they will also include a unique identifier sequence that comes from within the nucleic acid molecule being analyzed, i.e., an intrinsic molecular identifier (IMI). The IMI is unique for each molecule and can thus be used to deduplicate sequence reads originating from the same molecule.

  • Patent number: 11300502
    Abstract: A time-wavelength optical sampling system may be configured to determine a substance's composition based on variations in optical pulses caused by the substance's absorption of wavelengths of the pulse. A dispersion medium may disperse pulses to form stretched signal pulses that are incident on a substance under test. Optical gating is used to overlap each signal pulse with a portion of a reference pulse to generate a cross-correlation signal corresponding to a portion of the signal pulse, which may be detected by a slow detection speed detector. A controller controls delay introduced to the reference pulses so that different wavelength ranges are sampled for various signal pulses, thereby enabling the entire wavelength range for the signal pulses to be sampled over time without requiring an expensive high-speed optical detector. By analyzing absorption across the entire wavelength range as indicated by cross-correlation signals, the composition of the substance can be identified.

    Abstract: A structure for grounding an extreme ultraviolet mask (EUV mask) is provided to discharge the EUV mask during the inspection by an electron beam inspection tool. The structure for grounding an EUV mask includes at least one grounding pin to contact conductive areas on the EUV mask, wherein the EUV mask may have further conductive layer on sidewalls or/and back side. The inspection quality of the EUV mask is enhanced by using the electron beam inspection system because the accumulated charging on the EUV mask is grounded. The reflective surface of the EUV mask on a continuously moving stage is scanned by using the electron beam simultaneously. The moving direction of the stage is perpendicular to the scanning direction of the electron beam.

  • Patent number: 9781362
    Abstract: An image sensor capable of capturing an image formed by a lens includes a substrate and a bonding wire. The substrate has a pixel array and a bonding pad on a top surface of the substrate between the pixel array and a substrate edge. The bonding wire is electrically connected to the bonding pad and has a region forming a non-zero angle with respect to the substrate top surface. The non-zero angle is in at least one of a lower and an upper angular range for minimizing reflection of incident light on the region from reaching the image sensor. The lower angular range is selected such that the region reflects the incident light away from the pixel array toward a plane including the lens. The upper angular range is selected such that the region reflects the incident light to a clearance between the bonding pad and the pixel array.
