  • Publication number: 20240153980
    Abstract: The present application discloses a CMOS image sensor. A pixel cell circuit comprises a photodiode and a CMOS pixel readout circuit. The pixel cell circuit is formed on an SOI substrate, and the photodiode is formed on a bottom semiconductor substrate. The CMOS pixel readout circuit is formed on a top semiconductor substrate. A photo-induced carrier of the photodiode is connected to the CMOS pixel readout circuit by means of an electrotransfer structure passing through a dielectric buried layer. The present application also discloses a method for manufacturing a CMOS image sensor. The present application can increase a pixel cell density without reducing a photodiode area, thus achieving an ultra-high CMOS image sensor density and improving the device quality.

  • Publication number: 20240128296
    Abstract: The present application discloses a double-layer stacked CMOS image sensor, photo diode and transfer gate transistor of a pixel cell are formed on the first substrate sequentially along a longitudinal direction, and the other pixel transistors of the pixel cell are formed on the second substrate. The first substrate and the second substrate are packaged separately, and the second substrate is stacked on the top side of the first substrate instead of being in juxtaposition. Since the photo diode and the pixel transistors other than the transfer gate transistor of the pixel cell are located on two separate substrates respectively, the area of a photo diode region may be increased significantly, thereby greatly increasing full well capacitance of the image sensor and increasing a dynamic range, and reduce a dark current and image noise significantly, thereby improving the dark line noise and full well capacitance simultaneously.

  • Patent number: 11181442
    Abstract: A six-DOF motion testing and motion parameter decoupling method for rotors based on shaft-disk is proposed, which includes a displacement sensor tooling and a precision shaft-disk fixed on the rotor where three measuring points are arranged on the surface of disk to measure the axial motion of the rotor, two measuring points on the shaft to measure the radial motion, and the angle encoder at the shaft shoulder to measure the rotation motion. The tooling guarantees the accuracy of displacement sensors. The fixed coordinate system and the shaft-disk moving coordinate system are set, and the measured values of the displacement sensors and the encoder are represented by vectors to establish the relationship between the six-DOF motion of the shaft-disk axis and the measured values of sensors. Thus, the six-DOF motion of the rotor/shaft-disk can be determined by the measured data.

  • Publication number: 20210200573
    Abstract: Example virtual machine live migration methods and apparatus are described. In one example method, a first virtual machine which runs on a source server is migrated to a destination server. The source server includes a single-root input/output virtualization (SR-IOV) network adapter. The virtual machine manager delivers a live migration command to the live migration module. The live migration module obtains, according to the live migration command, information that needs to be migrated and that is about the first virtual machine, and reports the information to the virtual machine manager, where the information includes state information of the first virtual network adapter and memory data of the first virtual machine. The virtual machine manager sends the state information and the memory data of the first virtual machine to the destination server.
