  • Publication number: 20240096989
    Abstract: The present application discloses an MV device, wherein a first gate structure of the MV device is formed by stacking a first gate dielectric layer and a first gate conductive material layer. The first gate dielectric layer is divided into a body gate dielectric layer and an edge gate dielectric layer. The body gate dielectric layer is located in a middle region, and the edge gate dielectric layer surrounds the periphery of the body gate dielectric layer. A channel region is located in a surface of the semiconductor substrate between the lightly doped drain regions on the two sides of the first gate structure. In a channel length direction, the top of the channel region is covered by the body gate dielectric layer. The present application also discloses a method for manufacturing the MV device.

  • Patent number: 11422280
    Abstract: A method for determining properties of a laminated formation traversed by a well or wellbore employs measured sonic data, resistivity data, and density data for an interval-of-interest within the well or wellbore. A formation model that describe properties of the laminated formation at the interval-of-interest is derived from the measured sonic data, resistivity data, and density data for the interval-of-interest. The formation model represents the laminated formation at the interval-of-interest as first and second zones of different first and second rock types. The formation model is used to derive simulated sonic data, resistivity data, and density data for the interval-of-interest. The measured sonic data, resistivity data, and density data for the interval-of-interest and the simulated sonic data, resistivity data, and density data for the interval-of-interest are used to refine the formation model and determine properties of the formation at the interval-of-interest.
