  • Patent number: 12068313
    Abstract: A semiconductor arrangement and method of forming the same are described. A semiconductor arrangement includes a first gate structure on a first side of an active area and a second gate structure on a second side of the active area, where the first gate structure and the second gate structure share the active area. A method of forming the semiconductor arrangement includes forming a deep implant of the active area before forming the first gate structure, and then forming a shallow implant of the active area. Forming the deep implant prior to forming the first gate structure alleviates the need for an etching process that degrades the first gate structure. The first gate structure thus has a desired configuration and is able to be formed closer to other gate structures to enhance device density.

  • Patent number: 12056944
    Abstract: An efficient and robust high-speed neural networks for cell image classification is described herein. The neural networks for cell image classification utilize a difference between soft-max scores to determine if a cell is ambiguous or not. If the cell is ambiguous, then the class is classified in a pseudo class, and if the cell is not ambiguous, the cell is classified in the class corresponding to the highest class score. The neural networks for cell image classification enable a high speed, high accuracy and high recall implementation.
