  • Patent number: 11640993
    Abstract: A shielded gate trench MOSFET device structure is provided. The device structure includes MOS gate trenches and p body contact trenches formed in an n type epitaxial silicon layer overlying an n+ silicon substrate. Each MOS gate trench includes a gate trench stack having a lower n+ shield poly silicon layer separated from an upper n+ gate poly silicon layer by an inter poly dielectric layer. The upper and lower poly silicon layers are also laterally isolated at the areas where the lower poly silicon layer extends to silicon surface by selectively removing portion of the upper poly silicon and filling the gap with a dielectric material. The method is used to form both MOS gate trenches and p body contact trenches in self-aligned or non self-aligned shielded gate trench MOSFET device manufacturing.

  • Patent number: 11601732
    Abstract: The present disclosure relates to a display system including a capsule image view, a 3D mini-map, and a 3D panoramic view, and a method of generating a 3D panoramic view. Specifically, according to the present disclosure, it is possible to infer the shape of an organ using a 3D mini-map and to simultaneously identify whether or not the capsule endoscope captures the images, and information on the position and posture of the capsule endoscope at primary captured points by visualizing the actual movement path of the capsule endoscope, thereby improving the accuracy of examination, and since multiple 2D images captured by a single capsule endoscope are able to be viewed as a single 3D panoramic image without changing the structure of the capsule endoscope, it is economical and the viewing angle of the image is able to be increased, thereby reducing the examination time and fatigue of the examiner.
