  • Patent number: 9455329
    Abstract: A junctionless semiconductor device having a buried gate, a module and system each having the same, and a method for forming the semiconductor device are disclosed. A source, a drain, and a body of a semiconductor device having a buried gate are doped with the same type of impurities, so that the junctionless semiconductor device does not include a PN junction between the source and the body or between the body and the drain. As a result, a leakage current caused by GIDL is reduced so that operation characteristics of the semiconductor device are improved and the size of a current-flowing region is increased, resulting in an increased operation current.

  • Patent number: 8194171
    Abstract: An image sensing apparatus, particularly, an apparatus for optically combining visible images with far-infrared images is provided in which performing a separate signal processing may not be needed. The image combining apparatus emits light that is sensed by an image sensor, and reflects the light toward the image sensor in response to far-infrared rays being sensed from an object, thereby converting far-infrared information into information that can be sensed by the image sensor.
