Patents by Inventor Soon-Byung Park

Soon-Byung Park has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 12108587
    Abstract: The present invention relates to the field of semiconductor manufacturing technologies, in particular to a semiconductor device and a method of forming the same. The method of forming the semiconductor device includes the following steps: forming a substrate with a trench, a gate dielectric layer covering an inner wall of the trench, a barrier layer covering a portion of a surface of the gate dielectric layer, and a first gate layer filled on an surface of the barrier layer being disposed in the trench; removing a portion of the barrier layer to form an groove located between the first gate layer and the gate dielectric layer; forming a channel dielectric layer at least covering an inner wall of the groove and a top surface of the first gate layer; and forming a second gate layer at least partially filling an interior of the groove.

  • Patent number: 7041594
    Abstract: A first conduction type well is formed in a substrate, and a second conduction type impurity region is formed in the well. A lower interlayer dielectric is formed on the substrate, including the well and the impurity region. A contact plug, connected to the impurity region through the lower interlayer dielectric, is formed with a void inside it. An upper interlayer dielectric is formed on the lower interlayer dielectric and the contact plug. The upper interlayer dielectric is selectively etched, forming an interconnection groove exposing the contact plug. The contact plug and the exposed void are overetched, extending the void into the first conduction type well. The interconnection groove is filled with a conductive layer, forming an interconnection. A seam extending to the well is formed in the void, connecting the contact plug to the well. Due to the seam, a well bias may be applied to the well.
