  • Patent number: 11908916
    Abstract: A high voltage semiconductor device includes a semiconductor region of a first conductivity type having a first region and a second region, a first insulation pattern disposed over the first region of the semiconductor region to have a first thickness, a second insulation pattern disposed over the second region of the semiconductor region to have a second thickness greater than the first thickness, and a gate electrode disposed over the first and second insulation patterns to have a step structure over a boundary region between the first and second regions. The gate electrode has a doping profile that a position of a maximum projection range of impurity ions distributed in the gate electrode over the first region is located at substantially the same level as a position of a maximum projection range of impurity ions distributed in the gate electrode over the second region.

  • Patent number: 10978587
    Abstract: The present examples relate to a semiconductor device used in an electric device or high voltage device. The present examples improve Rsp by minimizing drift region resistance by satisfying breakdown voltage by improving the structure of a drift region through which current flows in a semiconductor device to provide optimal results. Moreover, a high frequency application achieves useful results by reducing a gate charge Qg for an identical device pitch to that of an alternative technology.

  • Patent number: 10586863
    Abstract: Provided are a low-cost semiconductor device manufacturing method and a semiconductor device made using the method. The method includes forming multiple body regions in a semiconductor substrate, forming multiple gate insulating layers and multiple gate electrodes in the body region; implementing a blanket ion implantation in an entire surface of the substrate to form a low concentration doping region (LDD region) in the body region without a mask, forming a spacer at a side wall of the gate electrode, and implementing a high concentration ion implantation to form a high concentration source region and a high concentration drain region around the LDD region. According to the examples, devices have favorable electrical characteristics and at the same time, manufacturing costs are reduced. Since, when forming high concentration source region and drain regions, tilt and rotation co-implants are applied, an LDD masking step is potentially omitted.
