  • Publication number: 20210074820
    Abstract: Various embodiments of the present disclosure are directed towards a method for forming an integrated chip. The method includes forming a source region and a drain region within a substrate. A drift region is formed within the substrate such that the drift region is disposed laterally between the source region and the drain region. A first gate structure is formed over the drift region. An inter-level dielectric (ILD) layer is formed over the first gate structure. The ILD layers is patterned to define a field plate opening. A first field plate layer, a second field plate layer, and a third field plate layer are formed within the field plate opening.

  • Patent number: 10861946
    Abstract: Various embodiments of the present disclosure are directed towards an integrated chip including a field plate disposed over a drift region. A first gate electrode overlies a substrate between a source region and a drain region. An etch stop layer laterally extends from an outer sidewall of the first gate electrode to the drain region. The etch stop layer overlies the drift region disposed between the source region and the drain region. A field plate is disposed within a first inter-level dielectric (ILD) layer overlying the substrate. The field plate overlies the drift region. A top surface of the field plate is aligned with a top surface of the first gate electrode and a bottom surface of the field plate is vertically above a bottom surface of the first gate electrode. The field plate and first gate electrode respectively include metal materials.

  • Patent number: 10141401
    Abstract: A method for forming a semiconductor device structure is provided. The method includes performing a first plasma etching process on a substrate to form a first trench in the substrate. The method includes removing a second portion of the substrate under the bottom surface to form a second trench under and connected to the first trench. The second trench surrounds a third portion of the substrate under the first portion. The third portion has a first sidewall. The first sidewall is inclined relative to the top surface at a second angle, and the first angle is greater than the second angle. The method includes forming an isolation structure in the first trench and the second trench. The method includes forming a gate insulating layer over the top surface and the first inclined surface. The method includes forming a gate over the gate insulating layer and the isolation structure.
