Abstract:
A vertical high-voltage transistor comprising:a drain region of a first conductivity type; a plurality of body regions of a second conductivity type opposite to the first conductivity type; a plurality of drift regions of the first conductivity type, each of the drift regions extending in a first direction from the drain region to one or more of the body regions; field plate members that extend in the first direction, each of the field plate members being spaced-apart in a second direction and insulated from the drift regions by a dielectric layer; a plurality of source regions of the first conductivity type, each of the source regions adjoining one of the body regions; at least one insulated gate member disposed above each body region, thereby defining a channel region that extends in the second direction from one of the source regions to one of the drift regions.
