Abstract:
A lateral high-voltage transistor fabricated on a substrate comprising:an insulating layer that covers a top surface of the substrate; a drain region of a first conductivity type disposed above the insulating layer; a body region of a second conductivity type opposite to the first conductivity type disposed above the insulating layer; a plurality of parallel-arranged drift regions of the first conductivity type disposed above the insulating layer, each of the drift regions extending in a first direction from the drain region to the body region, adjacent ones of the drift regions being separated in a second direction orthogonal to the first direction by a dielectric layer; a field plate member disposed within each dielectric layer, the field plate member being fully insulated from the drift regions; a source region of the first conductivity type that adjoins the body region and is spaced-apart from the drift regions; and an insulated gate member disposed adjacent to the body region, with a channel region being defined in the body region adjacent the insulated gate member between the source region and at least one of the drift regions.
