Assignee: PURDUE RESEARCH FOUNDATION
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device, comprising:
at least a first lateral MOSFET formed on a semiconductor substrate, the first lateral MOSFET having an interface defined by a plurality of trenches along which the current flow can be modulated by a perpendicular electric field, wherein at least a portion of the interface lies on a plane substantially perpendicular to the plane of the substrate, the interface configured such that at least a portion of the current flow along the portion of the interface that lies on a plane substantially perpendicular to the plane of the substrate is in a direction substantially parallel to the plane of the substrate; and
wherein a base region of the first lateral MOSFET is disposed below the plurality of trenches and has a substantially flat and coplanar upper surface portions disposed under drain and source regions of the first lateral MOSFET.
