Patent ID: 8207037

Claim:
A method for manufacturing a semiconductor component, comprising: providing a first semiconductor material having first and second opposing surfaces; forming at least one trench in the first semiconductor material, the at least one trench having at least one sidewall and first and second trench regions, the second trench region between the first surface and the first trench region; forming a dielectric material in the at least one trench, the dielectric material extending from the second trench region to the first trench region; forming a second semiconductor material in the first trench region of the at least one trench, the dielectric material between the second semiconductor material and the at least one sidewall of the at least one trench, the second semiconductor material serving as a first portion of a field plate; removing a portion of the dielectric material from the second trench region of the at least one trench to expose a portion of the at least one sidewall; forming a gate structure within the second trench region of the at least one trench and adjacent to the exposed portion of the at least one sidewall; and forming a third semiconductor material within the second trench region of the at least one trench, the third semiconductor material electrically separated from the gate structure and electrically coupled to the second semiconductor material, the third semiconductor material serving as a second portion of the field plate.
