Abstract
A method includes forming separate conductive trench structures in a trench and then removing an upper portion of one of the conductive structures where the remaining portion serves as field gate for a transistor. Removing the upper portion includes forming a second trench. The second trench is filled with a gate material that is used as a gate for the transistor. The transistor includes a source region for the transistor on the side of the trench and a drain region for the transistors on the other side of the trench, wherein the drain region includes a portion located at an upper portion of a semiconductor material. The transistor includes a channel region having a portion located along a sidewall of a trench.
