    摘要: A semiconductor and method for manufacturing a semiconductor device. In one embodiment the method includes providing a semiconductor substrate with a first substrate surface and at least one trench having at least one trench surface. The trench extends from the first substrate surface into the semiconductor substrate. The trench has a first trench section and a second trench section. The trench surface is exposed in an upper portion of the first and second trench sections and covered with a first insulating layer in a lower portion. A second insulating layer is formed at least on the exposed trench surface in the upper portion. A conductive layer is formed on the second insulating layer at least in the upper portion, wherein the second insulating layer electrically insulates the conductive layer from the semiconductor substrate. The conductive layer is removed in the first trench section without removing the conductive layer in the second trench section.

    摘要: A method of producing a semiconductor device includes providing a semiconductor body having a first surface and a dielectric layer arranged on the first surface and forming at least one first trench in the dielectric layer. The at least one first trench extends to the semiconductor body and defines a dielectric mesa region in the dielectric layer. The method further includes forming a second trench in the dielectric mesa region distant to the at least one first trench, forming a semiconductor layer on uncovered regions of the semiconductor body in the at least one first trench and forming a field electrode in the second trench.
