Abstract:
1. A method for manufacturing a semiconductor component, comprising: providing a semiconductor material having first and second major surfaces; forming a plurality of trenches in the semiconductor material; forming a first layer of dielectric material over the plurality of trenches; forming a first electrode in a first portion of a first trench of the plurality of trenches, the first electrode having opposing sides and the first trench having at least one sidewall; thinning the first layer of dielectric material; recessing the first electrode in the first portion of the first trench of the plurality of trenches after thinning the first layer of dielectric material; further thinning the first layer of dielectric material to expose portions of the opposing sides of the first electrode after recessing the first electrode; forming a second layer of dielectric material over at least the first trench of the plurality of trenches; and forming a second electrode in a second portion of the first trench.
