Claim:
1. An electronic device comprising a transistor structure, comprising: a patterned semiconductor layer overlying a substrate and having a primary surface, wherein the patterned semiconductor layer defines a first trench and a second trench that extend from the primary surface towards the substrate, and wherein the first and second trenches are disposed in an active area of the electronic device; first conductive structures within each of the first and second trenches; a gate electrode within the first trench and electrically insulated from the first conductive structure; a first insulating member disposed between the gate electrode and the first conductive structure within the first trench; a second conductive structure within the second trench, wherein the second conductive structure is electrically connected to the first conductive structures and is electrically insulated from the gate electrode; a second insulating member disposed between the second conductive structure and the first conductive structure within the second trench, other first trenches substantially identical to the first trench; other gate electrodes within the other first trenches; other second trenches having different widths as compared to each other; and other second conductive structures within the other second trenches, wherein a ratio of a first number of gate electrodes to a second number of second conductive structures is in a range of approximately 0.75:1 to approximately 1.5:1.
