| 摘要 |
A field-effect transistor includes a semiconductor substrate, a source region formed in the semiconductor substrate, a drain region formed in the semiconductor substrate, a channel region formed in the semiconductor substrate, wherein the source region is connected to a source terminal electrode and the drain region is connected to a drain terminal electrode, wherein the channel region comprises a first narrow width channel region and a second narrow width channel region connected in parallel regarding the source terminal electrode and the drain terminal electrode, and wherein the first narrow width channel region and/or the second narrow width channel region comprise lateral edges narrowing the width of the narrow width channel region is such a way that a channel formation in the narrow width channel region is influenced by a mutually influencing effect of the lateral edges, and a gate electrode arranged above the first and second narrow width channel regions.
