Abstract
A transistor device includes a substrate, a first current-carrying region having a first lateral width, and a second current-carrying region. A first trench is formed between the first current-carrying region and the second current-carrying region. The first trench includes a first vertical component sidewall coupled to the first current-carrying region and a second vertical component sidewall coupled to the second current-carrying region. A first termination region includes a first termination portion coupled to the first current-carrying region, a second termination portion coupled to the second current-carrying region, and a first trench termination portion coupled to the first trench. The first trench and the first trench termination portion surround a portion of the first current-carrying region, and the second current-carrying region and the second termination portion surrounds a portion of the first trench and the first trench termination portion. A width of the first termination portion exceeds the first lateral width.
