Abstract
Consistent with an example embodiment, a trench FET has source regions arranged above insulated gates in trenches. A body region of opposite conductivity type is arranged between the trenches and a body region is arranged above the body region. Source contact metallisation contacts the source and body contact region. In this way a small cell pitch can be achieved.
