Abstract
A semiconductor device includes first, second and third trenches formed in a semiconductor layer having a first conductivity type. Each trench includes a corresponding field plate and a corresponding gate over each field plate. A first body region having a second opposite conductivity type is between the first and second gates, and a second body region having the second conductivity type is located between the second and third gates. A first source region is located over the first body region and a second source region is located over the second body region, the first and second source regions having the first conductivity type. A first gate bus is conductively connected to the first gate and a second gate bus is conductively connected to the second gate, the first gate bus conductively isolated from the second gate bus.
