The first Deep Trench Super-Junction MOSFET from Toshiba manufactured with a deep trench filling process 30% more efficient that the previous generation

The new generation Superjunction MOSFET from Toshiba has several new features.

First, the superjunction is not manufactured with a standard multi-epitaxy process but using a new deep trench filling process. This technique allows to narrow the pitch and results in a Rds(on) 30% lower. Moreover, the process simplification reduces the manufacturing cost by more than 20%.

Second, a trench gate replaces the traditional gate. The trench gate allows a greater reduction in the pitch and the Rds(on).

The DTMOS-4 MOSFET are targeted for power switching applications and offer a better power efficiency.
