Abstract:
In one general aspect, a power device can include a first Field Stop (FS) layer of a first conductivity type formed from a first-conductive-type semiconductor substrate. The first FS layer can include a first region having a constant impurity density profile along a depth direction and a second region having an impurity density profile along the depth direction lower than the impurity density profile of the first region. The power device can include a second FS layer of the first conductivity type disposed on a first surface of the first FS layer. The second FS layer can include a first implanted FS layer having an impurity density higher than an impurity density of the first FS layer, and a second implanted FS layer having an impurity density lower than the first implanted FS layer. The second implanted FS layer can be disposed between the first FS layer and the first implanted FS layer. The power device can include a transistor device having components disposed on the second FS layer.

Claim (Index 17):
The power device of  claim 16 , wherein a first sidewall of the trench is adjacent to a first side of the emitter region and the base region.
