Abstract :
P+ walls through wafer can be considered as a region key in the 3D architecture of new bi-directional current and voltage power integrated devices. In this paper, we demonstrate the possibility of fabricating these P+ walls combining the deep RIE of silicon and deposit of boron doped polysilicon.
