Abstract :
A split-gate structure of power VDMOS is proposed in this paper. The p-base of the split-gate VDMOS is formed by self-aligned ion implanted. Only five masks is used to fabrication while the performance of the split-gate VDMOS is better than the conventional VDMOS. Compared to present structure, the split-gate structure can effectively reduce the device parasitic capacitances and the reliability is guaranteed. With the change of the distance between gates of the split-gate VDMOS, impact of the parasitic capacitances is analyzed.
