Based on the hydrodynamic energy transport model, the influence of variation of negative junction depth caused by concave depth on the characteristics of deep - sub - micron pmosfet has been studied. the results are explained by the interior physical mechanism and compared with that caused by the source / drain depth. research results indicate that with the increase of negative junction depth ( due to the increase of groove depth ), the threshold voltage increases, the sub - threshold characteristics and the drain current driving capability degrade, and the hot carrier immunity becomes better in deep - sub - micron pmosfet. the short - channel - effect suppression and hot - carrier - effect immunity are better, while the degradation of drain current driving ability is smaller than those with the increase of depth of negative junction caused by source / drain junction shallow. so the variation of concave depth is of great advantage to improve the characteristics of grooved - gate mosfet
