  4. 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

    基於能量輸運模型對由凹槽深度改變引起的負結深的變化對深亞微米槽柵pmosfet性能的影響進行了分析，對所得結果從器件內部物理機制上進行了討論，最後與由漏源結深變化導致的負結深的改變對器件特性的影響進行了對比.研究結果表明隨著負結深（凹槽深度）的增大，槽柵器件的閾值電壓升高，亞閾斜率退化，漏極驅動能力減弱，器件短溝道效應的抑制更為有效，抗熱載流子性能的提高較大，且器件的漏極驅動能力的退化要比改變結深小.因此，改變槽深加大負結深更有利於器件性能的提高
