  1. 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

  4. Based on the hydrodynamics energy transport model, the degradation induced by donor interface state is analyzed for deep - sub - micron grooved - gate and conventional planar pmosfet with different channel doping density. the simulation results indicate that the degradation induced by the same interface state density in grooved - gate pmosfet is larger than that in planar pmosfet, and for both devices of different structure, the impact of n type accepted interface state on device performance is far larger than that of p type. it also manifests that the degradation is different for the device with different channel doping density. the shift of drain current induced by same interface states density increases with the increase of channel do - ping density

    基於流體動力學能量輸運模型,對溝道雜質濃度不同的深亞微米槽柵和平面pmosfet中施主型界面態引起的器件特性的退化進行了研究.研究結果表明同樣濃度的界面態密度在槽柵器件中引起的器件特性的漂移遠大於平面器件,且電子施主界面態密度對器件特性的影響遠大於空穴界面態.特別是溝道雜質濃度不同,界面態引起的器件特性的退化不同.溝道摻雜濃度提高,同樣的界面態密度造成的漏極特性漂移增大
