  • 本文研究了90nm CMOS工艺下栅氧化层厚度为1.4 nm沟道长度为100 nm的轻掺杂漏(LDD)nMOSFET栅电压VG对栅致漏极泄漏 (GIDL)电流Id的影响,发现不同VG下ln (Id/(VDG-1.2))-1/(VDG-1.2)曲线相比大尺寸厚栅器件时发生了分裂现象. 通过比较VG变化下ln(Id/(VDG-1.2))的差值,得出VG与这种分裂现象之间的作用机理,分裂现象的产生归因于VG的改变影响了GIDL电流横向空穴隧穿部分所致. 随着|VG|的变小,ln(Id/(VDG-1.2))曲线的斜率的绝对值变小.进一步发现不同VG对应的ln (Id/(VDG-1.2))曲线的斜率c及截距d与VG呈线性关系,c,d曲线的斜率分别为3.09和-0.77. c与d定量的体现了超薄栅超短沟器件中VG对GIDL电流的影响,基于此,提出了一个引入VG 影响的新GIDL电流关系式.
    The influence of gate voltage VG on gate induced drain leakage (GIDL) current is studied in LDD nMOSFET with a gate oxide of 1.4nm and a channel length of 100nm. It is found that the split phenomena of ln(Id/(VDG-1.2))-1/(VDG-1.2) curves under different VG values occurs, which are different from the large MOSFET. Through comparing varieties of ln(Id/(VDG-1.2)) of different VG values, the mechanism of this split phenomenon is obtained. This is ascribed to the change of the hole-tunneling part of GIDL current under different VG values. The absolute value of ln(Id/(VDG-1.2)) curve slope decrease with |VG| value decreasing . It is further found that the values of slope c and intercept d of ln(Id/(VDG-1.2)) curves are linear with VG and the slopes of c and d are 3.09 and -0.77, respectively. The values of c and d quantificationally show the influence of VG on the GIDL current in an ultra-thin ultra-short MOSFET. On the basis of these results, a new GIDL current model including VG is proposed.
