	2	Mechanism of oxide thickness and temperature dependent current conduction in n^+-polySi/SiO_2/p-Si structures—a new analysis显示文摘The conduction mechanism of gate leakage current through thermally grown silicon dioxide(Si02)films on(100) p-type silicon has been investigated in detail under negative bias on the degenerately doped n-type polysilicon(n+-polySi) gate.The analysis utilizes the measured gate current density J_G at high oxide fields E_(ox) in5.4 to 12 nm thick Si02 films between 25 and 300 ℃.The leakage current measured up to 300 ℃ was due to Fowler-Nordheim(FN) tunneling of electrons from the accumulated n+-polySi gate in conjunction with Poole Frenkel(PF) emission of trapped-electrons from the electron traps located at energy levels ranging from 0.6 to 1.12 eV(depending on the oxide thickness) below the Si02 conduction band(CB).It was observed that PF emission current I_(PF) dominates FN electron tunneling current I_(FN) at oxide electric fields E_(OX) between 6 and 10 MV/cm and throughout the temperature range studied here.Understanding of the mechanism of leakage current conduction through Si02 films plays a crucial role in simulation of time-dependent dielectric breakdown(TDDB) of metaloxide-semiconductor(MOS) devices and to precisely predict the normal operating field or applied gate voltage for lifetime projection of the MOS integrated circuits.
