电子辐照消除CMOS电路自锁效应的探讨
Studies on the Possibility of Eliminating the CMOS Latch-up by Electron Irradiation
【摘要】 <正> CMOS电路中存在着pnpn寄生可控硅结构,见图1(a),它比实际可控硅的结构多两个分流电阻Rn和Rp,见图1(b)、(c).若寄生npn和pnp晶体管的电流增益分别为βnpn和βpnp,这时导通条件便由理想可控硅的βnpn·βpnp=1变为βnpn·βpnp=
【Abstract】 The possibility of eliminating the CMOS latch-up by means of electron irradiationhas been investigated.It appears that the electron irradiation together with a properannealing can significantly reduce the current gain of parasitic npn and pnp transis-tors without any degradation of CMOS papamecers.The characteristics of the devicesafter treatment are rather stable.Therefore electron irradiation might be a plausiblemethod for eliminating CMOS latch-up.
