Plasma Damage of Gate Oxide through the Interlayer Dielectric

Shuji Hirao; Tatsuo Sugiyama; Takehito Yoshida; Kousaku Yano; Noboru Nomura

The degradation of thin gate oxides connected with the interconnect under the interlayer dielectric(IlD) by Ar plasma inadiation was observed. The electric field of gate oxide breakdown and the total charge to breakdovn(QBD were dependent on the material of the ILD. The current density through the ILD, calculated from QBD, was nearly equal to the measured value. Plasma damage through the ILD is caused mainly by the leakage current of the ILD. A-3-3
