Abstract(in English) | We studied for the degradation of p^+ polysilicon gated pMOSFETs under positive bias temperature (+BT) stress and the recovery by the baking. The following facts were found. 1.Under+BT stress, the p^+ polysilicon gated pMOSFETs was degraded by the interface trap generation. This phenomenon does not occur in the n^+ polysilicon gated pMOSFETs. The silicon-hydrogen bonds at the Si/SiO_2 become the interface traps by the influence of the hydrogen. 2.The interface traps which generated under +BT stress recover easily by the baking. We consider that this recovery is the influence of the hydrogen, too. 3.The activation energy of the +BT instability and the recovery were 1.2eV and 1.0eV, respectively. This difference 0.2eV is the energy gap between the silicon-hydrogen bonds and the interface state. |
