Abstract
The roughness of "bird\´s-beak" frontline prior to gate oxidation has been revealed for the first time to degrade gate oxide reliability in TDDB. This new mechanism identifies the "extrinsic" Qbd responses to electrical fields. The restorations of intrinsic Qbd have been realized by post-fabrication anneals or process improvement.
