Abstract

A combination of MOSFET gate-controlled diode measurements and a very sensitive electron spin resonance technique called spin-dependent recombination was utilized to observe and identify defect centers generated by a negative bias temperature stress in fully processed SiO 2-based pMOSFETs. In SiO 2 devices, the defects include two Si/SiO 2 interface silicon dangling bond centers (P b0 and P b1) and may also include an oxide silicon dangling bond center (E′). The observations indicate that both P b0 and P b1 defects play major roles in these SiO 2-based devices and suggest that E′ centers could play an important role.
