SiGe quantum-well pMOSFETs have recently been introduced for enhanced performance of transistors. Quite surprisingly, a significant reduction in negative bias temperature instability (NBTI) was also found in these devices. Furthermore, a stronger oxide field acceleration of the degradation in SiGe devices compared with Si devices was reported. These… CONTINUE READING
