PMOS transistors are less vulnerable to substrate noise since they’re placed in separate wells; designers implement guard rings to attenuate the substrate noise propagation. However, substrate noise ...

For years—decades, in fact—the NMOS transistor world has been on cruise control. NMOS is naturally faster and its performance has scaled better than PMOS. PMOS has had a cost advantage. But lately, it ...

Taking the final step in the quest for dual metal gates, SEMATECH engineers have demonstrated high-k/metal gate stacks that were used to build high-performance nMOS and pMOS transistors in a CMOS ...

As you probably know, processors – and most other digital technology – are made up of transistors. The simplest way to think of a transistor is as a controllable switch with three pins. When the gate ...
