Which outcome results when quantum tunneling exceeds implant threshold?

A)Logic gate threshold voltage drop
B)Decreased channel carrier mobility
C)Increased transistor dynamic power
D)Increased subthreshold leakage current

💡 Explanation

Increased subthreshold leakage current results with quantum tunneling occurring in MOSFET transistors within integrated circuits, because electrons tunnel through the gate oxide layer, increasing off-state current. Therefore leakage escalates, rather than a threshold drop occurring.
