← ScienceWhich outcome occurs due to electron scarcity in deep submicron transistors?
A)Increased gate oxide leakage✓
B)Suppressed drain-induced barrier lowering
C)Decreased transistor threshold voltage
D)Enhanced channel hot carrier injection
💡 Explanation
Increased gate oxide leakage occurs because decreased channel length accentuates **quantum tunneling** through the thin gate oxide. Thus electrons tunnel through the gate oxide barrier rather than following lower resistance paths, therefore creating leakage, not reduced barrier lowering.
