← ScienceWhich consequence results when a metal-oxide-semiconductor capacitor's gate dielectric degrades?
A)Increased gate leakage current✓
B)Reduced channel carrier mobility
C)Enhanced subthreshold swing slope
D)Lower breakdown supply voltage
💡 Explanation
Increased gate leakage occurs because the Tunneling mechanism allows current to flow through the damaged dielectric, therefore increasing leakage, rather than affecting carrier mobility, subthreshold swing, or breakdown voltage which are parametric shifts because design flaws cause failure.
