← TechnologyWhich outcome results when high drain voltage causes short-channel MOSFET electrons to gain excessive kinetic energy?
A)Channel length modulation worsens sharply✓
B)Subthreshold leakage current decreases
C)Effective gate insulator thickness increases
D)Gate capacitance becomes more linear
💡 Explanation
Hot carrier injection into the gate oxide significantly worsens channel length modulation because the high-energy electrons can overcome the silicon-silicon dioxide barrier, becoming trapped in the gate oxide; therefore modulation worsens, rather than improved gate linearity or modified leakage.
