Which limitation exists because of quantum tunneling in CMOS scaling?

💡 Explanation

Increased gate dielectric thinning causes a significant rise in undesirable gate leakage current, because electrons tunnel through potential energy barriers; therefore, leakage increases exponentially rather than decreasing with expected scaling, impacting performance.
