← ScienceWhich outcome impairs microchip function when dopants diffuse unevenly?
A)Reduced depletion zone size
B)Channel length modulation changes✓
C)Shallow junction thermionic conductivity
D)Schottky barrier lowering increases
💡 Explanation
Increased dopant concentration causes transistor drain current leakage, therefore channel length modulation increases and device switching fails, because the drain encroaches further into the channel rather than other effects being primary.
