Which outcome occurs when photoresist is overexposed during lithography?

A)Decreased feature resolution occurs
B)Increased pattern edge sharpness
C)Improved etch resistance results
D)Enhanced adhesion to substrate arises

💡 Explanation

Overexposure causes increased crosslinking via **photopolymerization**, broadening the developed features; therefore resolution decreases, because features are larger than intended, rather than sharper, especially since development kinetics now involve more photoresist.
