← ScienceWhich phenomenon limits photolithography resolution in microchip fabrication?
A)Diffraction limits pattern transfer fidelity✓
B)Refraction misaligns projection lens alignment
C)Polarization decreases photoresist exposure uniformity
D)Coherence enhances speckle in imaging system
💡 Explanation
Diffraction, resulting from the wave nature of light passing through small apertures causes blurring; this interference limits the minimum feature size because shorter wavelengths are needed for finer resolution. Therefore, spatial resolution degrades due to diffraction, rather than polarization, refraction, or coherence alone.
