← ScienceLaser interference lithography creates nanoscale patterns; which consequence results when vibrations are present during the exposure?
A)Reduced pattern resolution and blurring✓
B)Enhanced etching depth and uniformity
C)Increased process throughput drastically
D)Improved resist adhesion substantially
💡 Explanation
Vibrations introduce stage displacement and affect constructive interference. The optical path fluctuation causes *destructive interference*, therefore blurring edges and reducing resolution, rather than sharper features, because sharp features rely on stationary interference to properly expose the resist.
