← ScienceWhich consequence results when a plasma etcher's chamber walls catalyse radical recombination?
A)Increased substrate etch isotropy
B)Reduced effective etch rate✓
C)Enhanced micro-loading effect
D)Improved feature profile uniformity
💡 Explanation
Reduced effective etch rate happens because surface recombination depletes etchant radicals; this decreases the radical concentration at the substrate surface, therefore the etch rate diminishes, rather than causing profile changes.
