← ScienceWhich risk increases when a high-powered laser etches silicon?
A)Plasma formation above the surface✓
B)Increased material tensile strength values
C)Decrease of the ambient gas pressure
D)Reduced etching process material ablation
💡 Explanation
Laser etching involves rapid heating; ablation may create plasma above the silicon due to localized, high energy density from the photons through inverse bremstrahlung. Therefore, plasma ignition is a risk, rather than induced tensile strength because the process is material ablation.
