Which outcome occurs when a pulsed laser etches silicon?

💡 Explanation

Material removal occurs because the pulsed laser focused onto silicon causes rapid heating and instantaneous vaporization, known as material ablation. Therefore, a precise amount of material is removed, rather than uncontrolled melting; direct electron excitation alone isn't sufficient.
