1. Mechanism of oxidation process In an oxidation process of silicon that usually takes place at very high temperature (thermal oxidation)‚ silicon (Si) reacts with either water vapor (H20) or oxygen (O2) to form silicon dioxide‚SiO2 on the silicon surface. The reaction is represented by following equations: Dry oxidation: Si + O2 → SiO2 Wet oxidation: Si + 2H2O → SiO2 + 2H2 The oxidation process can be implemented through diffusion

potassium permanganate solution was titrated thrice to give clear Mn2+ with an analyte of acidified FeSO4 until all the Fe2+ in the solution was oxidized to Fe3+. The color of the MnO4-/Mn2+ was used as the indicator for the titration. A balanced oxidation-reduction‚ the molarity/normality of the standards potassium permanganate‚ and the volume of potassium permanganate used allowed the determination of the concentration of the FeSO4. Equipment and Chemicals: Chemicals: * Iron (II) ammonium sulfate
