Wet and Dry Etching ECE UC Davis
A wet etching process involves multiple chemical reactions that consume the original reactants and produce new reactants. The wet etch process can be described by three basic steps. (1) Diffusion of the liquid etchant to the structure that is to be removed. (2) The reaction between the

Stoichiometry (video) | Khan Academy
观看视频· Stoichiometry expresses the quantitative relationship between reactants and products in a chemical equation. Stoichiometric coefficients in a balanced equation indicate molar ratios in that reaction. Stoichiometry allows us to predict certain values, such as the percent yield of a product or the molar mass of a gas.
