WebDec 9, 2024 · Step 1 The reactant molecules, H 2 and Cl 2, break down into their atoms. H 2 (g) → 2 H (g) Cl 2 (g) → 2 Cl (g) Step 2 These atoms combine to form HCl molecules. 2 H (g) + 2 Cl (g) → 2 HCl (g) In the first step, the H-H and Cl-Cl bonds are broken. In both cases, one mole of bonds is broken. tim.pl nipWebAug 20, 2024 · Modeling of dry etching processes requires a detailed understanding of the relevant reaction mechanisms. This study aims to elucidate the gas-phase mechanism of reactions in the chemical dry etching process of SiO 2 layers which is initiated by mixing NF 3 gas with the discharged flow of an NH 3 /N 2 mixture in an etching chamber.
