RCA-1 Silicon Wafer Cleaning - INRF

oxidative desorption and complexing with H2O2-NH4OH-H2O (RCA1). A second RCA-2 clean (SC-2) is often used H2O2-HCI-H2O to further clean the surface. RCA-1 clean is used to remove organic residues from silicon wafers. In the process, it oxidizes the silicon and leaves a thin oxide on the surface of the wafer, which should be removed

Chemical Vapor Deposition (CVD) • Deposition can also take place due to a chemical reaction between some reactants on the substrate. • In this case reactant gases (precursors) are pumped in to a reaction chamber (reactor). • Under the right conditions (T, P), they undergo a reaction

Chemical Vapor Deposition (CVD)

Chemical vapour deposition may be defined as the deposition of a solid on a heated surface from a chemical reaction in the vapour phase. It belongs to the class of vapour-transfer processes which is atomistic in nature, that is the deposition species are atoms or molecules or a combination of these. Schematic of a simple thermal CVD reactor

Chemical Vapor Deposition

• Chemical vapor deposition (CVD) is the most important process in microfabrication. • It is used extensively for producing thin films by depositing many different kind of foreign materials over the surface of silicon substrates, or over other thin films that have already been deposited to the silicon substrate.
