Corrosion during cmp
WebCorrosion experiments were performed on X65 carbon steel in autoclaves containing supercritical CO2 at 80 bar and 35 degrees C in the presence of 0, 50, and 100 ppm (mole) SO2. General and localized corrosion rates were determined over a period of 48 h through the implementation of gravimetric analysis and surface profilometry, respectively. http://cden.ucsd.edu/internal/Publications/workshop_archive/2005_Sep/posters/CMP_Wang_Doyle.pdf

WebOct 1, 2024 · There are four types of corrosion that are known to occur during W CMP: 1. chemical corrosion due to the photo-induced chemical reaction of W with chemicals in the slurry [4]; 2. galvanic corrosion resulting from two dissimilar metals that are electrically connected and exposed to the same electrolyte [5]; 3. seam voids which are generated … WebMar 23, 2024 · The CMP mechanism used in citric-acid-based slurry and the H 2 O 2 as oxidizer were presented in ref. [ 9 ]. Their results show that the copper anodic reaction is provoked by the increase in corrosion potential and, hence, the passivation layer of copper oxide is increased and the copper dissolution is reduced.
