Wet Etching - University of Washington
labs.ece.uw.edu– Acetic acid has a lower dielectric constant than water • 6.15 for CH 3 COOH versus 81 for H 2 O • This produces less dissociation of the HNO 3 and yields a higher oxidation power for the etch. – Acetic acid is less polar than water and can help in achieving proper wetting of slightly hydrophobic Si wafers.
