    摘要: A method of etching a low dielectric constant material with an aqueous solution of hydrofluoric acid and hydrochloric acid. The etching solution is particularly useful on low dielectric constant materials that are water repulsive or hydrophobic. The weight ratio of hydrofluoric acid to hydrochloric acid in the aqueous solution ranges from 1:3 to 4:1.
