Brown oxide pretreatment composition for cleaning copper surface and improving adhesion of polyimide surface, and method for improving adhesion of polyimide surface by applying the same to brown oxide process |
摘要 |
Disclosed herein are a brown oxide pretreatment composition for cleaning a copper surface and improving adhesion of a polyimide surface, and a method for improving adhesion of a polyimide surface by applying the composition to a brown oxide process. The brown oxide pretreatment composition for cleaning a copper surface and improving adhesion of a polyimide surface comprises, 5~15 g/L of an amine; 190~210 g/L of a hydroxide compound; at least one additive selected from 3~6 g/L of a cleaner adjuvant, 0.1~5 g/L of a antifoaming agent and 1~10 g/L of a precipitation inhibitor; and the balance of water. When the brown oxide pretreatment composition for cleaning a copper surface and improving adhesion of a polyimide surface is applied to a pretreatment step of a brown oxide process, it can clean a copper surface and improve adhesion of a polyimide surface.
