With the integration of integrated circuits improving continuously,the cleaning after chemical planarization(CMP)is particularly important in semiconductor technology.This paper introduces a kind of novel FA/O alkaline cleaning solutions.Its main ingredients include FA/OII chelating agent and O-20 non-ionic surfactant.FA/OII chelating agent is a kind of organic amine alkali.It not only adjusts the p H value,but also reacts with the Cu O and Cu(OH)_x and generates stable complex compound.At the same time,the...
