Method for passivating aluminum-based metallizations
摘要:
Aluminium-based alloy films and metallization layers that are patterned by reactive ion etching (RIE) are passivated by etching surface portions of the films or layers with a phosphoric-chromic mixture to remove contaminants and then oxidizing the exposed surface portions in an oxygen atmosphere.
