发明名称 HALFGELEIDERINRICHTING VOORZIEN VAN EEN METALLISERING VIA EEN VEELHEID VAN LAAGDIKTEN, EN EEN WERKWIJZE TER VERVAARDIGING ERVAN.
摘要 Structure and method for metallization patterns of different thicknesses on a semiconductor device or integrated circuit. The improved structure and method utilizes three layers of metal in order to reduce the required number of processing steps. One preferred embodiment entails a single metal deposition sequence followed by two etch steps, while a second embodiment, suitable for thicker metallization, requires only two depositions and two etch steps.
