  • Composite insulator structure
    Patent number: 4601939
    Abstract: A composite insulator structure separating adjacent layers of patterned metal on an LSI chip is disclosed. The bottom layer of sputtered oxide is thicker than the top layer and is preferably planarized. The top layer is conformal plasma nitride so as to uncover unwanted projections on the underlying metal and prevent interlevel shorting between the patterned layers.
