  • Patent number: 5902122
    Abstract: A method of manufacturing a semiconductor device is provided. A first interlayer insulating layer is formed on a silicon substrate, and a lower metal layer is formed on the first interlayer insulating layer. A first insulating layer is formed on the first interlayer insulating layer including the lower metal layer, moisture contained in the first insulating layer is removed by N.sub.2 or N.sub.2 O plasma. Thereafter, a SOG layer and a second insulating layer are sequentially formed on the first insulating layer.
