  • Patent number: 9911688
    Abstract: A semiconductor device includes a semiconductor chip substrate with a chip region and a scribe lane region, center and boundary pads respectively provided on the chip and scribe lane regions, a lower insulating structure provided on the chip region and the scribe lane region, a first conductive pattern including a contact portion, a conductive line portion, and a bonding pad portion, and an upper insulating structure defining first and second openings formed on the bonding pad portion and the boundary pad. The lower insulating structure includes a plurality of lower insulating layers, which are sequentially stacked on the substrate, and each of which is a silicon-containing inorganic layer.
    Type: Grant
