Abstract:
A semiconductor substrate having at least one high electrical conductivity interconnect, wherein said substrate comprising at least one p/n junction in electrical contact with a metallic via-plug, at least one first insulator layer over said semiconductor substrate and surrounding said first metallic via-plug, at least a portion of at least one first level of high electrical conductivity interconnection line in contact with said first metallic via-plug, wherein a second and a third insulator layers are over said first insulator layer and surrounds said first level electrical interconnection line, at least a portion of at least one second level electrical interconnection line in contact with said first level electrical interconnection line through at least one high electrical conductivity via-plug, wherein at least a fourth and a fifth insulator layers are over said third insulator layer and surrounds said second level electrical interconnection line, and wherein each adjoining insulator layer is of a different material, and thereby forming said semiconductor substrate having at least one high electrical conductivity interconnect.
