Abstract
An interconnect level includes upper and lower partial levels having respective conductive lines offset heightwise from each other. The interconnect level further includes respective dielectric portions separating adjacent conductive lines and extends above and below the conductive lines. At least one descending via connects a conductive line of the upper partial level with a lower element located below the dielectric portions of the interconnect level. The at least one descending via extends through the dielectric portions separating adjacent conductive lines of the lower partial level. At least one ascending via connects a conductive line of the lower partial level with an upper element located above the dielectric portions of the interconnect level. At least one ascending via extends through the dielectric portions separating adjacent conductive lines of the upper partial level.
